Which of the manufacturers of building levels to buy. How to choose a bubble building level

The building level is a tool that detects the slope of surfaces. Suitable for indoor and outdoor use.

How they work

The algorithm of operation of any of them is reduced to the choice of the installation point and the place for measuring the level. The remaining options depend on the particular type of tool and can be combined.

The building level helps:

1. Determine the verticality or horizontality of a given surface - in order to establish a further scope of work and its necessity.
2. To find out in which direction the tilt occurred, in some models its exact size is also available.
3. Set clear guidelines when marking surfaces - before installing frames or furniture.
4. Calculate the volume of materials - for this, the arithmetic mean of the levels of different points on the same surface is used.
5. Determine a single level in different rooms - often required when installing ceilings or windows.

In low-rise construction or apartment renovation, manual tool variations are more often used. These are devices without complex electronics that do not require special skills. Professionals use several types at the same time.

Types and functions of building levels

hydraulic levels

The functioning of this type of instrument is based on the law of physics about communicating vessels. Structurally, hydraulic levels are two flasks connected by a transparent tube.

Peculiarities:

• This is an accurate view of the levels, but it is important to keep the hose free of kinks and have good eyesight.
• Suitable for checking slopes simultaneously in different rooms.
• As a rule, they require pair work.

To bring the device into working condition, it is enough to fill it with water so that the upper meniscus of the liquid reaches the middle of both flasks, and no air bubbles remain in the tube.

Bubble building levels

Regardless of the size and design features, the principle of the device is the same. At least two flasks are built into the body of the level, where small air bubbles “float” in the liquid. Focusing on them, they check if there is a slope of the planes.

Peculiarities:

• The liquid in most cases will be industrial alcohol. Allows you to measure with an accuracy of 1 mm / m - this is the industry standard.
• "Air" bubbles of solid acrylic suggest greater precision. Accuracy 0.5 mm/m.

Some models of bubble levels are equipped with flasks on a rotating base. This allows you to work with inclined planes. Profile shapes are in the form of a box, a trapezoid and with one measuring plane cast Shark (shark). Part of the tool is equipped with end elements that prevent breakage during falls.

Laser building levels

The convenience of this equipment lies in the non-contact use and in a large area of ​​marking coverage.

Peculiarities:

• The pendulum of devices is leveled after unlocking. It is desirable to set the base plane horizontally.
• Manufacturers offer an additional mounting tripod, but its dimensions are not enough for marking at a height. In this case, a bar is used, which is fixed between the floor and another horizontal surface. The platform on which the tool is installed moves along it.
• In bright light, the laser beam is not visible to the naked eye. To resolve the issue, glasses with glasses in the red color range are used.

Part of the laser levels produces static vertical and horizontal lines in a limited sector. An alternative option using a dot running in a circle allows marking from all sides simultaneously.

Magnetic building levels

Magnetic levels are visually indistinguishable from bubble levels. The difference is noticeable only on the lower ends. This option is equipped with magnets for easy work with metal surfaces.

Peculiarities:

• Bar magnets are more commonly used in polymer levels, in combination with a V-groove for ease of use on pipelines.
• Ceramic magnets or ferrites have been the industry standard in levels up until recent years.
• Rare earth - most aluminum models now come with this type of magnet. They are up to 10 times stronger than ceramic.

This type of level is more often used for works related to the installation of frames for drywall, as it is conveniently attached to ceiling and rack profiles, leaving hands free.

Optical building levels

An optical level or level is used in industrial facilities or in the construction of houses. The kit includes a special tripod, without which the use of the instrument is unproductive. Installation comes down to mounting, focusing and centering.

Peculiarities:

• Centering is needed for point-to-point measurements. It is carried out using a construction plumb line attached to the bottom of the tripod.
• Focusing - the telescope is aimed at the rail, with the help of an adjusting screw, the clarity is adjusted. The eyepiece ring defines the reticle.

After adjustment, the height marks are taken. The collected data are summarized, their arithmetic mean is calculated. It will be the mark of the base from the horizon of the instrument.

Advantages

Each type has its own set of advantages:

• hydraulic levels . They support measurements in different rooms, when the initial level is hidden by partitions or heavy structures. This functionality is not available in other models.
• Bubble . Easy to install and use, light weight and dimensions. Possibility of use for measuring the level and at the same time checking the plane of the wall or floor.
• Magnetic . Do not require additional fixation when working with metal. They have a full set of advantages of bubble models.
• Laser . Supports simultaneous vertical and horizontal measurements. The coverage range is higher than any of the manual models. Automation of routine processes.
• Optical . Applicability in open spaces, in the construction of roads and large facilities. Functionality, saving time and labor costs. When measuring at a distance, the accuracy does not decrease.

Problems

Disadvantages and inconveniences also depend on the type of tool:

• Hydro. M obscure and difficult to use. The routine processes of filling, draining, unwinding and forcing out bubbles are time consuming. Not suitable for vertical planes.
• Bubble . Often goes astray, adjustment is often not available. Not suitable for work over long distances and areas. In adjacent rooms, the correct level cannot be determined.
• Magnetic . The same disadvantages as the bubble. Magnets often protrude from the plane of the rib - when measuring, fresh paint or putty can be damaged. Some models are less stable than bubble ones. Frequent failure of magnets is also a disadvantage.
• laser . Requires a flat surface. The pendulum during transportation often fails. With distance, the diameter of the beam increases, which affects the accuracy. Plane measurements can only be made using optional accessories.
• Optic . Adjustment is time consuming and requires skill. For domestic purposes, the functionality is redundant - neither the time costs nor the costs are justified.

