In order to pay only for the water you use, it is necessary to install a meter for measuring the amount of water in the apartment or, as they say, water meters. What kind of water meters are and which of them are suitable for household use and will be dealt with.
Water meters set to not pay "for a neighbor"
Types and types of water meters
There are several types of water meters, but they can all be divided into two main groups: non-volatile (using mechanical processes) and volatile (need electricity).
In general, there are four types of counters:
From all that has been said above, it turns out that in our actual conditions - old pipes and not the cleanest water - only tachometric meters are suitable. They are basically installed.
Types of tachometric counters
Mechanical counters are good in that no additional conditions are required for their operation. There is a stream of water - they work, there is no it - they cost. That's just a long simple they do not really like - because of the presence of salts in the water impeller or turbine can stop spinning. This means that you will need to change the meter.
Classification by water temperature
Devices of the account of the charge of water (this is the official name) is for cold and hot water. They differ in the range of operating temperatures:
- for cold maximum is + 30 ° C;
- for hot + 130 ° C;
- universal - operating temperature range - up to + 90 ° C.
Even if the water meters of the same type and the manufacturer they have one, the difference in price is palpable. But it is justified - heat-resistant materials are used for hot water supply, and they are much more expensive. To outwardly they could be easily distinguished, the bodies are painted in different colors - the counters for cold water are usually blue, for hot - red, universal have an orange color.
According to the principle of action
Under the general principle of operation, this type of water meter has several varieties. First, there are two principles of action:
But not everything is so simple: multi-jet tachometric water meters are only for large pipe diameters (more than 40 mm in diameter). For apartments, they do not fit.
By the method of installing a counting and rotating mechanism
More important for us is the division of the method of installing a counting mechanism. On this basis the water counters are divided into dry and wet. In the wet, the counting mechanism is in the water, because it quickly fails. In dry-type devices, the counting mechanism is separated from the water by the plate and they work longer.
There is another kind of tachometric meters - a valve. In such a water meter, a shut-off valve is additionally installed, which makes it possible to block water. For what it may be necessary, it is difficult to say, because in the installation before the water meter it is necessary to put a shut-off valve. It is needed in case it is necessary to change or check the counter, here by this tap, if necessary, and turn off the water.
Inside the tachometric meters there is a turbine or an impeller, respectively, they are divided into turbine and vane. All the difference in the location of the axis of rotation. In the winged it is perpendicular to the flow, to the turbine ones - in parallel, although the shape of the rotating wheel is identical. Winged water meters are more sensitive and can measure weak water flows, but they have a disadvantage - they almost completely block the water passage, which reduces the capacity of the water pipe. The second minus - in case of a malfunction (if the impeller ceases to rotate), the flow is almost completely blocked.
| Name | For what kind of water | A type | Feedthrough Diameter | Mounting length | Min / Max Consumption | Connecting dimensions | Price |
|---|---|---|---|---|---|---|---|
| SVK-15-3-2 Arzamas | universal | airworm | 15mm | 110 mm | 0,06 - 3 m3 / h | g3 / 4 thread | 600 rub |
| VSHN DN 25 | cold water | winged single-jet | 25 mm | 260 mm | 0,07-7 m3 / h | thread 1 "1/4" | 72$ |
VSGN-25 DN | hot water | winged single-jet | 25 mm | 260 mm | 0,14-7,3 m3 / hour | thread 1 "1/4" | 87$ |
| VALTEC VLF-R-L | universal | airworm | 15 mm | 110 mm | 0,01-3 m3 / h | thread 1/2 " | 800 rub |
| ITELMA IS.160005 (vertical installation allowed) | hot water | airworm | 15 mm | 110 mm without fittings | up to 3 m3 / h | G3 / 4 "" | 890 rub |
| PULSE 15-X (vertical installation allowed) | cold | Winged, dry | 15 mm | 80 mm without drifts | up to 3 m3 / h | thread 1/2 " | 730 rub |
To combine the advantages of both types of rotating elements, a combined tachometric water meter was invented. It has both a turbine and an impeller. With a small water flow, it is fed to the impeller, while a large flow to the turbine. But the cost of this type of equipment is already quite high.
One more thing: turbine water meters are produced in diameters from 40 mm, so for owners of apartments there is no choice. We have to put the winged water meters - others just do not fit.
Additional Features
For the automation of the reading process, there are special patches (based on reed switches or with radio transmission). They are not compatible with all instruments, so water meters are usually sold immediately with such additions.
