What is the water meter?How to choose a water meter?And how can you save on utility consumption of resources?Answers to these and many other questions you can find in this article.
What is the water meter?
meters, or the water meter, has recently become more and more popular thanks to the reform of public utilities.With it carried out taking into account actual waste water, both hot and cold.For a month it will help save about 100-500 rubles.When installing the metering savings palpable.It should also be remembered that the tariff is necessary to pay only for those who are registered in the apartment.
Currently, the Russian market domestic manufacturers an excellent job with the production of measuring devices, and the percentage of imports is small.Many manufacturers still use imported components for the manufacture of meters, in most cases they are imported from European countries: Germany, Italy, France, etc.
Classification
So, before choosing water meter, you must stay at the varieties of these devices.In today's market there are a large number of water meters.They are classified according to the principle of action:
- mechanical (vane and turbine).
- Vortex.
- Electromagnetic.
- Ultrasound.
In addition, these devices can be volatile and nonvolatile.In the first case, the device operates from the mains, as well as in the floor construction provides a battery that is safety (optional) power supply.
If you do not know which to choose water meter, it is important to know that the mechanical meters are also divided into two types - for hot or cold water.Their fundamental difference from each other - this is the material from which the elements of the counter (bearings, impeller).Counters of cold water may be used up to + 40 ° C, hot - not more than + 130-150 ° C.Counter intended for hot water, and may be used cold.
Also, water meters are divided into industrial (for water metering in apartment buildings, large industrial premises, nominal diameter 25-400 mm) and domestic (private houses, apartments, nominal diameter of the meter - 15-25 mm).
How to choose a water meter with a tachometer?
Tachometer is a mechanism in which the flow of water by means of mechanical pressure results in the activity of the blade or vane wheel of the turbine, thus carrying out their rotation.Then, the rotation is transmitted calculating elements which detects the amount of consumed liquid.
tach water meters are divided among themselves, depending on the design features.Distinguish turbine, single-jet and multi-jet.There are also combination of meters, which simultaneously combines the turbine and impeller flow meters, arranged in parallel.When a head of a small amount of water accounted for the wing unit, with increasing pressure through a special pipeline with valve overlap wing water meter and water is taken into account by means of a turbine meter.
Counters: how to choose?Reviews consumers
When choosing a metering device is a fundamental factor in its value.Low cost can guarantee high quality, but the purchase is too expensive counter is not always justified.
companies and experts praise the electronic equipment, in other words, intelligent devices of foreign manufacture.They have many advantages, but also have only one drawback - it is the price.These water meters, even with a small water pressure, show reliable evidence, and they do an excellent job with a lot of pressure in the water system.It is a versatile instrument used for cold and hot water flows, and their installation is not dependent on horizontal or vertical piping arrangement.And most importantly - to take on the electronic water meter metrological verification will not be particularly difficult, for it removed the upper part, and all connecting parts remain in place.It is this feature of these devices is often noted in a review of consumers.
cost
So today, preferably intelligent water meters.How to choose?Price - how significantly it will hit the pockets?Brands such metering devices are such companies as «Zenner» and «Siemens», the cost ranges from 1,000 to 4,000 rubles.
in Russia often collect mechanical devices, using foreign components.Their price ranges from 300 to 800 rubles.You will notice that the cost of such meters is much less than that, they are presented in stores in large quantities.
Features selection
before selecting water meter for the apartment and get it, you need to pay special attention to the period between the date of verification specified in the passport, it shows its longevity.Metering devices can lie on the counter for a long time, and the date still remain the same.It was found that during calibration for the mechanical counter is 5 years for electronic - 10 years.
Also, before choosing water meter, it is important to take into account indicators such as the capacity of the device, in other words, its productivity, which is measured in m3 / h.
setting the counter into the living room, it is necessary necessarily agree with this action by the management company.There will suit not every equipment, read the recommended counters.Since checking the selected device alone can not take, and testimony from him at payment of utility bills will not be considered.
Operation and Maintenance
Once you've chosen your model, you need to call professionals who will make the installation of the device.Next, you need to register and seal, for this you need to call the representatives of the urban water utility.
The average service life of water meters is 12 years.Thus already after 4-6 years to go through the meter calibration.This procedure is very important because during the years of continuous operation significantly reduced the accuracy of readings.
due to incorrect reading quite a lot.Among the most common is the hard water and slags pipelines.When the slag accumulates in the piping, the pressure in them becomes higher, the opening device becomes difficult to pass, and its turntable starts to rotate faster.Indications are a result of the significantly higher than the actual water consumption.To prevent this problem, it will be enough to buy a strainer.
Terms mounting
Now you know how to choose the right water meter.But to his testimony untrue and he could function smoothly for many years, during installation you must adhere to the following rules:
- engaged in installation of the metering device can only complete the field of welding and other works on the preparation of the installation nest.
- direction of the arrow, which is located on the sidewall of the water meter, must coincide with the direction of fluid flow.
- water meter counting device mounted up.