How to choose a building level

For most types of levels, accuracy will be the defining indicator, so checking its correctness is important.

bubble and magnetic

The same design also implies uniform methods for assessing the correctness of indications.

To check a horizontal flask, you need:

1. Place the tool on a flat surface.
2. Make two marks: at the end of the level and along - near the horizontal ampoule.
3. Note the position of the air bubble.
4. Turn the spirit level 180° and set in the same place according to the previously made marks.
5. Check the position of the air bubble. Any difference in its position before and after the level flip indicates that the instrument is inaccurate.
6. Repeat the test even if the readings match.

To check a vertical flask, set the level on a door frame or a flat wall, further steps are similar to horizontal measurements.

Hydro

In this type of measuring instruments there are no structural details responsible for the accuracy of measurements, but there are nuances that should be considered when choosing:

• The length of the hose - you should not choose it in reserve, because the extrusion of air bubbles and the straightening of the tubes can turn this advantage into a problem.
• Pay attention to the tightness of the protective caps. Water should not pour out - this will interfere with work.
• It is worth checking the integrity of the tube and the connections with the flasks.

An additional parameter is the flexibility of the hose, but it is difficult to evaluate it without having experience with this type of level.

laser

The choice of a laser level involves reconciliation of a number of indicators:

• Measurement error - should not exceed 3 mm per 10 meters.
• Self-alignment - test multiple models. The preferred option is the pendulum of which levels out faster than in analogues.
• Range - marked as a radius or diameter. To avoid confusion, specify what type of distance is indicated. The laser is responsible for the same parameter. The 532nM green beam is suitable for most measurements.

In addition, the integrity of the instrument and the absence of mechanical damage are checked.

Optic

You need to choose a level taking into account the tasks ahead and the features of future use. They are divided into three classes: high-precision, basic and technical.

Peculiarities:

• An air damper is suitable for outdoor applications, while vibration mode requires the use of a magnetic version.
• To perform tasks in a limited space, the defining parameter should be the smallest sighting distance. For large objects, models with the maximum magnification range of the telescope are preferred.
• Class I or II leveling at construction sites is usually not required, but it should be borne in mind that only high-precision instruments are capable of performing it.
• It is easier to prepare a tool with a compensator for work due to the self-alignment of the sighting axis.

Which is better

The answers to these questions will help you choose the best type of tool for your current tasks.

What basic functions should the level perform?

• The functionality of the bubble level will cover all the problems of household tiling, but it is impossible for them to correctly measure the level of ceilings in different rooms.
• Laser - will save hours of work on marking walls for frames and wallpapers, but is not suitable for determining the correct level of the planes.
• Optical - will support accurate calculations for laying tracks, leveling surfaces, but it will not work to hang shelves inside a kitchen cabinet.
• Hydro - will help to perform a single marking of ceilings, but it is useless for mounting wall frames.

Where will it be used? Indoors, outdoors, or both?

• Most of the electronic models are not designed to work outdoors or in aggressive environments (rain, snow).
• Please note that in addition to the laser level, you will need an outdoor detector, as the beams will not be visible in daylight.

What is the required measurement accuracy?

Industrial lasers and levels have mechanical or digital counters, there is support for recording the angle of inclination in 0.01% increments. For less accurate measurements, basic models of hand tools are selected.

Are additional features needed?

A professional-grade tool, accessories necessary for comfortable work. But the functionality of household and industrial models may not have significant differences.

How to use the building level

Features of use depend on the type of tool. There are no single operating methods.

How to use the hydraulic level

1. Carefully unroll the tubes and fill the instrument with clean, running water through one of the flasks while holding the other one above. Try to fill without stopping so that there are no extra air gaps.
2. Check the correct filling - the tubes should be evenly convex. Drive the rest of the air bubbles with light clicks to the flasks until completely out. If done correctly, the risks will rise to the same height when measured. This can be checked by placing the flasks close to each other.
3. Lock the lids.
4. The next step is to work together. One person holds the flask, and the second goes with a hose to a place or room, the level of which needs to be compared with the current one.
5. When both are in place, the caps are removed from the flasks. It is important to do everything at the same time and at approximately the same height - otherwise there will be overflows.
6. One person holds the flask against a pre-made mark, making sure that the center of the meniscus of the water corresponds to it.
7. The partner carefully raises or lowers the flask, thereby adjusting the level of filling with water.
8. When everything is leveled, a level mark is made by the second participant.

Precautions: avoid kinks and mechanical damage to the hose.

How to use the bubble and magnetic level

• Place the instrument on the surface of the object whose horizontality is to be checked.
• If the air bubble is to the right of the line, the object is tilted down to the left.
• If the bubble is to the left of the line, the object is tilted down to the right.

The vertical level is found by analogy.

Maintenance and care consist in the timely cleaning of the instrument, especially after measurements on wet plaster surfaces.

Precautions are limited to protecting the instrument from bumps and falls.

How to use the laser level

• Place the instrument on a tripod or a flat surface.
• If the model is manual, make sure the bubbles indicate the level. Otherwise, find the screws on the side and adjust them to the required correctness. Self-Leveling - Allow the tool to self-level after installation, typically 30 seconds.
• Turn on the device. The device will emit a beam that reflects on surfaces. Depending on the type of laser level, it can be a dot, a line, or several horizontal or vertical intersections.

