How to install a gas meter in the apartment yourself. Installation of a gas meter in an apartment: safety rules, installation, requirements

Gas metering allows you to understand who and for what you pay monthly. If you have not installed a gas meter, you will pay for each family member who is registered in this living space, regardless of such a factor, whether you use the entire limited amount of gas or not. If you install a gas meter, you will only pay for the energy used. Consumer experience shows that monthly payments for the use of gas after the installation of the meter will be reduced by 30 - 50%. Today we’ll talk about how to install a gas meter yourself and how to choose the right device.

Purpose of gas meters

In the private sector today, a large number of houses are heated by gas. Tariffs for this type of energy are rapidly increasing in our country. In order to keep accurate records of this resource, you need to know the amount of gas consumed and control its costs. For this, there are special gas meters.

On average, 1000 are consumed per month. cubic meters gas, depending on the quadrature of the heated room. In the warm season, gas consumption is minimized, but in winter time there will be impressive amounts of payment, which in general makes necessary installation gas meter to save resources.

Installing a gas meter in the homes of owners of a gas meter is not a luxury, but a real necessity. With the help of a gas meter, the amount of liquefied or natural gas consumed is measured. That is, with the help of this apparatus, it is possible to keep records of energy resources, as well as stimulate consumers to save them.

The measured medium of gas meters is butane, propane, natural gas, as well as other non-aggressive and in their own way chemical composition inhomogeneous gases. Gas consumption is most often measured in cubic meters per hour. For example, the cost of purchasing the device itself and the cost of installing a gas meter on average pay off within a year.

Such a gas meter can be installed in the gasified room itself or in the room of the gasified building, if it has ventilation. Also, the installation of meters is allowed in a room that is adjacent to the gasified one, and if there is an opening between them.

The meter should be far away from the zone of moisture and heat release. It should be located in a well ventilated area. Undesirable installation sites are niches, as well as areas that do not receive Fresh air. If the device is installed outside the building, then it must be under a canopy or in a cabinet, that is, sheltered from external influences.

Varieties of gas meters

The need to install a gas meter was appreciated by large enterprises and individual individuals. Today there are four types of gas meters: vortex and turbine flow meters, rotary and membrane.
The principle of operation of a diaphragm (chamber, membrane) counter is based on the fact that the gas is divided into volume fractions using various converting elements, and then they are cyclically summed.

The advantage of diaphragm meters: low cost, easy to manufacture, as well as a fairly accurate count even with a small amount of gas. But such meters practically do not tolerate both permanent and temporary overloads.

A rotary meter is a chamber gas meter, which uses eight-shaped rotors as a converting element. A rotary counter, with small overall dimensions and weight, has a relatively high transmittance, it also withstands certain overloads and is durable. A rotary gas meter is made of expensive materials, requires careful fitting of parts, and is more expensive than other meters.

Turbine gas meters are gas meters in which the turbine wheel is driven into rotation by the action of a gas flow, and the number of revolutions is directly proportional to the volume of gas flowing through it. The counting mechanisms of the turbine gas meter have recently been equipped with modems, with the help of which all readings are transmitted to the servers of the inspection services.

Such a counter as a vortex counter uses the calculation of the frequency of occurrence of vortices near the body, which is flowed around by a gas flow, the frequency of which is proportional to the flow velocity. Hot-wire or piezoelectric detector sensors are used to detect vortices. The following advantages of vortex meters are distinguished: rather high maximum flow rates relative to the diameter, wide measurement limit, especially at high pressure, low sensitivity to contamination of this measured medium. Also, this meter needs an external power supply.

Calculation of gas consumption

Gas meters for maximum bandwidth conditionally divided into industrial, household and household. Most often, it is practiced to install household gas meters with a capacity of 1 - 6 cubic meters per hour in offices, apartments, houses, as well as small furnaces for metering gas consumption. These are usually membrane (diaphragm, chamber), less often small rotary, ultrasonic, jet devices.

