Types of water meters

Thrifty users have long understood all the advantages of installing a water meter: during the reporting period, the figures in the payment bill correspond to the resources spent, and they no longer need to pay average tariffs, which are much higher than actually consumed. You have to pay for the service, but in fact the consumer overpays for something that he did not use. Another option that makes you think about installing a meter is a common house meter. In this case, the entire amount of resource consumed is divided equally and you don’t really want to pay astronomical bills for others.

Users note that installing a water flow meter helps significantly save the family budget. When thinking about the feasibility of installing a meter for cold and hot water, you need to analyze your expenses, habits, and take into account how many people live under one roof. If savings are obvious, it is important to study the market in detail and choose only the best water meters.

The solution to the problem of overpayment for unused resources is the installation of metering devices. A simple procedure will allow you to:

Save and pay only for the volume consumed.
Do not pay for water for periods of absence from the apartment (vacation, business trip).
Do not pay for water consumed by people illegally living in the house.
Save resources. Knowing that all the extra liters will cost a pretty penny, the user will not waste water.

The equipment for water metering is simple: the meter fits into the pipeline and shows the amount of water passing through it.

The most pressing question before the user before installing the device is “how to choose a water meter for an apartment and which one is better.”

Water meters

In addition to the fact that metering devices are designed only for hot or only for cold water, as well as for cold and hot water at the same time, there is another gradation of flow meters. When deciding which option to choose, study the strengths and weaknesses of each sample. The device can be:

Volatile - can be connected to the mains or run on battery power.
Non-volatile - able to work without additional power.

According to the type of device, flow meters are:

Mechanical (tachometer). The most common category of devices. Adapted to work with purified water, characterized by a simple device. Disadvantages include the possibility of measurement error. They are divided into single and multi-jet. The latter are more accurate.
Energy magnetic water meters. Mainly used as communal buildings. The operating principle is based on magnetic induction. They often have a pulse output for transmitting readings remotely.

Gardena Water Smart

In addition to the common options, there are also lesser known ones:

Ultrasonic – used when liquids have aggressive contents.
Volumetric – even the minimum flow is taken into account.
Vortex - influence the flow of the technological process.

When choosing a device, consider what kind of device you need: a water meter for cold water, hot water or a universal one.

To choose the best device for metering resource consumption, you need to answer the following questions:

What degree of accuracy is needed.
Does the manufacturer provide warranty service?
Are the meter dimensions suitable for installation in a particular location?

You need to read reviews of the flow meter you like on the Internet on forums. Here you can get the information that is provided only by users who have already tried the device in action and formed their own idea of the water meter.

Whatever type of flow meter you choose, there is a way to check the sealing of the metering mechanism, which is very important.

Blow into the counter pipe and note whether the surface covering the counter mechanism has fogged up. If drops of moisture appear on the glass, the device is depressurized and there is no need to purchase it.

Experts recommend keeping up with the times and even being a little ahead of it. For example, when choosing a flow meter, give preference to a counter with a pulse input. Even if you don’t currently have an automated accounting system, modernization can come at any time.

Comparative characteristics of tariffs without a meter and with a meter

It would be a good idea for apartment owners to find out the established standards in their region, regardless of the presence of water meters. In Russia, the average fee for cold water (per cubic meter) is 30 rubles, for hot water 100 rubles.

Attention! It is easier to calculate the total amount to pay for the service using a meter. To do this, you need to multiply the indicators on the meter panel by the current tariff for DHW and cold water.

If there is no device in the apartment, then to calculate it you will have to perform the following steps:

1. count the people registered in the apartment.

2. find out the current water tariff in the region.

3.calculate the final number.

4.add the value of the increasing coefficient, which is specified in the Decree of the Government of the Russian Federation No. 344 of the 13th year. This coefficient is valid in premises with uninstalled meters, or it is faulty. The coefficient is 1.5.

Example: A family of 3 people lives in St. Petersburg. The consumption rate per person for cold water is 4.9 cubic meters, for hot water 3.49 cubic meters. For a cubic meter of cold water you have to pay 30.8 rubles, hot water – 106.5 rubles.

Let's calculate the amount to pay for water for this family:

1.with 3 people for cold water 3 x 4.9Х3.08Х1.5= 679.1 rub.

2. per person for DHW 3 x 3.49 x 106.5. x 1.5 = 1672.6 rub.

3. total amount 2351.7 rub. from family.

In fact, the average person consumes 2.92 cubic meters of cold water per month and 2.04 cubic meters of hot water. Thus, if you install a water meter in an apartment, the same family from St. Petersburg will pay much less for services:

1.with 3 people for cold water supply according to the counter 2.92 x 30.8 x 3 = 269.8 rub.

2. with 3 people for hot water according to the meter 2.04 x 106.5 x 3 = 651.8 rub.