If the device has not been used for a long time or has been dropped, calibration will be required. Mounting on a rail or tripod is carried out using a clamp or clamps from the kit.

Precautionary measures:

• do not look at the beam itself, do not direct it at children or animals;
• do not use the tool in the rain;
• do not carry with an unlocked pendulum - many models warn about this with a beep or laser blinking.

How to use the optical level

Before use, check the stability of the tripod. Tighten the mount with the tool. Make sure the foot screws are not too tight on the footing.

Alignment:

• Hold the adjusting screws between your thumb and forefinger and turn them simultaneously in opposite directions. Observe the movement in the graduated flask.
• The air bubble should be centered on the circular level window.
• Centering on a point is carried out by a plumb line mounted on a tripod screw. Then the level is shifted along the head.
• Centering is complete when the plumb bob is above the target point.

Focusing:

• Aim the telescope at a sheet of paper or other light object.
• Tighten the eyepiece until the desired sharpness appears - the sight should be clear.
• With the tube pointed at the supplied rail, adjust the focus with the knob.
• When properly adjusted, the scale of the leveling staff and the crosshair of the sight do not move one after the other.
• After focusing, hold the level on a specific target.

Use the focus knob to add sharpness.

Precautions are the same as for laser models, but additional care must be taken when handling the lens.

Warranty

Standard warranty obligations exclude cases of mechanical damage.

Bubble, magnetic and hydro - related to hand tools. They rarely have warranties longer than 12 months. Most manufacturers do not provide detailed conditions for these types of tools.

Laser - depending on the manufacturer and the category of the tool (household or professional), a guarantee is provided from 1 to 3 years.

Optical - standard warranty period of one year. But the narrowness of the niche forces manufacturers to go to tricks. Some give a guarantee on the tool up to 25 years.

The warranty period can be counted from the date of purchase or shipment. In the second case, it is appropriate to clarify how much time the tool spent in the warehouse.

Faults and repairs

Different parts turn out to be weak links - their set depends on the type of tool.

Bubble and magnetic

The main problem is related to the loss of measurement accuracy.

1. Broken flask with bubble - the readings will no longer be accurate, the error can reach several cm per meter. In budget models, bulb adjustment is not provided - the tool is unsuitable for work with this malfunction. In other cases, tightening the screw fasteners or fixing clips will return the level to the correctness of the readings. During setup, calibration is performed in the same way as when selecting a tool.
2. Bent profile - this happens with bumps and falls. The tool cannot be repaired, it will no longer give accurate readings.
3. Crack in the protective glass of the flask - in models of a collapsible type, the part changes to an analogue. Solid cast levels in this case cannot be repaired.

Minor problems: breakage of protective pads and handles, falling off of magnets are corrected by replacing the obsolete part with a new one.

hydraulic levels

Malfunctions of hydraulic levels are reduced to three types:

1. Broken or cracked hose . Occurs as a result of mechanical damage or freezing of an instrument filled with water. As a temporary measure, you can seal it with a layer of nail polish and wrap it with electrical tape. Complete repair and replacement of the hose is often unprofitable - the costs are comparable to the acquisition of a new hydraulic level.
2. Cracks in flasks - temporary measures are similar to those presented in the previous paragraph, but instead of electrical tape there should be a transparent material in order to see the rizki. Replacement may not be required in mild cases. In serious cases, it is necessary to change, since the defect will affect the accuracy of the instrument.
3. Breakage or loss of protective caps is the simplest case. They can be replaced with plastic soda caps.

Laser

Correction is often impossible to perform independently due to the need for a special tool.

1. pendulum shift - the tool does not work correctly, with deviations in horizontal and vertical measurements. This happens after the device falls or is carried with an unlocked pendulum. Restoration will require an offset adjustment. Such damage is not covered by the warranty.
2. Beam does not burn - the malfunction is caused by a broken wiring or incorrect operation of the batteries. In the first case, you will need to remove the cover of the device and replace the flexible wiring going to the pendulum. In the second case, unclenching and stripping contacts or changing batteries is more often enough. Both options are self-repairable.
3. Instability of readings - as a rule, it will be necessary to change the suspension bearing. The case is rare, but guaranteed in the absence of mechanical damage.
4. Buttons don't work - there are several options for failure, of which only clogging of contacts can be repaired independently. The keyboard may not work as a result of frequent use in dusty environments. Clogged contacts will need to be cleaned mechanically. The procedure can be performed at home.

In difficult cases, the keyboard will need to be replaced. When the coating is membrane, it will not be possible to repair the device without special skills.

Optical

Problems of optical levels are solved systematically or by replacing parts. Repair with improvised tools is often not applicable.

• Sticking compensator - to solve the problem, the standard calibration procedure is performed several times. In case of gross errors, service maintenance of the tool will be required.
• Cracked lens or mirror . Purchase of a similar part is required. The optical lens can be replaced by yourself.
• Adjustment is broken - you need to calibrate the device. The screw fastener is loosened, the plate with the grid is aligned. To do this, the horizontal thread is placed perpendicular to the axis of rotation of the tool, and the vertical thread is set along the plumb line.

Problems in the operation of electronics, serious mechanical damage, repair of the platform or re-tightening of the torsion bars will require the intervention of specialists.