Apparatus such as domestic, with a maximum capacity of 10 - 40 cubic meters per hour, are used to account for gas consumption by technological installations, small boilers, etc. These are usually larger membrane (diaphragm, chamber), jet, rotary , ultrasonic gas meters.

Mostly industrial devices are used with a maximum throughput of more than 40 cubic meters per hour at the nodes of large consumers, such as industrial and agricultural enterprises, gas boiler houses, main networks (narrowing devices, ultrasonic, turbine, vortex gas meters), as well as metering stations of gas distribution networks (turbine, rotary, jet, ultrasonic, vortex gas meters).

Basically, the following types of markings for gas meters are distinguished:

• G-16 - throughput is from 16 to 25 cubic meters of gas;
• G-10 - 10 - 16 cu. meters;
• G-6 - 6 - 10 cu. meters;
• G-4 - 4 - 6 cu. meters;
• G-2.5 - approximately 2.5 - 4 cu. meters;
• G-1.6 - about 1.6 - 2.5 cu. meters.

To install a gas meter in an apartment, you need to choose a device depending on the number of gas appliances used. If a gas stove with 2 burners is used in the house, which consumes approximately 1 cu. meters per hour, then you can get by with a device marked G-1.6. In order to calculate the total fuel consumption, you need to look at the passport of each device that uses gas. There are left and right counters, depending on the direction of the passage of the energy carrier, and the choice of a certain type depends on the location of the stove and pipe in the kitchen.

The principle of operation of the gas meter

The gas meter consists of sealed housing, which has a built-in measuring mechanism, as well as a reading device. The principle of operation of a diaphragm gas metering apparatus based on the energy taken from the incoming gas is based. Alternate displacement of gas is performed from the working chambers when the diaphragms are moved. The crank mechanism converts the translational movement of the diaphragms into rotational, which is transmitted through the clutch to the reading device.

The design of the meters has a device with a bimetallic temperature compensator, which makes adjustments when the gas temperature affects the meter readings. Such a compensator, at gas temperatures that are different from the norm, changes the volumes of the measuring chambers and thereby the volume of consumed gas leads to standard conditions.

Do-it-yourself gas meter installation

The best option is to install a common house gas meter. Of course, the price of such a gas meter is much higher, but the costs will be much less than installing an individual gas meter. If you do not have such an opportunity to install a gas meter for the whole house, read on.

If you only have a stove in use, it makes no sense to install a household meter at all. The payback period when the device is operated only with a gas stove can take up to 5 years. But the presence of a water heater and a gas stove is already a good option. Most the best solution- if you have a boiler, water heater and stove. The payback time of the meter will depend on the available gas equipment.

Submitting an application to the gas organization

We must not forget that gas equipment is a hazardous product. It follows from this that only a specialist who has certification should be engaged in the installation of the meter. Gas is a very dangerous material for non-professional people to deal with. Thus, self-installation is not welcome.

The gas supply organization controls the entire installation process so that there are no problems later during operation. The sealing of meters is carried out exclusively by those organizations that are allowed by law and that have special permits and licenses. After the work is completed, you should be given an act of successful "operation" in your hands.

The very first step is to submit an application for the installation of the device to the regional gas organization. Before installing the meter, you need to consult with a specialist about gas consumption in the apartment in order to select a device of the required throughput and the appropriate class.

In accordance with the received specifications and requirements for the installation of gas meters, you need to purchase the device. Household gas meters intended for apartments and residential buildings differ from each other, first of all, by their “nominal value”, that is, the amount of energy passed per unit of time. If the apartment is equipped only with a gas stove, then a device that passes two and a half cubic meters of gas per hour is suitable.

Gas meter installation project

When installing a gas meter, one more feature must be taken into account. Such is the development of a scheme for installing a gas meter and gas equipment. In this project, the bending radii of the pipe should be determined, the distance from the meter to the heat source, as well as some other parameters, should be taken into account. Quite often this provision is not fulfilled, but in vain!

