Payment for water supply often reaches 20% of the total cost of utility bills. And it does not matter if its owner lives in the apartment. You will need to pay for as many people as it is prescribed in it.
Owners claim that they use significantly less water than indicated on payment receipts. In different cities, Vodokanal loses up to 30% of the resource in losses. Only the installation of a water meter will help, which will make it possible to pay only for the used water.

Meters for water are used in many places: to account for the amount of water used in various industrial organizations, and in the communal sphere. They help monitor the use of wastewater and mains water, and the use of heated coolant in the heating system.
Before buying a water meter, you need to understand their systematization. Such devices are divided into devices for accounting for hot and cold water. The principle of operation of such devices is one, the difference is only in the materials used in the manufacture.
A cold water meter is used to work with temperatures not exceeding 40 degrees. Devices for hot water can operate at temperatures up to 150 degrees. There are universal mechanisms that are used to account for the costs of both cold and heated water.
Another type of classification divides all such devices into non-volatile and volatile devices. Some of them do not require the use of power sources. Others function only when connected to the mains and stop working when there is a power outage.
Varieties
When determining which meter is best to purchase, keep in mind that they are divided into 4 types according to the principle of operation:
Whirlwind
The frequency of the vortices formed on a special element located in the fluid flow and taking into account its speed is fixed.
Electromagnetic
The flow rate is recorded by inducing a magnetic field.
Tachometric
A water meter on a mechanical basis, with an impeller or impeller in a stream of water.
Ultrasonic
Consider the sound effect resulting from the passage of ultrasonic waves through a moving fluid stream.
Domestic devices are used in private houses and apartments, and industrial devices are installed in various enterprises. For installation in apartments, tachometric and electromagnetic devices are mainly used.
Tachometric counters are small in size, low price, measurement accuracy and reliability. The device works for at least 12 years, but with mandatory verification after a certain period of time.
Vane metering devices are:
Single jet
This counter counts the number of revolutions of a turbine rotating in a fluid stream in a pipeline. The counting mechanism is reliably protected from water, for this reason the measurements remain true for a long period.
The advantages of this device include the ability to use a pulse output, which makes it possible to remotely read data. Features of the device additionally allow you to install a module of protection against magnetic waves.
Multi-jet
The main difference is in the division of the total water flow to the impeller into several separate jets. That allows to increase the accuracy of water flow measurements. The positive qualities of such mechanisms include ease of installation and dismantling, this allows for mandatory verification, remove only the upper element of the device. It is possible to use a pulse output.
Turbine devices are used for pipes with diameters in the range of 50-200 mm, and winged ones are not more than 40 mm. Combined meters combine turbine and wing elements, they are used in water conduits with a large pressure drop.
The operation of electromagnetic devices is independent of changes in viscosity, temperature, and fluid density. For this reason, they are chosen quite often, but one must take into account the fact that both the physical and chemical characteristics of the liquid, although slightly, affect the accuracy of the device.
The choice of meter
What is better to buy and how to find the most suitable model for your home? Any owner needs to choose one water meter from many models. Among the equipment offered, buyers love the products of German manufacturers.
But the distinction between domestic and imported goods is most often minimal - domestic devices for metering used water are most often manufactured in joint organizations.
For a specialist installing the device, its technical characteristics are important - allowable pressure and operating temperature. When purchasing a meter, you need to take into account the area of accounting, the sensitivity limit of the device and the possibility of pressure loss.
The best models of domestic water meters
There are many models of water meters on the market that differ in cost, life and characteristics. But not all water meters are suitable for an apartment, it is better to produce them at the manufacturer and price.
Experts advise the use of products from such manufacturers for installation in the apartment:
Ryazan Scientific Production Enterprise "Pulsar"
Meter
Mytishchi enterprise "TeploVodomer"
"Multisystem"
"Beregun"
All of these products have a bore diameter of 15 mm and a throughput of 1.5 m3/ h
Price for metering devices
This parameter of water meters for an apartment or house ranges from 400-3000 r. It is not worthwhile to compare domestic metering devices in detail, since their parameters are very similar.
Foreign manufacturers of water meters are mainly represented by products from Italy and Germany - Bmeters, Minomiz, Zenner, Minol. The price of these products is slightly higher than our firms 1000 to 7000 p.
Water meters manufactured in Russia differ from imported devices in a shorter service life. In most cases, water meters manufactured in our country are guaranteed to last 3-4 years, and about 5-6 years brought from abroad.
Self-installation of the device
What you need to install:
- water meter with the necessary parameters;
- 2 filters;
- check valves that allow fluid to pass only one way;
- keys up to 30 mm;
- submarine hoses of the required length;
- scissors, hacksaw, grinder;
- connecting and adapter couplings;
- tow or FUM tape;
Most often, the water meter is installed on the drive outgoing from the main riser. In order not to shut off water and simplify repairs in an emergency, it is better to install the device after the inlet valve. The rules provide for the replacement of old valves, without blocking the common riser, this work cannot be performed.
It is necessary to mount the cleaning filter on the external thread, there is an arrow on it, indicating in which direction the water should flow, usually with a protrusion from the tap. FUM tape or tow are necessary to seal the thread at the connection of individual elements. It is necessary to lay the seal in a clockwise direction.
After that, you can install a water meter, it is attached to the assembled fittings by installing a gasket. As when installing the filter, the water meter must be installed, focusing on the arrow indicating which direction the water should move. On the other hand, 2 nozzles are attached to the water meter and joined with a check valve, the arrow on which should be directed from the nut.
Reviews
- Dmitriev Victor. “I never imagined that there were so many models of water meters on the market, I bought French ones with an impeller from Flumberger. They are of the same model, they have been standing in my house since 2011 both in hot and in cold water. We made several calibrations; there are no complaints about the operation of the devices. Yes, for the first time I checked them on my own, installing a capacious container, and the tuft fit into the tuft. I don’t trust electromagnetic devices, can I turn off the power to the house, and the water meter will continue to wind up, or may the water stop flowing? This question is completely incomprehensible. ”
- Yurchenko Vasilisa. “In my opinion, the most important thing for the owner of the house is that after placing the water meter and the subsequent installation of the seal, you must carefully protect it! If you suddenly accidentally, cleaning up or wiping the dust, or a randomly playing child pulls this interesting little thing, it will damaged, the service provider can recalculate the payment according to the stipulated norm of water consumption (and not for actually spent water). ”
- Vasiliev Michael. “In general, everything is somehow strange, the work of taking readings from a water meter can be automated and information can be received directly to the server. In emergency situations with the power system, apartment owners certainly should not lose money and be responsible. ”
- Yuryeva Natalia. “The information I read was very useful. Thank you for your concern! In my opinion, and recent experience, with the help of such an instruction, everyone is able not only to control the quality of the work of installers, but also to install a water meter with their own hands. THANKS! ”