Greetings, dear visitors! I've been thinking about a topic for an article for the last couple of days when I got an email from a reader asking me to talk about building levels. And I thought, what a great idea. After all, where in the repair without a level?

To date, the choice of levels is simply epic. From the simplest water to digital with a built-in laser. What level and for what purposes is needed, as well as by what criteria to choose them - we will find out right now.

Building level: types

The simplest structurally is an ordinary water level, it is also a hydro level. It consists of two plastic, usually cylindrical flasks with a scale, connected to each other by a flexible long hose. The principle of its operation is simple and should be clear to any high school student. It is based on a well-known physical phenomenon - the water level in communicating vessels is always the same.

With the help of such a device, we can easily mark two points that are in the same horizontal plane at a maximum distance equal to the length of the hose. You just need to put marks opposite the boundaries of the water in the flasks.

Such a tool will be indispensable in the construction of a country house, marking ceilings and floors during repairs and similar matters. The lengths of hoses of such levels are in the range of 7 - 25 meters, which is quite a lot. The cost of such a tool, of course, is small, in the region of 150 - 300 rubles.

It is more convenient to work with flasks that are not cylindrical, but rectangular in cross section - they are easier to apply to the surface. The diameter of the tube - the larger, the faster the same level is established in both flasks. As a rule, hydraulic levels have a diameter of 6 - 8 mm.

The next class of instruments is bubble levels or spirit levels. Most of them have a length of 40 - 250 cm. The horizontal and vertical in them are controlled by the position of an air bubble in alcohol, sealed in special transparent flasks. Short spirit levels are needed when laying tiles, installing windows and window sills ...

Long ones - for installing beacons, checking the verticality / horizontality of planes and lines, various markings. Strange as it may seem at first glance, spirit levels can differ in many characteristics, which we will discuss in more detail in the next chapter.

Goniometers and inclinometers are devices that allow you to measure and set the angles between planes, and the slopes of the planes from the horizontal and vertical, respectively. Such devices may look different. Goniometers are also in the form of a flask in a quarter of a circle and in the form of two "rails" connected by a hinge, or whatever it is.

Basically, goniometers and inclinometers are digital instruments, that is, they have an LCD display that displays the angle values. An inclinometer is also often referred to as an electronic or digital level.

I think that goniometers are needed mainly not by builders, but by carpenters. They will also be more useful for inclinometers. In finishing, the inclinometer will be in demand only, perhaps, in tile work, and even then, more for control. Their highest accuracy (usually 0.05 degrees) does not leave the tiler a chance even for the smallest hack. And you will most likely freak out already on the second or third tile))

A colleague of mine who is a tiler recently purchased a Bosch digital inclinometer and confirmed it. But damn, how cool is that Bosch.

There are also various avant-garde types of building levels on sale. For example, pipes. In addition, they also come in different versions. There are devices in the form of “hairpins” that are put on a pipe, there are ordinary bubble devices with a recess for a pipe on the body, and there are generally masterpieces of the avant-garde - “sticks” with five eyes, each of which is set to a certain slope - to make it easier to sewer, you know whether.

laser levels. I already have an article about them, so I will be brief. This is the most technologically advanced type of them (I mean self-levelling). High accuracy, ease of use, huge savings in marking time. Such devices are divided into two large classes: positional and rotary.

Positional ones do not have any moving mechanisms, as a rule, they give out a classic laser cross, or several points.

Rotary lasers give out one point, but it quickly moves 360 degrees due to the rotating base. Such devices are used, for example, by ceiling masters.

Choosing a bubble level

Of course, the most common home repair tools are bubble ones. So what are the most important criteria when choosing a spirit level?

First you need to decide for what kind of work you need it. This will determine the length of the tool. If for a tile, then you cannot do with one level, you will need at least two: short (40 or 60 cm) and long (200 cm). The short one is used constantly to check the level between adjacent tiles. Long - to control the entire plane of the cladding.

If you intend to assemble structures from gypsum boards, plaster, pour a screed, you will definitely need a long spirit level, at least two meters.

The next most important criterion is form.

Often there are levels that in cross section represent a rail. This is not the best choice - such a tool bends very much. Much more powerful than the box-type "stick". And if they have a stiffener inside, then it’s generally great!

The next item is the device of the flasks.

An extremely important feature. In the store, you can see the levels, for example, with the following flasks:

How do you think, in which case the readings of the device will be more accurate? Of course, in the first. The smaller the distance from the boundaries of the bubble to the divisions of the flask, the more accurately the deviation can be determined. Remember this. Also pay attention to the sensitivity of the bubble, it strongly depends on the radius of curvature of the flask. It seems to the eye that the flask has the shape of a cylinder, but this is not entirely true, it is slightly curved, otherwise the slightest deviation from the horizon would “carry away” the bubble to the very edge of the flask.

One more thing can be added here. The verticality flask is often not accessible for a good view, because by attaching the building level to the wall, we will not be able to look at the level readings parallel to it - the head is in the way. So, we will not be able to objectively judge the readings of the device. But there are levels in which a special system of mirrors is built in, and the image of the bulb is “displayed” on the rear end of the level, which is extremely convenient. Such a system has, for example, the Israeli Kapro levels of the Plumbsite series.

The accuracy of the “sticks” for professional use is no worse than 0.5 mm per 1 meter of length; a simpler tool is also suitable for housework, with an error of 1 mm per 1 meter.