To choose the installation location of the meter, you need to be guided by the following considerations:

• The meter is installed at a height of 1.6 meters.
• The passport of the device must indicate the distance from the gas equipment to the gas meter. If there is no such item, then the distance should be from a household stove or heating equipment(boiler, heat generator) not less than 0.8 meters. From the restaurant, cooking and heating stove, as well as the digester to the counter, the distance must be at least 1 meter.
• The gap between the meter and the wall should be at least 3-5 centimeters in order to avoid corrosion damage to the meter.
• The room itself must have natural ventilation, while it is undesirable to install the device in a stagnant zone.
• If the meter is installed inside the room, then it should be placed away from objects that radiate heat and moisture.
• The rules for installing gas meters still allow you to put the device in open form outside the building, but still, to extend the service life and safety, the device should be installed under a canopy in a cabinet or other structure, but it must necessarily have doors with locks and natural ventilation. It is advisable to install metering devices under the openings in the wall.

Installation of a gas meter

After contacting the gas service, an invoice will be drawn up for you, after payment of which a master will come to you and make sure to install a gas meter. At the entrance to the gas meter from gas pipe in any case, you need to install a special dust filter. The device can easily break down if such a filter is not installed.

Remember that during the installation of the meter, the documents already available for your gas equipment (gasification project, passport) are checked, so that there are no troubles, you need to put them in order in advance. After installation, you must immediately issue a passport for the gas meter. It often happens that the master in the passport puts a mark on the spot, but sometimes you need to contact the gas service. Next, the counter is sealed.

Specialist, management company, after installing the meters in two copies, transfers to the client an agreement for the installation of a metering device, then an act of acceptance of the work performed is signed, also in two copies, an act of putting the device into operation in three copies, and also in three copies an agreement for Maintenance metering device.

After that, the owner of the apartment goes to the DEZ or HOA and provides an act of commissioning, and then concludes an agreement to pay for the resource for the gas meter. It will be necessary to report the gas meter readings to the information and settlement center once a month, after which you will be informed of the amount of payment.

One of important points The use of the counter is to check the machine for correct operation. The manager of the company carries out an initial check, and then the owner of the gas meter does this, calling once every certain number of years (such data is indicated in the passport of the device) a representative of the Center for Standardization and Metrology, who checks the devices and makes the appropriate marks in the passport of the device.

If you are tired of the average gas consumption rates “in the whole country”, and you want to save your honestly earned personal funds, then it's time to take care of installing a gas meter. Like any metering device, a gas meter and its installation have characteristic features.

Strict controller - gas meter

A metering device that is designed to measure the amount of gas flowing through a gas pipeline is a household gas meter. Therefore, the meter is used for apartments and private houses equipped with mini furnaces. In most cases, gas communications and meters are installed for a significant period of operation.

Before choosing and installing a meter in an apartment, it is necessary to consider the safety of its performance and durability. The installation of a gas meter is a regulated activity that is controlled by the relevant authorities. The process of installing a gas meter will begin with a visit to just such coordinating organizations. So the time has come...

The principle of operation of gas meters

As you know, the invisible gas, thanks to which we are able to cook food, is a mixture consisting of certain components with given properties. Therefore, the process of calculating the gas mixture is built according to the laws of physics.
According to the principle of operation, gas meters are divided into groups:
turbine
vortex
rotary
membrane.

For household needs of the population, gas meters of rotational and membrane type are used.
Rotary gas meter is based on the principle of counting the volume of gas passed in proportion to the number of revolutions of the rotor. The portion of gas cut off between the wall of the measuring chamber and the rotor is a quantitative unit. When the rotor rotates through a mechanical transmission, this information is transmitted to the counting mechanism, where the amount of gas that has passed is actually accumulated. The quantitative value of the count is the value of Qmax. For domestic sector Qmax. is from 4 to 10 m3/h.