There are winged water meters with the possibility of temperature control, they can still be called multi-tariff, because they calculate the amount of water consumed at different temperatures. They are relevant for those countries in which the mechanism for the allocation has been developed. Russia, also refers to them (Resolution of the Government of the Russian Federation No. 354 of August 27, 2012).
The multi-tariff hot water meters have a small processor and memory capacity, they are most often operated by a rechargeable battery. Since the power requires only a few sensors, a microprocessor and memory, the flow rate is very small. One feeder is enough for 5-8 years.
The temperature data is stored in the microprocessor's memory, where they can be extracted. The memory is periodically cleaned, so it is necessary to carry out a check periodically.
Manufacturers of water meters are very many. The article describes which meters are recommended to install in apartments and houses, the order of installation and registration of the device, as well as tips on how to correctly take meter readings.
Water - a natural resource, which is constantly becoming more expensive. State rates of water consumption per person significantly exceed its actual consumption. To save water and pay less for it, you need to install in the apartment or house water meters.
Water meters are a device whose function is to measure the amount (volume) of water consumed in apartments and enterprises, where the water pressure level is 1 MPa. The measurements are made in cubic meters.
Practice shows that the consumption of water by a family of three people that uses water meters is 2.5 to 3 times lower than the normative consumption. However, after a certain time, the counters will have to be dismantled and given for testing, and this is associated with additional costs. Nevertheless, the benefits of using meters for the user of water are obvious: they quickly pay for themselves and help to really save the family budget.
What are the counters?
Usually, efficient owners immediately set up a counter in the apartment: cold and hot water. The problem is removed in a complex, and the accounts in the payment for the next month will noticeably brighten the eye.
What is the difference between instruments that take into account cold and hot water?
Externally: the red counter is used to account for hot water, blue is for cold water.
The details of the cold water meter can withstand a low temperature (up to 40 degrees), and for a hot one - up to 150 degrees.
There are also combined instruments that are capable of taking into account the flow of water (cold and hot).
Types of cold and hot water meters
Classify the water meters according to the principle of their operation:
Mechanical (tachometric). The flow of water in such a counter rotates the turbine or impeller of a special shape. Rotation of the turbine or impeller transmits to the device information about the amount of water passed.
Electromagnetic. Water passes through the device and forms a magnetic field. The device records the rate of formation of the magnetic field and on this basis indicates the amount of water consumed.
Ultrasound. The flow of water as it passes through the device creates sound vibrations, depending on the speed of the water flow and its volume. Accounting for water occurs when the device evaluates all the characteristics of sound.
Vortex. The design of the device has a body placed inside the water stream, which creates vortices. Their frequency is recorded by the device in the form of the expended water.
Electronic. The principle of operation is based on reading a small-sized chip of water flow data and transferring it to the control room via the network.
Usually, apartments install mechanical or electronic water meters.
A wide range of mechanical water meters is on the market. Mostly they are produced by domestic companies. The meters are designed for local operating conditions, taking into account the characteristics of water properties and water supply systems.
Increasingly, domestic producers use imported materials in their goods, which makes them more quality and durable.

Disadvantages of electronic counters
Compared to mechanical devices, electronic meters are more expensive.
The need to provide power to the electronic unit of the device.
When buying an electronic meter you will need to focus on the price, which is 4 times higher than the cost of a domestic mechanical analog.
Manufacturers of water meters
In Russia there are many manufacturers of water meters. Popular are the brands "Teplovodomer", "Multisystem", "Meter", "Vodopribor", "Beregun". It is worth paying attention to the devices SGV-15 and SVK-15, produced by the plants Staroruspribor and Gazelectronica, which are designed to account for water (cold and hot).
Very popular in Russia are imported equipment, equipped with electronic control, such companies as Siemens, Zenner, Minomess.
When choosing a cold or hot water meter, pay attention to the following characteristics:
The nominal pressure at which the device records the reading.
Temperature range of the meter.
Limit of sensitivity of the device.
Limit value of adder.
Permissible loss of head in the unit.
Scope of Accounting.
Video review: Choosing a counter for water
Buy a counter preferably in a branded store, where you will purchase a device that meets the standards. Buying goods on the market, you should take a closer look at the deal, as there is no guarantee of obtaining a quality device. Wherever a device for water consumption is purchased, you need to make sure that:
The device has a corresponding license;
Warranty service is provided;
It is possible to regularly check and if necessary replace the device.