Workspace processing. Ideally, they should be processed by a milling cutter. This can be understood by the rough surface(s).

The presence of built-in magnets is also a very important addition to any level. Hung it on the profile and calmly adjust it. Still extremely useful “chips” of spirit levels are slots in the case for easy grip and rubberized pads, which often also serve as shock absorbers in case the instrument falls.

Swivel and adjustable flasks are controversial advantages. Tools that have manual adjustment available instead of a dead mount are more likely to wobble. It is better to take sealed flasks once and for all. The main thing is to carefully check the tool in the store.

The verification procedure is quite simple. Put the level first on the table or counter, look at the readings, remember. Then turn 180 degrees (but keep it in the same place!) and look again. If the position of the bubble is the same, the tool does not lie. You do the same procedure for the vertical, just apply it to the wall already.

In some spirit levels, the flask for horizontal control is recessed into the middle. Personally, this solution seems inconvenient to me, and I do not advise you to purchase such a ***. The flask should be on top, period.

Here is a good video about bubble levels:

Well, he told me everything he knew. Do not buy frank cheap stuff, carefully inspect the tool before buying. This article is over, thanks for reading! And don't forget to subscribe for updates.

When wondering how to choose a building level, any person is aware of the consequences of a wrong decision.

A common type of bubble level is its rectangular modification, which is inexpensive.

After all, any, even the smallest deviation from a flat surface can lead to the most deplorable consequences, up to a complete rework of a just completed repair. Therefore, the question of how to choose a building level should be taken with all care, because this tool can be of several different types, the properties, purpose and price of which can vary significantly.

Currently, the market has a fairly wide range of these construction tools. One of the most common measuring instruments of this type is the bubble level. It consists of a body and a flask filled with a liquid in which an air bubble floats. This level is very simple and at the same time quite accurate and reliable.

What are the types of levels

The principle of operation of the water level.

Bubble levels. The most common type of this level is its rectangular modification. Its length varies widely and can be 2.5 meters. The minimum size is 20 cm. However, occasionally you can find devices of a telescopic design, the length of which reaches 4 meters. Their flasks are made of impact-resistant transparent material. Alcohol is used as a filler.

Some of these tools are equipped with magnets, which makes them much easier to use on steel surfaces. There is also a variety of levels that are used when working with pipes: such tools are usually small in size and have a semicircular recess running along the body. Thanks to it, the device is well kept on the surface of the pipe. These tools have a low price, but versatility is not their strong point, so it is better to choose a different type of level.

water levels. This type of measuring instrument, otherwise known as a hydraulic level, is well suited for measuring the deviations of large horizontal surfaces. It consists of two containers filled with liquid, which are connected by a hose. The main feature of these levels is that their length ranges from 5 to 25 meters, which makes them indispensable when working with extended surfaces and at the same time absolutely useless for use in an apartment.

The principle of operation of the laser level.

They are sensitive to heat, so keep them away from heat sources. It is also necessary to ensure that no air bubbles enter the water while filling the containers, as this significantly affects the readings of this measuring device.

laser levels. Measuring devices of this type are among the most accurate and at the same time the most expensive. Their main advantages are small size and large range, which can reach several tens of meters. They are also best suited for measuring large and extended surfaces, since the laser beam emitted by this instrument can be turned into a plane. In addition, they show themselves perfectly when laying directions. For ease of use, such measuring instruments are equipped with tripods and magnetic suction cups.

Top tools have not one laser beam, but several. They can intersect with each other, facilitating and refining measurements.

This device can definitely be called the best among all levels. It is versatile, accurate, compact and practical. It has only one drawback: its high price.

Choosing a level in the store: what to look for

The type of measuring device largely depends on how large-scale tasks will be solved with it. After all, it is one thing when the level is chosen for frequent use in large-scale construction work, and quite another when it is needed only to level the floor in the apartment.

There is no need to fall under the influence of products of well-known brands and choose the most famous brand, because the main thing in any thing is its quality, and this indicator often has nothing to do with a big name.

How to choose a bubble type building level

Diagram of a bubble level.

First of all, you need to decide for which tasks you need this measuring tool. If you are going to level the walls with it, then you need to choose the maximum length level, but if the question is posed much more modestly and you just need to attach a bookshelf, then the tool, accordingly, should also be smaller.

The air bubble itself should be clearly visible, and the marks on the level flask should be black and there should be several of them. These marks should be very close to each other, forming a kind of scale.

After this verification step, you can proceed to the next one and test the accuracy of the instrument. If the purchase is made in a specialized store, then for sure he has special stands that are specifically designed to test such measuring instruments.

For the test, the device should be placed horizontally and accurately remember the location of the air bubble on the flask scale, then turn the level 180 degrees. If everything is in order with the device, then the bubble will not change its position relative to the scale.

After that, you need to check its work in a vertical plane. For this, an appropriate stand is selected, to which the device is applied. Further, everything happens, as in the previous case: the location of the bubble is remembered, then a 180-degree turn follows. If the bubble remains in its place in this case, it means that the level is made with high quality and you can safely buy it.

In the absence of such a stand in the store, upon arrival home, you need to invite a person who has a level or laser level and use these tools to check the correct operation of the purchased one. If something does not suit you, then there is always the opportunity to return the purchased device back to the store.

What to look for when buying a laser level?