Principle of operation membrane counter based on the short-term movement of thin mobile membranes. IN gas chambers in the presence of a gas mixture in the device, these membranes move, which, through a mechanical transmission, activates the counting mechanism. Membrane type meters are used for maximum gas flow rates Qmax. from 2.5 to 100 m3/h.
The device of a household gas meter is shown in the video.

General classification of accounting gas devices based on the amount of gas consumed. So the gas consumption of an average stove with 4 burners is 1.56 m³ / h, for a gas column - 2.50 m³ / h.
Gas meters of industrial production are produced taking into account the direction of gas flow. Therefore, when purchasing a gas meter for an apartment, it is necessary to take into account the placement of the gas pipeline and stove in the kitchen.

Rules for installing the meter

Before starting installation work, you must contact the city gas utility. Such a procedure is necessary in order to find out all the conditions and details of installing the meter. You can deal with the purchase of a gas meter on your own by connecting a familiar professional specialist.

As an alternative - the purchase of a meter in the gas industry and its installation by the specialists of the economy. In this case, you can even save some money on the purchase of a meter, because gas industry specialists are interested in this purchase.
Installation of a gas meter is carried out only by specialists who have licensed rights to install this type of equipment. Are you looking forward to when the features of the national installation of meters will come?

Installation features will come immediately after you submit an application to Gorgaz. So, the next step in installing the meter will be submitting an application to the city gas industry. A photocopy is attached to the application, certified by a personal signature and date of filing. technical passport on the living space and a certificate of no energy debt for the current month of service. After submitting the application and registering the meter, you will be assigned a day for the visit of a gas management specialist. A visit to a specialist should determine the technical feasibility of subsequent installation of the meter. In addition to such a survey, you will be given the price of installation.

On the appointed day, the installation and installation of the gas meter will be carried out by specialists from the gas industry.
Installation of equipment depends on the design features of a particular model and the placement of the gas pipeline in the kitchen.

Features of installation of gas meters

It is allowed to lay a gas pipeline at the level of the connecting fitting. The shut-off valve can be located on the side of the stove at a distance of 200 mm. In the case of upper wiring, the shut-off valve is installed on the descent. The gas meter must be visible and located away from the stove.

Permissible installation height 1.5 m from the floor. Installation and installation of gas appliances is regulated by SNiP 42-01-2002 and SP 42-101-2003. According to paragraph 6.47 of SP 42-101-2003, the installation of meters is provided based on the conditions for the convenience of their installation, maintenance and repair.

Gas meters can be installed with rubber sleeves. Rubber sleeves must not fall into the heating zone of the appliance. The installation of meters provides for subsequent convenient conditions for maintenance or repair.

Such conditions are regulated by the operational documentation of the manufacturer. It is recommended to install meters outside the zone of moisture and heat release in well-ventilated places.

And we have gas in our apartment, and you

After the successful completion of the installation work, the owner of the apartment and the newly installed meter receives the Installation Certificate and the settlement document intended for sealing the meter. And here again the "features" of installing gas meters arise: you will not be able to start using gas until the seals are installed.

Installation of seals on the counter is carried out by specialists. Payment for gas, according to the meter readings, is made after the installation of seals. The service life of the counter depends on its brand. After 10-15 years, you will have to take the meter for another verification.

Of course, you will be fabulously lucky if gas meters have been installed and registered earlier. In this case, the replacement of the gas meter can be omitted. If the meter meets all the parameters and is in working condition, then it will be enough to conclude an agreement with the organization. However, all the formalities of the correct execution of the documentation will have to be observed.

And now, finally, two weeks of waiting are over, and you are the proud owner of a gas meter in your apartment. The membranes and rotors of the meters are waiting for the first portion of the explosive mixture called "gas".

Measuring the amount of gas used can reduce your monthly billing costs utilities. The absence of a meter in a house or apartment obliges consumers to pay for services at a single tariff - for the volume of gas that, according to statistics, one person spends for a certain period. From this article you can find out the rules in the apartment and the basic requirements for installation.

Criterias of choice

To date, several types of meters are used: membrane (diaphragm), turbine, rotary, and vortex, so there really is plenty to choose from.