Rules for installing the meter
The reliability and quality of the device depends on its correct installation.
The meter must be installed in such a way that its housing is easily accessible during maintenance work, and the dial and panel are clearly visible for taking readings.
Set the counter after the end of all installation works, connected with the system of cold or hot water supply.
The counting device should be located on the dial face up.
The arrow on the housing of the device should be located in accordance with the direction of the flow of water in the system.

Registering counters
After the installation of the meter, representatives of the supplying organization shall prepare an acceptance report. The meter is sealed and thus put into operation.
It must be remembered that water metering devices should be regularly checked at certain time in the controlling bodies.
When the verification time comes, the meter needs to be dismantled and provided for the respective operations. The procedures for dismantling and subsequent installation after verification are accompanied by the preparation of acts and seals the instrument.
How to take readings of water meters?
The meter reading is performed monthly in order to determine the amount payable for the service. If you are recording data for the first time, you first need to determine where the cold meter is located, and where the hot water meter is.
We remind: the cold water consumption takes into account the device of blue color, and hot - of red. To determine this or that device it is possible and in another way: it is necessary to open a tap, for example, of cold water, and to see which of the counters "will start moving".
How to take the meter correctly?
On the scoreboard of the counter there are eight cells for numbers. In the first five cells appear black numbers, and in the last three - the numbers are red. The meter readings are taken in cubes, so when taking into account the consumed water, the last three digits are not taken into account, since they fix only liters.
The first five figures should be taken into account - they show the cubes. On the new, just installed counter, there will be some minimum indicators, they appeared when setting up the instrument in the factory and during the inspection during installation. The zero point of reference for your device will be the figure that the representative of the service provider indicates in the certificate and the subscription book.
Write the initial readings in notepad. For example, it will be 00000058. A month later, write down the new readings of the device, suppose that there will be numbers 00010558. The data says that 10 cubic meters and 558 liters of water are consumed per month.
The amount can be rounded to 11 cubes and pay for them to the supplier. Over time, the meter reading will not be difficult. You can even analyze the nature of your family's water consumption and find real ways to save this critical resource.

Thus, the installation of meters in an apartment, house or enterprise results in significant water savings and, accordingly, saving money. When selecting meters, be sure to target the reputable manufacturers of products.
Toilet bowls - what varieties, and what to look for when choosing?
Installation of devices for accounting for water consumption in an apartment or a house is a matter of saving both water itself and optimizing the family's expenses for paying utility bills. But before choosing water meters, it is necessary to find out how they can be installed on an existing or only installed water supply system.
It will be necessary to take into account the correspondence between pipe diameters and meters, their compatibility by type, and also their throughput. It may be useful to visit a management company to find out what requirements for these meters can be presented, and also which types they recommend, so that later there are no questions and difficulties with their installation, maintenance, verification, etc.
Counters for water - what they are
All water meters, irrespective of their design features and operation principle, can be divided into water consumption meters:
- cold, calculated to a temperature of 40 ° C;
- hot, work up to 90 ° C, and some appliances and up to 150 ° C.
Also, before proceeding to the selection, it is necessary to learn that the counters are:
- non-volatile;
- volatile,
the second, when the supply of electricity ceases, they simply stop working.
And of course, it is necessary to determine the principle of the water meter. For this, the following types of water meters are on the market:
- tachometric;
- electromagnetic;
- ultrasonic;
- vortical.
As a household appliance, the most common are tachometric with a mechanical principle of operation, less often - electromagnetic ones. Vortex and ultrasonic, basically, are intended for the account of water on industrial objects.
Tachometric counters
This type of counters are the most common in urban apartments and many country houses. Their main advantages: small size, quite simple and convenient installation, low cost of the device itself. It can serve up to 10-15 years, but because of the low price, comparable to the cost of verification, many apartment owners prefer to replace them during planned verification activities with new products.
Sometimes this kind of counters is called vane instruments because of their design feature, which is based on an impeller or a turbine. But this species also has its subspecies: they can be single-jet or multi-jet, depending on the method used to calculate the amount of water passing through. Therefore, which water meter to choose - the question is rather difficult and responsible, since an error in the exact selection of the correct device instead of saving may result in additional costs. In addition, it should be noted that the vane apparatus can be installed on pipes up to 40 mm in diameter, and turbine ones from 50 to 200 mm. And for pipes with a variable head, combined devices consisting of both the impeller and the turbine are recommended.