If you have made a choice in favor of a laser measuring device, then when buying, first of all, you should pay attention to its technical characteristics, the main of which are measurement error and range. The accuracy of the laser level must be at least 3 mm for every 10 meters, and the range must be at least 20 meters.

Often, this device comes with special glasses that allow you to better see the laser beam.

In addition, these devices are equipped with two types of lasers, which differ in the color of the beam they emit. Red emitters are the most common, but if possible, it is better to choose an instrument with a green beam, since this color is more visible and contrasting to the human eye. However, levels with a green laser are somewhat more expensive than their "red" counterparts.

It is worth taking a closer look at what is included in the package of the device.

Often it is very diverse and includes both many useful items and those that you can do without.

If, along with the purchase of a laser level, you are going to purchase some kind of addition to it, then be sure to consult with sellers or friends who understand such things in this regard, so that it does not happen that the purchased accessory does not fit your type of device.

Buying a level is a very important step, on which the quality of the upcoming repair directly depends.

How to choose a building level? And which one is better?

The final result of the work of a number of industrial specialists depends on the accuracy of measuring instruments: a builder, a bricklayer, a carpenter, etc. The building level of various modifications is a simple but indispensable tool for any serious team or individual craftsman, which allows you to determine the accuracy of the location of horizontal and vertical surfaces. The history of the appearance of the first spirit level dates back to the second half of the 17th century, and the vertical plumb line is the well-known primitive prototype of later inventions.

The generally accepted classification for building levels:

• Bubble (water level) - with flasks installed in a rigid case filled with liquid, and the presence of a floating air bubble in each flask;
• Laser level - with fast and clear marking by a point of a laser beam of working surfaces;
• Water level (hydrolevel) - the principle of operation is based on Pascal's hydrostatic law and checks the compliance of the planes of horizontal surfaces.

Despite all the obvious innovative advantages of the same laser level, skilled craftsmen never refuse to use a high-quality bubble level - this versatile tool that has stood the test of time.

The main characteristics of the building level

• Measurement accuracy (from 0.3 mm / m, the longer the building level and the heavier it is, the higher the accuracy of its readings);
• Impact resistance. As a rule, levels have a hollow body, but with walls of sufficient thickness;
• Wide resistance to the slightest bending and torsion;
• Measuring flasks with a high degree of transparency and resistance to discoloration, haze, cracking and leakage when exposed to low and high temperatures, as well as ultraviolet rays.

Device

A rigid monolithic, most often rectangular case with a milled bottom edge is made of light and durable materials (aluminum, polystyrene, plastic, wood) with an anti-corrosion coating. In the case, depending on the required accuracy, a certain number of transparent sealed glass flasks (level eyes) are securely fixed with an air bubble floating in a colored alcohol-containing liquid:

• one flask - only for a horizontal guide (180 degrees);
• two - for horizontal (180 degrees) and vertical guides (90 degrees);
• three - for more complex work, with an additional third camera that controls the measurement of the angle of inclination (rigidly fixed at 45 degrees, or swivel - to measure any angle of the controlled surface).

In order to minimize errors in angular vision, limiting lines - risks - are applied on the surface of the measuring flasks. Eyes for checking the position of surfaces of the vertical plane and the angle of inclination have built-in mirror reflectors for simultaneous control of the position of the bubbles.

Plastic plugs at the ends of the level protect the structure in case of accidental drops.

Some level manufacturers also provide additional conveniences: for example, a built-in magnifying lens for more comfortable bubble control, magnetic systems or a fluorescent flask liquid for the possibility of continuing work even in the dark.

The principle of operation of the bubble building level is simple: measuring and adjusting surfaces relative to the horizontal and vertical planes occurs by moving the bubble inside a certain level eye. The result of the correct adjustment will be the presence of the bubble exactly in the middle between the measuring marks of the flask.

Building level. Which is better?

Having decided to purchase a building level, it will not be superfluous to familiarize yourself with some recommendations for choosing it:

1. Flask - must be securely fastened in the body. When buying, it is worth abandoning the level at which the flask is screwed with screws, because of which it can become loose over time. Flasks made of polyacrylic should be chosen, which is stronger than glass and more transparent than plastic.
2. Level length - it is necessary to take into account the type of work to be done, since the larger the working area, the longer the level should be chosen;
3. Defects - the building level is a measuring device, so when buying a tool, you must make sure that there are no factory defects, as well as errors in the readings.

1. Case material - the tool can be made of plastic, metal or wood. The most reliable and durable is, of course, the metal level, inside which there are stiffeners
2. Markup - the best option is to place control strips inside the bubble itself. The divisions applied to the surface of the flask should be clear and located close to each other.

The run-up in the cost of building levels is quite diverse. At the same time, it is not worth asking for a choice of more economic models, especially if you need to use the tool repeatedly. If you have to carry out a thorough repair, then experts strongly recommend purchasing a professional tool. For him, a characteristic difference is the presence of a shock-resistant case with special rubber pads, which, during operation, are able to soften the blows from falls, etc.

In operation, it is better than others, the construction level of the famous German brand "Stabila" has proven itself. For such a tool, on average, you will have to pay from 700 to 1800 rubles. This measuring device is famous for such advantages as:

• high-quality and stable reading of indications (high degree of measurement accuracy);
• good ergonomic characteristics;
• precision in the geometry of the aluminum profile housing.

In addition, this brand also produces magnetic building levels, which make it possible to work with electricity, and are equipped with special slots for marking switches and sockets.

