Choice of domestic cold water and hot water meter

Installing a water meter begins with the definition of the functionality, the principle of operation of the device, the accuracy class, the expected regularity and the convenience of taking readings.

The functionality of different models is different, but it is not difficult to buy water meters if you know the basic principle of the difference. In this regard, everything is simple, since the classification is carried out on:

• meters for hot water and cold water;
• universal devices, through which it is possible to simultaneously control the flow of both hot and cold water.

To buy water meters universal type, initially you have to spend a large amount, but during operation they fully pay for themselves. In addition, they allow you to save usable space when choosing an installation location.

According to the principle of operation, devices are distinguished:

• mechanical ones are simple, non-volatile, they are cheap, but they can distort real data during water hammer;
• electronic - high-precision measuring instruments that work flawlessly in any conditions.

Choice of industrial cold water and hot water meter

Devices for controlling the flow of a technical liquid medium in an industrial enterprise must have a higher class of accuracy and reliability. Important selection criteria for industrial water meter are:

• the value of the permissible error - no more than 1-2%;
• sensitivity threshold;
• expected period of intercalibration maintenance;
• operating parameters of pressure in the system;
• installation location and position - horizontal, vertical, availability of free space and ease of access;
• the expected amplitude of the flow and the maximum volume of water flow.

According to the constructive device and the principle of operation, p industrial water meters can be:

• single-jet;
• multi-jet;
• winged;
• turbine;
• combined;
• conjugated.

Purpose and technical characteristics of water meters (water meters)

Dry-running vane meters with nominal diameters Dу 15, 20, 25, 32, 40 mm (hereinafter meters) are designed to measure the volume of network water according to SNiP 2.04.07-86 and drinking water according to GOST 2874-82, flowing in return or supply pipelines of closed and open heat supply systems, cold and hot water supply systems at pressures up to 1.6 MPa (16 kgf / cm2) in the temperature range from +5 to + 50С (cold water) and from + 5 to + 90С (for Du -15 ,20 mm, hot water) or from +5 to +150С (for Dу -25÷40 mm, hot water).
Counters (type VSH, VSHd, VSG, VSGd) have a counting mechanism with roller and pointer indicators showing the measured volume in m3 and its fractions.
Counters of type VSKhd, VSKhd, VST have a counting mechanism with a magnetically controlled contact and give out pulses (when connected to a calculator, recorder or other compatible devices). The price of one impulse, depending on the type of water meter, ranges from 0.001 m3 to 0.1 m3.
The volume of water measured by the meter is determined by the readings of the roller and pointer indicators. The roller pointer (“windows”) shows the measured volume in whole m3, the arrow pointers show fractions of m3.

Technical characteristics of the magnetic contact:
- maximum switching voltage 50V;
- maximum switching current through the contact 100mA;
- contact closure frequency, not more than 1 Hz.

The limits of permissible relative error of industrial water meters should not exceed:
+ 5% in the range of power consumption from Gmin to Gt ;
+ 2% in the range of flow rates from Gt to Gmax inclusive.
Average service life - not less than 12 years.

Placement, installation and operation of the water meter (water meter)

Water meters are installed in heated rooms or special pavilions with an ambient temperature of +5 to +50C, and a relative humidity of not more than 80%. The instruments must be freely accessible for inspection at any time of the year. The place of installation must guarantee the operation of the device without possible mechanical damage. Installation of water meters in flooded, cold rooms at a temperature of less than 5C, and in rooms with a humidity of more than 80% is not allowed.

When installing a water meter, the following mandatory conditions must be met:

A) The water meter is mounted only on a horizontal section of the pipeline with the dial up - H, while the meter DN15, 20 mm operates in the flow range of class B, when installing water meters with DN15, 20 mm on a vertical section or the dial parallel to the wall - V, it operates in the flow range corresponding to class A (see technical data).
b) Installation is carried out in such a way that the water meter is always filled with water;
c) When installing a water meter after taps, valves, adapters, filters and other devices, it is necessary to provide a straight section of pipelines with a length of at least 5D in front of it, and at least 1D behind the meter (where D is the diameter of the pipeline). A straight section of the pipeline in front of the water meter with DN = 15-40 mm is not required if it is mounted with a set of special design connectors supplied by the manufacturer that stabilize the water flow. If the installation conditions are violated, an additional error appears.
d) In case of repair or replacement of the water meter in front of the straight section before the device and after the direct section of the pipeline after the device, shut-off valves (valves, gate valves, valves), as well as drains for emptying the disconnected section, which are mounted outside the area of ​​\u200b\u200bstraight sections, are installed.
e) Before the water meter for DN = 15-40 mm, but after the shut-off valves outside the zone of the straight section of the pipeline; as well as after the meter, when installing it on the heat supply return pipeline, it is recommended to install water filters before the shut-off valves.
f) It is not allowed to install a water meter at a distance of less than 2 meters from devices that create a powerful magnetic field around them (for example, power transformers).
