Water meters - selection and installation

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?

Water meter SKB 40

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.

For hot water

They must withstand high temperatures well, the body must be made of metal only.

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.

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.

Water meters VSKH 15

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

  1. 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.
  2. 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.
  3. 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.

Advantages and disadvantages of water meters

After you install a water meter in your apartment, you will almost immediately see its advantages:

  1. The most important of them is that from now on you will not have to pay for extra cubic meters of water. If previously you had to pay at the average tariff, which was calculated taking into account the people registered in the apartment, even if you practically did not use water, then with a meter you pay for the same amount as much as you use.
  2. Another advantage of having a water meter is the ability to monitor your water consumption and control it if necessary. That is, if you suddenly start consuming more water from the tap than the family budget can handle, then thanks to the meter you can notice this and try to use this resource more rationally and economically. Accordingly, this will have a positive effect on your wallet.
  3. As mentioned above, when paying for water supply at a standard tariff, each person registered in the apartment is taken into account in the calculation. If one of the family members lives at a different address or is temporarily absent, you will still have to pay for them. And when the volume of water is recorded, then naturally the tenant does not have to pay for it.

In addition to all the advantages, there are also some disadvantages of installing a water meter:

  1. If you purchase a device of poor quality, it may count cubic meters with an error, which will affect the amount of payment.
  2. If the meter breaks down or the seal is damaged, then charges for the repair period or until a new seal will be made at the general rate.

Installing a meter is not a labor-intensive task, and it certainly pays off. Although you will incur certain costs for its purchase, installation, sealing and inspection every couple of years, you will save a lot during your use of it.

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.