In Russia, membrane-type devices are most often installed on domestic gas networks. This equipment is equipped with an elastic membrane. The main advantage of these devices is reliability, simplicity of design and relatively small size. Electronic meters are more accurate due to built-in monitoring sensors.

They are also divided by how much gas they consume in one hour. This parameter is determined by studying technical parameters all gas appliances located in the apartment. Consumption of a classic four-burner gas stove averages 1.56 m 3 /hour, columns - 2.5 m 3 /hour. Summing up the total consumption will allow you to find out the power of the required meter.

When choosing a rotary, volumetric or electronic gas meter, you should pay attention to the fact that the gas supply can be carried out both on the left and on the right. When buying, it is important to consider this point.

It is imperative that when buying, you need to check the date of manufacture of the selected model, since the interval between verifications is determined not by the day of installation, but by the date of issue. If more time has passed after the factory check than is required before the next test, then some difficulties with the service life may arise.

Marking

The meter marking indicates the amount of gas consumed:

• Devices marked G1.6 are capable of passing and counting volumes up to 2.5 m 3 / hour.
• G2.5 - up to 4 m 3 / hour.
• G4 - up to 6 m 3 / hour.

There is also more powerful equipment, for example, a gas meter SGMN G6 or G10. These devices are characterized according to the same principle.

The testing interval for old-style equipment (SG marking) is 5 years. While a modern electronic gas meter can operate on average 12 years.

Installation Requirements

The gas meter is a rather complex device; certain requirements must be met during its installation. Included with each should be a passport - a document that contains information about the device and the requirements for its installation and operation.

Exist General requirements and rules for installing a gas meter in an apartment:

• Distance from the device to a floor surface - 1600 mm.
• The distance from the heating boiler or gas stove to the appliance is 800 mm.

In addition, this equipment can be installed not only indoors, but also from the side of the street. In the latter case, it is desirable to protect the meter from direct exposure to sunlight, strong temperature changes, and moisture. Such impacts can significantly reduce the operational life of the meter.

When installing individual devices in the passport, they may indicate additional ones in the apartment, which apply to a specific model and differ from the general requirements.

Required documents

For installation, you will need the following approximate list of documents:

• Ownership of the premises where the metering device will be installed.
• Identification.
• Passport for equipment.
• If the device has not yet been purchased - passports for all gas equipment installed in the room (boiler, stove, etc.), to determine the power, load when choosing a meter.
• Plan of a dwelling house.

This is an approximate list of documents, so when you still decide on the installation of a gas meter, it is advisable to check the exact list on the spot.

Installation instructions

Rules for installing a gas meter in an apartment:

Basic installation requirements

Despite the fact that gas meters in private house are not installed by the consumer, it is necessary to familiarize yourself with the basic requirements for installation. And in addition to the above rules, there are others.

Installation of gas meters - the law!

In accordance with Law No. 261-FZ "On Increasing Energy Efficiency and Energy Saving ...", adopted in 2009, gas meters must be installed in every home. And there is nothing wrong and terrible in this, because we have to pay for the amount consumed, and not for the norm, which is determined by the number of registered people.

After all, in different apartments and at home, energy consumption is different, some have more, and some have less. Most of the owners who installed metering devices felt the savings on their wallet.

Article 13, paragraph 5.1. states that the installation of gas meters (law No. 261-FZ) must be carried out by the owners apartment buildings until January 1, 2015.

Installation cost

In principle, any metering device is the property of the person who owns the apartment. Accordingly, the customer must reimburse not only the cost of the meter, but also the installation work.

There are a number of factors that can affect the overall cost. Consider them:

• For whose money the device will be purchased.
• Need to fulfill welding work or its absence.
• The length of communications for the output of the meter.
• The number of devices in the apartment that consume gas (boiler, gas stove, water heater).

If we talk about a specific cost, then installing a gas meter with one gas stove will cost an average of 4000-5000 rubles.