3.total amount 269.8+ 651.8 = 921.6 rub.

If you install a meter, you will have to spend up to three times less than the family budget on paying for water. Therefore, installing meters to measure water flow is beneficial and necessary.

Attention! Using a meter, your water bill will be three times less than without a meter.

Stop

Sellers of magnets (neodymium) are actively offering to save money by installing a neodymium magnet for a water meter: flow meters stop or slow down, the resource can be used uncontrollably, and you don’t need to pay anything. Implementers suggest simply choosing a magnet to stop the water meter and forget about material costs. In fact, the situation looks somewhat different.

It may be possible to stop the water meter with a magnet on some models, but any inspector can easily find out about this fact during an inspection. There are many ways to detect unauthorized intervention, and the average person does not know all the diagnostic methods used by housing and communal services workers. As a result, the user will have to pay a fine and pay for a considerable period of time for the resource consumed, not according to the meter, but at a much higher price. But if this does not stop you from illegal actions, you should think about one more thing.

ZENNER ETWI-N DN

As a result of the influence of a magnetic field on the device, it suffers serious damage. It is not surprising that the flow meter quickly fails and shows inaccurate data. Stopping a flow device with a magnet is an action that will sooner or later entail a lot of unpleasant consequences.

Mechanical type meters with a mechanical display that records the flow rate in m³.
Mechanical type meters that have a sensor through which a signal is transmitted.
Electronic meters, with the ability to take readings remotely.
Digital smart meters with a mechanical or electronic display (they are called capsule and modular meters).

In addition, according to their operational characteristics, meters are also divided into several classifications. For example, a pulse meter, which is practically no different from a regular meter, but has a circular dial indicator that is located on the display and provides information about liquid consumption.

A given amount of liquid that passes through the meter corresponds to one full circle of the arrow. By counting the number of complete turns of the arrow and then multiplying them by the volume of liquid passing through the meter, it becomes possible to calculate the amount of liquid consumed over a certain period of time.

Installation

To avoid getting into an unpleasant situation, you should entrust the installation of water meters to specialists authorized for this type of activity. The rules for installing flow meters are simple: the device must be installed in such a way that representatives of the water utility seal the device and allow it to be used. Only a specialist should install a water meter, otherwise the meter will fail prematurely, work incorrectly, and the like.

It is preferable to install a special filter in addition to the meter itself. This will help protect device parts from premature wear and failure.

Vodokanal employees insist that water meters need to be installed in a convenient location with good access. This requirement is also convenient for the user: it is important to take readings without problems and, if necessary, repair or replace the device.

NORM SVKM-25X

Devices, if installed by a good specialist, will safely work for the time stated by the manufacturer.

To ensure that the installation of the device goes without problems, pay attention to the correct choice of flow meter.

Study the quality of water supplied to your home. If it contains a large number of foreign particles and impurities, you should choose a meter without moving mechanical elements.
Pay attention to the housing material that comes into contact with water. Brass and bronze elements have proven themselves best. They withstand contact well with harmful particles often present in water. Silicon and aluminum did not perform very well: the components made from this material are fragile and poorly withstand loads.
Check that the package is complete. In addition to the necessary elements, a quality certificate must be attached.

The longer the verification interval, the better the water meter is considered. Typically this is six years for a cold water meter and four years for a hot water meter. Users recommend giving preference to universal type meters, as they can measure cold and hot water and be mounted on any surface of the pipeline.

Verification

Water meters are verified after a certain period of time specified in the technical data sheet.

The user is faced with a choice of where is the best place to check water meters in Moscow, for example. It is necessary to select an organization authorized to carry out the verification procedure. Upon completion, the owner receives a document indicating the result of the verification: permission is given to continue using the device or a recommendation to replace the meter with a new one. The organization must have permits to carry out verification. The owner chooses a verification company to verify water meters, taking into account all the requirements. The procedure is mandatory, since over time the accuracy of the readings undergoes changes and the results become less accurate. The user may overpay for the resource consumed, sometimes the error is in the direction of the consumer, which the water utility is not interested in. For this reason, verification is in the interests of the owner and the water utility.

The procedure is quite tedious and requires a certain amount of time to contact the supplier’s organization. It is necessary to write a statement requesting verification of the device. After some time, an inspector will come and record the readings of the device. It is necessary to remove the water meter and submit it for verification. At this time, water is accounted for at average rates. The verification result can be very different; often the device is considered unusable and needs to be replaced with a new one.

Therefore, many water consumers ask the question: “Testing or replacing water meters - which is better?” The person decides for himself what is easier for him. Some never do the verification, immediately replacing the meter with a new one.

Choosing a water meter is an important step. A wise choice will allow you to use the resource without problems and get accurate results for many years.