Device Diagram
Single-jet meters
In this device, the amount of water is counted by the rotation of an impeller or turbine rotating the total flow of water in the pipe, and then, through a magnetic coupling, the transfer to the housing indicator is carried out. The mechanism itself, designed to count the water directly from it, is isolated, the so-called "dry method", which allows us to obtain sufficiently accurate data. Often, these devices are provided with special protection against magnetic influence, and in addition, they can be mounted with the ability to output data from the pulse module to the remote device, which facilitates (as evidenced by positive feedback from consumers) the procedure for taking readings to record and pay for services.
Multi-jet water meters
Multi-jet instruments have several differences from their single-jet "brothers", the main one being that thanks to the possibility of dividing the total water flow in the pipe, directly in front of the impeller into several separate ones, it is possible to obtain more accurate data, practically without errors. It should be noted and such an important point as the possibility to perform the calibration of the device without removing it: it is enough to remove only the upper part of the device. They can also be fitted with modules for pulse output, and the installation / dismantling itself is easy and can be carried out even independently, provided that such a device is then sealed (some companies do not encourage this method of installation and require that the installation be carried out by their specialist, which will seal the counter).
Installed counters
"Wet" and "dry" devices for water metering
The location of the water accounting mechanism determines what kind of tachometric meters are available - "dry" or "wet". As follows from the logic, in the "wet" counters it is in the water and, as a consequence, suffering from the presence in it of various suspended particles and contaminants, quite quickly goes out of order. This problem can partly be solved by using a filter, which should be installed directly in front of the counter. In "dry" devices there are no such problems, since the accounting device is protected by a non-magnetic partition and therefore such a device is more durable and, most importantly, retains the ability to show an accurate result longer.
Tachometric counters are also called mechanical, respectively, refer to non-volatile water meters, which in some cases is the decisive moment of choice, and such a problem as sensitivity to the magnetic field is successfully solved using antimagnetic protection.
Electromagnetic flow meters
As a household appliance, this meter, although it is used, is much less common, mainly in private houses equipped with an emergency source of electricity, since these are volatile devices. Preference is given to them because of the possibility of obtaining high-precision readings, calculated as the ratio of the area of the flow to its velocity. But the indications can be corrected in any direction by the features of the chemical composition or the physical properties of the water, although in this case the error is small. It should be noted that specifications This type of device is not designed to work in absolutely pure water, but one can not ignore the fact that the presence of a large number of suspended particles can in a very short time to disable it.
Simple Counters
Ultrasonic and vortex water meters
These types of devices are designed to account for a large number of water consumption and are used in industrial facilities or in large suburban households, in such facilities as hotels, sanatoria, etc. Because of their rather high cost, as well as energy dependence, it is unprofitable to install them in urban apartments.
Vortex counters in calculating the amount of flowing water use the flow velocity and the frequency of the vortices formed on the special element placed in it. And the main principle used for counting in ultrasonic devices is the analysis of data obtained from sensors that propagate ultrasonic waves in opposite directions, while calculating the difference in the passage of the same segments "on" and "against" the flow of water.

Important about devices for the account of the charge of water
After it is decided what water meters are best to install, when buying them, you should pay attention to ensure that they meet the requirements of GOST, specify what their warranty period and installation size. Also, it is necessary to find out whether there is a possibility of receiving service and what time interval should be between calibration of the device. It is important to know that water meters must have a technical passport in which the number of the device is indicated and, of course, it must coincide with that indicated on the device. The technical passport contains information about the terms of warranty service, the term of which is often 1 year, but manufacturers who are confident in high quality and reliability of their devices, as well as caring about their customers, can give a guarantee for a period of 3 to 5 years.
Which water meters are better than video:
Water meters are used to measure the volume of water passing through the pipeline per unit of time. The unit of measurement is cubic meters (m 3). The device is installed in apartments, houses and industries. With its help, costs are significantly reduced - the user pays only for the volume that was consumed. Often the meter is used as a control element (when information is needed on the volumes of liquid consumed).
Types of flow meters
First of all, the counters are divided into devices to account for the flow of cold and hot water. Their main difference is the material from which the parts of the device are made. Analogs designed for the calculation of cold water, work properly at temperatures up to 40 ° C, for hot - up to 90 ° C. The latter are allowed a large error. There are universal meters, they are used to measure the flow of both cold and hot water.
The devices are manufactured for pipes of various diameters. A number of the list starts with a diameter of 15 mm and ends at 100 mm. Small are intended mainly for use in apartments, and large ones are used in production.