Here step-by-step instruction with a list of what needs to be done in order to legally and officially install gas meters at home:

How to choose a gas meter in an apartment?

The gas service of each region or city offers to purchase a meter directly from them or in their specialized store. Is it worth it to refuse the proposed options and look for your own? Will it be possible to wind up evidence on it?

In principle, there is no clear regulation on where to buy household gas meters. If you know where you can buy a device cheaper or more reliable - this is only your right. However, be sure to contact the master before buying - there is a possibility that the gas service of this region only works with a particular type of meter, and then the choice is small. But it’s better not to save money by trying to wind up the readings of the device. Modern controllers know such "chips" better than users, and will quickly notice the discrepancy.

Gas metering by eye has never been beneficial to tenants, but today it is a necessity, since these devices allow you to save more than just. They are already forcing them to save money, because since January 1, 2015, their installation has become mandatory procedure. Despite some difficulties, we will go through the procedure, install the meter and start saving.

Law on gas meters

With the law, as always, full order. On December 29, 2014, the law on the mandatory installation of fuel metering devices in apartments was amended. Before this period, in all dwellings, including:

• emergency buildings;
• objects for demolition, which was to be carried out before 2013;
• houses and apartments that are subject to major restoration;
• in all dwellings where electricity consumption is within five kilowatts;
• in houses where heat consumption is not more than two tenths of gigacalories per hour,
• and also in apartments that consume less than two cubic meters of gas, its presence was mandatory.

Term

Now, from January 1, all this does not apply to those objects that use gas stoves with a maximum consumption according to the passport no more than 1.3 cubic meters per hour. This suggests that now again it is not necessary to install this meter. But only if we use gas only for cooking. So, again from the beginning. Nevertheless, in order not to wait for new innovations, it is still worth installing it, so as not to pay more at least. It is logical, rational and legal. The binding has now been cancelled.

In a word, if we do not live in an apartment with a column, no one forces us to take into account consumption, for those who do not heat water and heat their homes with gas, it is still worth installing it. Although this will require a certain amount of time and financial investments, but the game should be worth the candle. True, gas services with suspicious persistence remind of this, which suggests that not only the consumer will benefit from metering with the help of devices.

Not surprising, because the installation is carried out only by the hands of the gas distribution organization of a particular region. Otherwise, if the consumer shows distrust or doubts the quality of the services of the gas office, third-party performers coordinate the work with a special service.

The documents

First - buy a counter. Moreover, before buying, coordinate the model of the accounting device with the gas office and check that this device is included in State Register measuring instruments. There is some truth in this, since each device has a resource, after passing which, it is subject to verification. The greater the resource, the less often verification in the gas office. These terms are indicated in the device passport. As a rule, it is within 5-10 years. So we got to the documents that are necessary to provide to the gas office to apply for the installation of a meter:

• civil passport of the owner of the property;
• subscription book;
• a standard project for gasification of a house or an approved apartment plan;
• documents that come with the device;
• contract for the maintenance of gas appliances.

Cost and scheme

Work on inserting the device into the pipe is paid by the applicant, so you should not hope for serious benefits. Gazprom provides a 5% discount on work if you pay at a time. Prices for work are summarized in the table and they are valid throughout 2015.

Meter installation works include:

• acceptance of the application;
• sketch preparation;
• elaboration of contracts on the basis of specifications;
• disconnection of gas supply during events;
• wiring removal;
• dismantling of old equipment;
• threading, pressure testing of gas pipelines;
• launching and testing the integrity and tightness of connections.

After that, the execution of documents on the work is carried out. In this case, the consumer schema is not concerned. Everything is done by Gorgaz.

Privileges

As for benefits for payment for work, the subscriber pays on his own, after which he submits an application for reimbursement of funds, attaching a bank account number to the application. After considering the application, the commission pays up to 70% of the funds spent to the specified account, but only if the price did not exceed 6600 rubles. Benefits are used by pensioners, apply at the place of residence, and free installation of meters is not provided.