In addition to "Stabila", another good option could be the building level of the company "Shark". The levels of this brand are good because they are not afraid of falls and bumps. Also, good models are produced by Ermak, Bosch or Kapro. For example, the Kapro company constantly updates its models and often introduces the latest innovative solutions, releasing household and professional tools. The models of the German company Bosch are distinguished by high quality. A similar tool with Bosch models is also produced by the Russian company Condtrol, which is more affordable.

In the middle category of such instruments, it is worth highlighting the levels manufactured by Matrix, Brigadier and Stayer, which are distinguished by their high measurement accuracy and optimal cost-to-quality ratio.

However, when buying a building level, a well-known brand should not be a decisive aspect. The main thing is to decide on the type of future work and the frequency of using the tool.

180 degree method

You can check the accuracy of the level in the simplest way, called the 180 degree method:

1. It is necessary to put the building level tightly, without gaps, on a flat horizontal surface and remember the position of the bubble relative to the marks.
2. In the horizontal plane, turn the level 180 degrees and place it clearly on the same area.
3. In a qualitative and accurate level, the position of the bubble should remain the same.

In the same way, you can check the accuracy of the vertical readings.

Round bubble level

This kind of building levels is designed to control only horizontal surfaces and differs somewhat from the usual levels in the design of the body with the same principle of operation. The round level is a sealed hemispherical capsule made of impact-resistant glass with a fixed flask, inside which the position of the bubble is determined by a bounding round line.

The scope of the round bubble level is not only construction work and control of the degree of shrinkage of already rebuilt buildings. Such levels are widely used in photo and video shooting for strict adjustment of the horizontal position of the equipment tripod. The use of round levels is also very common when installing trade or control scales, as well as for constantly monitoring the stable horizontal position of stationary machines, industrial tools and even jewelry surfaces - for example, polishing wheels.

A round bubble level often has the possibility of local attachment to a controlled surface and a very low cost with high measurement accuracy. A knowledgeable person will appreciate this simple and necessary tool.

The ubiquity of levels

Whatever work you have to do (check the correspondence of the vertical and horizontal surfaces of the walls, floor and ceiling; install a washing machine without distortions, hang a bookshelf or a picture) - the simplicity and ease of use of the bubble building level will help you do it quickly and with the highest quality. Even in the presence of a laser level or a plane builder that is more complex in execution and principle of operation, the building level, unchanged in the arsenal of any master, will not remain idle.

proinstrumentinfo.ru

Bubble level is an indispensable tool for construction and repair work of various types. This device helps to create straight lines in any plane, check the necessary slope or angles. The progenitors of building levels are plumb lines and spirit levels, the functions of which they, in fact, perform. Levels are indispensable when laying pipes and various surfaces that are demanding on the angle of inclination. They are used during the installation of equipment that vibrates during operation and is demanding on the evenness of the installation surface. The arrangement of sewers or steps is also not complete without this tool. Building levels are in the arsenal of any master and are a necessary thing in the household, so it is important to know how to choose the right building level.

bubble level design

The building bubble level is a fairly simple but functional design. It is based on a bar made of solid material, in which a number of air ampoules are mounted. Measuring marks are applied to the ampoule, which determine the position of the air inside it. It is this indicator that is the key to the work of the level. When the bubble is exactly in the middle, this means that the surface is perfectly flat. To check inclined surfaces, an indicator of air deviation relative to the center of the ampoule is used.

The main and most important part of the level is an ampoule with a liquid in which air floats. If the integrity of this part is violated, then the entire device is considered unusable. The filling of the ampoule is most often technical alcohol. For ease of use, manufacturers modify the level, some models are equipped with a lens that allows the worker to better see the bubble. To work at night, fluorescent additives are added to the liquid, which help to use the device without additional lighting with their glow. In such improved models, the ampoule with all the additives is called the eye.

Shockproof models have become quite popular. During work at a construction site or during transportation of the device, unpleasant incidents often occur - falls, shakes, mechanical damage that disable the level. Longer models are especially prone to breakage, as their size makes them more likely to fall and makes the impact force stronger than short frame models. At this level, the building price is slightly higher than for conventional models. However, buying a shockproof device is still more profitable than regularly replacing damaged ones with new ones.

The base is equally important in the whole structure. It consists of wooden, plastic or aluminum slats. Wooden planks are made solid, aluminum or plastic hollow. Most often there are levels with an aluminum base. When choosing a device, pay attention to its weight, since the heavier the device, the better its readings. Practitioners among all the modifications distinguish the cruciform design with rubber handles. They call such levels the most convenient and accurate. For working with metal surfaces, it is recommended to use devices equipped with magnets. Another optional but handy addition is a ruler on the long side of the level. Such a modification will help out when carrying out measuring work and eliminate the need to carry a ruler or tape measure.

The simplest and most primitive level model has only one measuring ampoule. But such modifications are quite difficult to find in a modern store. Manufacturers offer a larger range of levels with two or three ampoules. One of the containers is located on the long wide side and is designed to work in a horizontal plane. The second container is located on the narrow short side of the device, perpendicular to the first. It is designed to work in a vertical plane. If there is another container on the bar, then it is also located on the narrow part, but on the reverse side. They fix it at an angle of 45o, and the purpose of this ampoule is to control the operation of the device.