By the method of measurement, the meters are divided into tachometric and electronic. The first group works with the help of an impeller (turbines), while the latter is used more often for water accounting at the scale of industrial complexes and is carried out on logical elements or sensors. In this case, any mobile parts are structurally excluded.
Tachometric instruments are very in demand. The principle of their work is reduced to calculation of fluid volume, passing through an impeller or a special turbine, in the design of which a magnet is provided. So, the number of revolutions is registered with the help of a special counting mechanism. The latter is protected from penetration of moisture into it. It is also important to exclude magnetic influences. Counters are mounted in both horizontal and vertical position. They do not need to supply power sources, which is an important plus. And here are some electronic analogues without power do not work. By the way, they, in turn, are also divided into several subspecies. Among the electronic meters are:
- electromagnetic,
- ultrasonic,
- vortical.
Electromagnetic devices the flow rate of the liquid passing through the electromagnetic coil is measured. Such devices are very expensive, so to account for water in the apartments they are practically not used. But the devices are in demand in production, as they are considered the best alternative to tachometric analogues.
Vortex counters They are used to control the account of water during the implementation of technological processes. The principle of their work is based on the intensity of the pressure drop. Structurally, the device provides a streamlined body (often a trapezoid). Behind it, as the liquid passes through the pipeline, vortices are created that act on the pressure sensors. The intensity of the change in pressure and reflects the rate of flow of water.
Ultrasonic counters Also installed on industrial equipment. In order for the meter to work properly, it is necessary to mount it on a straight, rather long section of the pipeline. This requires that the pipeline is not drained. The cost of an ultrasonic water meter is less than the cost of an electromagnetic meter, but this did not make the devices popular. The principle of their operation is based on the generation of radiation, which is perceived by the receiver. Radiation passes through the flow of liquid, and the more time it takes for the beam to be perceived by the receiver, the higher the fluid velocity.
Today unique devices are produced with reed switch. With their help taken readings processed by a computer. So, the information on accounting for the flow of water comes directly to the ERC department. Such systems are still unpopular, but the future is bound to follow them.
The translation of all objects without exception into electronic analogs will not be difficult. Manufacturers have provided such an opportunity and implemented a special electronic accounting module in the cases of modern water-measuring mechanical devices.
Service life, installation and manufacturers
Each meter is designed for a certain lifetime. On average, this parameter is equal to 4-6 years of operation. It depends in many respects on the accounting of what water the device is designed for: if it is hot, then the time is shorter; if the cold - more time. In many respects the life of the device depends on the manufacturer. Universal instruments (designed for recording both cold and hot water) do not differ in wear resistance, so preference is given to typed analogues.
The service life of the devices is the period of time elapsed between the date of verification and the output of the meter. The date of verification is reflected on the case. After the expiry of the service life, the water meter changes to a new analog. When installing, it is important to follow the flow direction. On the counters, this parameter is indicated by an arrow. Otherwise, the reading will not be read correctly.
It is important to remember that the water flow meters show more accurate values if the water temperature is not more than 60 ° C, and the relative humidity in the room where the device is located is 98%.
When choosing a device, do not forget about the relevance of the manufacturers. Today, a considerable number of companies are engaged in the production of meters, both industrial and apartment. Among them are the real leaders. These include organizations such as Itelma, Triton, Betar and Arzamas. It is these companies that produce quite high-quality products.
Devices manufactured from the factories of these manufacturers are distinguished by their durability, reliability, excellent performance and strength. If there is a choice in the plans for a meter that will last a long time, then it is best to pay attention to the devices produced by the companies Italma and Arzamas. Their price is slightly higher, but the device will not be replaced soon, and this is not only economical, but also convenient.
All the owners of apartments have to decide what is best to put in the apartment with the approach of the verification period. There are the following types:
- Tachometric, or mechanical water meters - the maximum service life is 10-12 years. Principle of operation: a miniature turbine is placed in the flow of the substance and connected with the reading node. Among all the types of flowmeters, these have the simplest mechanism. They are affordable, compact, load-proof and perform accurate measurements. It is believed that the best water meters for the apartment are vane mechanical measuring instruments.
- Electromagnetic counters - are used in 84.3% of cases for industrial purposes. Principle of operation: in the electromagnetic coil, the flow of the substance produces a current whose magnitude is proportional to the velocity. Devices are characterized by high cost, complexity of service and high performance. Therefore, it is advantageous to supply this meter for calculating the consumption of communal-industrial waters.
