Pay for the use of water in fact is much more profitable than the tariff, because it excludes the payment of considerable sums during your absence from home, as well as during the so-called summer "preventive" periods and during repairs. But many in this regard are beginning to be interested in the question of how to choose a water meter for cold water. This, and also the rules of operation and connection, will be devoted to this article.
Types of cold water meters
There is a classification of water meters, from which they are divided into tachometric and electromagnetic. The first are designed to work with water, the temperature of which does not exceed + 40 ° C. For hot water, there are separate meters that can withstand + 150 ° C. However, there are universal devices.
According to another classification, all meters are divided into volatile and non-volatile. The difference is obvious. Choosing a water meter , you should consider their separation into such groups:
- Vortical - record the frequency of vortices on a part placed in a water stream. As a result, the obtained data reflect the flow rate.
- Electromagnetic - in them the magnetic field is induced in accordance with the speed of the liquid passing through the counter.
- Tachometric - mechanical counters, the action of which is based on placing a turbine or an impeller in the flow of a fluid in a stream.
- Ultrasonic - produce an analysis of the acoustic effect that appears when ultrasound passes through a water flow.
In addition, all meters are divided into household and industrial, used, respectively, at home and in enterprises.
Most often for domestic use choose tachometric or electromagnetic counters of cold water. The first of them, otherwise called the winged ones, in turn are single-jet and multi-jet. Their main difference in the ability of the second type is to divide the flow of water into several jets before passing it through the impeller blades. This allows you to reduce the error in calculating water consumption.
Electromagnetic devices are also popular. Their advantage is in a more precise measurement, which is based on determining the speed and average area of the water flow. Their work does not depend on the temperature of the water, its density and viscosity. So, if you really want to save on paying for water, we advise you to get just such a meter.
Connecting the cold water meter
You can install the water meter yourself. His device is not particularly complicated. The main thing is that before the ball shut-off valve there are no water intake devices. The location of the meter should be as close as possible to the entry of the pipeline into the room. This is done so that it is impossible to crash into the pipe to the meter and consume unaccounted-for water.
The counter design includes:
- a shut-off valve that blocks the water supply, put it on a plastic welded water pipe at a certain distance against the water current;
- a screen filter collecting a fine suspension to prevent clogging of the counter;
- check valve - prevents "unwinding" of readings.
The installed meter must be sealed by an authorized employee of the relevant service. Prepare for his arrival the passport of the device and the verification report. After that you can use the device.

What should I do if the cold water meter does not work?
If the water flow is worse, the filter of the counter is probably clogged. Do not need to disassemble it yourself, ripping off the seal. Do not hesitate to contact a specialist for assistance. And in general, with any breakage of the water meter, independently - cold or hot water , you need to contact the Housing office for qualified and authorized assistance.