Manufacturers offer bubble levels not only in different versions, but also in various lengths. The shortest standard model has a length of 20 cm, the longest - 3-4 m. This indicator determines the functional purpose of the level. To install various household appliances and perform simple repair tasks in a private house or apartment, it is enough to use small levels. When laying tiles or working with various finishing materials of this type, a length from 40 cm to 1 m is optimal. Long building levels are professional, used when carrying out major construction and repair work. Experts note that the longer the level, the more accurate its readings.

What to look for when buying a bubble level

Building levels are one of the most popular products from manufacturers of cheap and low-quality products. Since this product is used not only by professional builders who know exactly what they need, but also by ordinary people. The manufacturing technology of the building level is not so complicated, but it requires precision and the use of quality materials in order for the device to work properly. Unfortunately, manufacturers of fakes and low-quality goods take advantage of the ignorance of unskilled people in matters of construction and offer low-quality products, the readings of which are not accurate. Trademarks that have already established themselves as responsible manufacturers of building levels:

• Kapro

• Stabila
• Ermak
• Bosch
• Gross Laser
• Shark (Israel)
• Leader

But, even focusing on these names, it is not always possible to buy a high-quality and durable building level. You need to know some of the nuances of choosing this device, as well as be able to determine the required model so as not to overpay extra money for a professional level if it is needed only for small household work.

• To begin with, they are determined with the required length of the tool. To do this, determine the goals and objectives that are set before him. For finishing work and leveling surfaces, you will need a device of great length. For small decorative works - installation of hanging furniture, shelves, switches, paintings, the level of small or medium sizes will suffice. The best option for domestic use is a level 50-60 cm long.

• During the selection, carefully inspect all the glass elements of the device. We are talking about containers with air, which perform the main function. First of all, they must be intact and not have traces of mechanical impact. Next, the strength of their fastening is checked, these parts are fixed tightly and should not stagger or unscrew. There are models with the ability to adjust capacities, the presence of this function is a very controversial point. On the one hand, the adjustment allows you to adjust the failed level, on the other hand, it makes the device more vulnerable to shocks and mechanical stress. Professional builders recommend purchasing levels with a rigid fixation of all containers.
• After examining the fixation of the flask, pay attention to the air itself in it and the strips applied to the surface. All these elements should be clearly visible and located close to each other. The best option is the location of the control strips inside the vial, and not on its outer surface. Since with active use, these marks will quickly be erased.
• The next important factor is the base material of the level. Whether it is made of wood, plastic or metal, it must be heavy and durable. Optimal models with stiffeners located inside. In general, the design and external construction of the levels differs for each manufacturer, but this aspect does not affect the accuracy of the device itself.
• After an external inspection of the level, it must be checked. Specialized stores should always have a stand to test the device, which has a perfectly flat surface. But even if there is no such stand, it is not difficult to check the level in any other place. To do this, it is placed in a horizontal plane and the position of the air bubble is marked. Even if it deviates from the center, this is not scary, since this is not the essence of this check. Then the level is raised, turned 180o and placed exactly in the same place. In this case, the position of the bubble should be at the same mark. If so, then the device is OK.
• The accuracy of the indication of a flat plane without the presence of a verified surface is impossible. But in this situation, it is enough to keep the receipt from the goods and then check the level readings using other devices. For example, for this they use a level or a laser level, or a bubble level, which has already proven its indications. These checks must be carried out even with branded and expensive items, since the technical characteristics and indications of the device are often violated during transportation.

How to set up a bubble level

The bubble level setting is only possible if a model with loose containers is available. The level setting process is quite simple:

• The most even wall in the room is determined, this area should be at eye level, while the corner is located on the left side.

• Stepping back from the corner about 4 cm, they drive in a nail or twist a self-tapping screw. They do this not to the end, but so that 2-3 cm remain on the surface.
• The device is placed with one side on the nail and leaned against the wall, and then adjusted so that the air in the container shows a flat surface. A line is drawn along the edge of the level on the wall.
• Turn the device over and repeat the procedure.

The correctness of the setting is checked by the drawn lines, if they do not go beyond each other, then the device is functioning properly and its readings are accurate. If the marked marks diverged, then proceed as follows:

• On the right side, where the marks end, mark the center point between them.
• The device is placed again on the nail, and the other end is applied to the marked point.
• For convenience, another self-tapping screw is screwed into the mark, or simply hold the level with your hand.
• In the fixed position, the liquid container is adjusted to the required position.

In the same way, the container is adjusted to work in a vertical plane, only the level is pressed against the nail with the long side.

How to work with a bubble level

When working with a building level, it is important to remember that this device has a working surface, with which it is applied to the control area. This area is distinguished by a raw edge or a magnetic insert. In some models, there is no distinction between the work surface and other faces. If you put the device on the other side during use, it will not harm it, but the measurement accuracy will drop. The level is never laid sideways, all measurements made in this way are not correct, since, in fact, a non-existent surface is measured.

To work in a horizontal plane, they are guided by a container in the long side of the level. The device is applied to the surface and a line is marked in which the air is exactly in the center of the ampoule. If there is a deviation to the left, then slightly lower the left edge of the frame or raise the right one. The same is true for deviations to the right.

To work in the vertical plane, they are guided by the container in the narrow edge of the device. For example, if it is necessary to control the quality of the wall finish, then the device is applied to it with the capacity up. If the air moves away from the wall, there is a convex unevenness from below. If the air moves towards the wall, then it means that you need to add a little volume below the level.
