Water meters Norma: specifications and maintenance. Water meters how to choose Water meter norm svk 15g passport

Currently, there are a fairly large number of models of individual water meters on the market, which may differ from each other in different characteristics. Many homeowners face a burning question: ?

Water meter designs

Despite all the variety of water meters developed by engineers, the vast majority of private households use mechanical meters. They are based on a wheel with wings that rotates under the flow of water. Information about the number of revolutions is transmitted to the counting unit, which is a mechanical dial with digits.

Consider the most popular models of individual water meters sold on the domestic market. In the line of offered models, according to the information of the Yandex Market system, the counter for hot water model "Norma SVK-15 G". It will cost you 329 rubles. The maximum price has an apartment meter from the company "Valtek" model VLF-20U 105 2.5. Its cost is 1125 rubles.

Hot water meter "Norma SVK-15 G"

The counter of the Russian production from the Norma company of the SVK-15 G model is designed on vane technology. It can take into account the volume of flowing water in the range of 5-90 degrees, that is, it is suitable for measuring the flow in pipes of both hot and cold water supply.

Thanks to the brass body, water pipes from any material can be connected to the meter. Brass prevents electrochemical corrosion.

The price of the device is 329 rubles.

The next Russian-made water meter from a Kazan company is also a universal device for hot and cold water(5-90 degrees) and withstands pressure in the pipeline up to 1 MPa.

For 367 rubles you will receive not only a counter, but also a connecting kit.

This model comes without connecting fittings and costs 464 rubles. The meter is designed with protection against magnetic influence, it can measure the flows of hot and cold water, it will work on these pipelines without verification for 6 years. The company gives a warranty period of 4 years. Device length 10.1 cm.

The PULSE brass water meter measures the flow of water at an operating pressure of not more than 1 MPa and has a pulse output in its kit that gives out one signal every 10 liters of water.

How to choose a water meter?

Russian legislation, step by step, obliges all owners of apartments and private houses to install individual ones for themselves. Among all models available both on the world and Russian markets, meters with an impeller and a mechanical water flow indicator have the best price-quality ratio. How to install , you can read in our article.

Currently, a wide range of water meters is presented in building supermarkets and online stores. They can be divided into three groups according to their origin.

1. Assembled at Russian enterprises, but from Western components and under a Western license.
2. Counters of Russian design, produced at domestic factories.
3. Imported counters, produced mainly in China.

If you look solely at the quality of the device, then the undoubted priority in the purchase should be water meters from the first group, designed and assembled on the basis of Western components. But, as usual, you have to pay more for quality, and usually such devices cost the consumer more.

Chinese devices are cheap, but they cannot boast of high measurement quality and reliability.

Domestic developments represent the golden mean. However, within this segment, reliability and accuracy indicators can vary quite significantly, either approaching the super-reliable "Germans", or dropping to a low Chinese level. In addition, when buying a domestic product, there is a very high risk of getting a Chinese product, simply repackaged in a box with Russian inscriptions.

When choosing a device, remember that universal counters hot and cold water cannot be equally accurate when measuring both parameters. It is best to purchase a specialized device, since hot liquid in plumbing systems has special characteristics that can quickly disable a conventional meter.

In order to choose a quality product, it is advisable to look at reviews from its direct consumers. Unfortunately, many reviews published on Internet portals are frank advertising. Therefore, when choosing a meter for your own home, it is best to use social engineering methods. Call the master from the local water utility or from the managing organization with at least five years of experience. For a couple of nice words and a small reward, he will take you on a tour of all the models of water meters used in your region, tell you about all their advantages and disadvantages. After all, it is not a fact that the most expensive counter will be the most reliable at the same time.

And if you motivate the master a little more, then he will tell you about how to deceive this or that water meter model and in what way, with a magnet or rewind. In addition, if the master has a sealer, then your friendship will save a lot of money when paying for utilities.

If you have already decided on a water meter model, then study a few useful tips to help you choose a reliable measuring device.

1. On the initial stage it is necessary to check the performance of the water meter. Locate the inlet pipe (usually there is a filter mesh on it). Just blow into this hole and see how the numbers on the counter begin to change. A good counter should work equally well in both vertical and horizontal positions.

   

2. When you blow into the inlet, or expose the meter's inlet to running tap water, the meter's glass cover must not fog up. If water vapor condenses on the inner cover of the device, this indicates a violation of the tightness of the meter.

   

3. In the near future, the requirements for the characteristics of apartment meters will only increase. In order to prevent illegal winding of meters, the devices are equipped with remote control means - outputting information about consumption to a remote device.

   

4. Water meters equipped with a pulse output can be of two modifications. The usual relay output of remote information retrieval does not allow a signal to be given when the line is broken, but meters equipped according to the European NAMUR standard react not only to wire breaks, but also to a possible short circuit. However, you should not rush to change the meter, the deadlines for mandatory remote reading can be pushed back more than once.

   

5. A good water meter should be equipped with spurs - nozzles on nozzles that allow you to fix it on water pipelines with the most popular cross-sectional sizes. Also, the meter can be equipped with a check valve. If it is not there, then the counter can be wound up by reducing its readings.

   

6. Check the information provided in the technical data sheet of the device. Usually the first one takes place at the factory. From the moment of the first verification to the purchase should not take more than a year, otherwise you will be forced to organize a re-verification procedure a year earlier.

   

As you can see, among domestic devices for determining the volume of water passing through a pipeline, it is quite possible to choose a decent model, which, at a rather modest price, will have good characteristics.
