How to choose a water meter?

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

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

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 meters, mainly produced in China.

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

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

Domestic developments represent the golden mean. However, within this segment, the indicators of reliability and accuracy can differ quite significantly, either approaching the super-reliable "Germans", then dropping to a low Chinese level. In addition, when buying a domestically produced 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 meters for 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 regular meter.

To choose quality product, it is advisable to look at reviews from its direct consumers. Unfortunately, many reviews published on Internet portals are outright advertising. Therefore, when choosing a meter for your own home, it is best to use social engineering methods. Call a foreman from a local water utility or from a management organization with at least five years of work experience. For a few pleasant words and a small reward, he will guide you through 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 meter will be the most reliable at the same time.

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

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

1. At the initial stage, it is necessary to check the performance of the water meter. Locate the inlet (usually contains a filter mesh). Just blow through this hole and watch the numbers on the counter begin to change. A good meter should work equally well in both vertical and horizontal layouts.

   

2. When you blow into the inlet, or substitute the inlet of the meter under the flowing water from the tap, the glass cover of the meter should not fog up. If water vapor condenses on the inner cover of the device, this indicates a violation of the meter tightness.

   

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 means of remote control - the output of information about consumption to a remote device.

   

4. Water meters equipped with a pulse output can be of two modifications. A conventional relay output for remote information readout does not allow giving a signal in case of a line break, but meters equipped according to the European NAMUR standard react not only to wire breaks, but also to a possible short circuit. However, there is no need to rush to change the meter, the mandatory time frame with remote reading may be postponed more than once.

   

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

   

6. Check the information specified in the technical data sheet of the device. Usually the first one takes place in the factory. It should not take more than a year from the moment of the first verification to the purchase, otherwise you will be forced to organize the 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.

Hot water meter "Norma SVK-15 G"

The increase in tariffs for utilities... Almost every season, the cost of using water increases in all conditions. If you pay according to actual numbers, then you will quickly notice the difference and some damage to your own wallet, but the installed water meters will not only allow you to control fluid consumption, but also help you save some money. To rationally use water from a centralized water supply system, it is recommended to install svk 15g devices.

Such designs can be universal and of an individual type. The options for hot and cold liquids are perfect for their tasks, so they are increasingly being used at home. Today water meters "Norma" IS are included in the state rating of the best devices.

Before going on sale, each calculating device is assigned certain qualities and working properties. It is customary to include the following qualities in a number of technical parameters of IS "Norma" water meters:

Attention! When trying to rewind the readings of the water meter, it makes no sense to use the magnetic method in this matter, since the counting unit is equipped with a special anti-magnetic system.

Advantages and disadvantages of IS "Norma" water meters

Devices for cold water, as well as for hot water, are characterized by the release of liquid without reducing the pressure. At the same time, they consider the readings without errors if they have passed a timely check.

The most important advantage when installing a set of water meters IS "Norma", as the reviews show, is payments strictly according to tariffs and only for the amount of cubic meters used. Herrid kits have similar advantages, which are placed in the rating. Now you don't have to pay for every person living in the house.

There is an opportunity to control the consumed water and save it, if necessary. There is a strictly fixed tariff here. Water meters IS "Norma" have an aesthetic appearance, which takes into account the requirements of SNiP. Due to the design resistant to aggressive environments, the devices can withstand temperatures up to +130 degrees for a short time.

Most of the units of this manufacturer are equipped with a pulse output. This system allows you to control the flow of hot water without taking it into the cold cell. Some models of Gerrid and Valtek have similar properties. Reviews of these installations are mostly positive.

Of the shortcomings, the presence of counterfeit type control devices is noted. It should also be emphasized that it will be quite laborious to install Norma devices with a lack of skills. Consequently, this procedure requires a call of specialists and some installation expense.

Maintenance of water meters "Norma"

In the procedure for servicing water meters IS Norma cold and hot, it is customary to include some renovation work, as well as mandatory operations that are performed on a regular basis. These requirements can be evidenced by reviews on any forum. We draw the attention of the consumer that liquid metering and control devices equipped with a pulse output will be serviced at an order of magnitude more expensive. So, let's see what is included in this procedure.

Each individual unit, regardless of brand should be serviced similarly. An exception for accommodations is the individual term. As the user reviews show, gerrida's equipment is capable of working without mandatory checks for up to 7 years.

Counter analogs "Norma"

Any water instrument and device has an assortment of analogues. So, today the gerrida unit will serve as excellent substitutes, as numerous reviews claim within our country. It has proven itself excellently in recent years, and is used for both hot and cold water supply.

Attention! Pulse unitgerrida can be used not only for home conditions, but also as a device where there is a requirement to correlate moisture with other substances, where liquid may be supplied irregularly.