- Ultrasonic devices are recommended for water accounting at enterprises, since these types of water are considered to be a full-fledged group of measuring instruments: powerful, productive and expensive. Principle of operation: measure the transit time of the ultrasound beam along the flow of the substance and against the flow and the velocity of the fluid in the tube.
There are still vortex water meters, but they are not recommended for installation in apartments. The purpose of such devices is the control and regulation of technical processes.
To determine which device to install in the apartment, you need to compare the water meters by type and by manufacturer. In addition, technical, operational and price characteristics of the measuring equipment must be taken into account. And they are 70% dependent on the manufacturer. The manufacturer will tell you which is better to put a meter on the water in the apartment - the most reliable companies are the following:
- - Italian water meters, verification period from 4 to 6 years.
- "Rosich" - the Russian manufacturer produces flowmeters with an operational period of 2 to 6 years.
- "Viterra" is a Canadian manufacturer, some of which have a service life of up to 10 years.
- "Elster Metronica" and (Germany) - meters are manufactured under the license of the Russian Federation.
- - Russian water meters for domestic and industrial use, produced separately for hot and cold water (universal models are few and their operational life is not more than 4 years).
There are other manufacturers, but listed above are in the top five. Suggest which water meters are better, consumer feedback or expert advice. It is more correct to apply to a commercial organization that performs installation and calibration of water meters to get a master's advice or personally go to the LCD service and ask there.
Help determine which water meter is best to install, those who have already used specific equipment in certain operating conditions. But still, rely solely on the opinion of neighbors or acquaintances is not worth it. It is better to approach the solution of the problem, which counter of water is best placed in the apartment, by acquaintance with the types of metering devices and their comparison (cost, functions, installation characteristics, inter-calibration interval, manufacturer and protection).
We remember: comparing water meters, determining which ones are better, reading reviews and listening to recommendations, do not forget that the one you like measuring device must be certified (approved by law) in the territory of the Russian Federation. Otherwise, it can not be registered at the ERRC.
A detailed description of water meters, or What type to choose?
Before determining which water meters are better, and which manufacturer to buy, you need to understand the flow meter classes. They are as follows:
- Mechanical devices - insignificant measurement error, small dimensions. The most popular winged water meters, which are better and reviews of their customers will be discussed below. There is also a division into single- and multi-jet. Multi-jet water meters are best, because these meters have more accurate measurements.
- Impulse equipment is a dry water meter, since its functional nodes and mechanisms do not come into contact with the substance. They have one significant advantage - the transfer of readings can be performed remotely. Finding out the question of which counter for water is better to buy by reading reviews about devices, it is worth considering that these types of measuring equipment are advantageous to install in apartments and houses where there is no access to a bathroom for the removal of accounting data.
- Electromagnetic variants - are manufactured in most cases for industrial purposes. But they can also be used to measure smaller volumes of electroconductive substance. Choosing which water meter is best to install, pay attention to the reliability of the equipment. Electromagnetic flowmeters are considered reliable and with proper maintenance serve for years.
Remember: there are also turbine models of devices, but they should not be taken into account when deciding which counters for water should be installed in the apartment. They are not installed in apartment buildings, as they are designed for pipelines of large dimensions (high capacity).
- way of installation - you can call a specialist from the LCD service or our company, which will prompt you which water meters should be placed in specific conditions;
- the diameter of the appliance (should correspond to the diameter of the water pipe in the apartment) - is indicated in the technical passport of the device, therefore, when choosing which water meters to buy, do not be lazy to look at the technical passport;
- capacity of equipment.
Remember: when deciding which water meter is best to install in the house, do not forget about the choice of the company that will perform the installation. Each type of device has its own installation features. For example, multi-jet instruments need to be installed using the right fittings, and if the owner of the apartment decides to buy a wing-type water meter, then it will be necessary to cut it into the pipeline. We need a really qualified specialist. Our company employs experienced craftsmen who can tell you which water meter is best to choose for specific operating conditions. 
Existing types of water meters, or Which flow meter will suit?
They are produced separately for hot and cold water. These water meters, which can be better chosen by the manufacturer, the calibration period and the price, work on the same principle. They are distinguished only by the operating temperature range:
- for a substance up to 400 ° C you need a flowmeter for cold water;
- for a substance up to 1200 ° C you need a water meter for hot water.
Reading reviews on water meters, deciding which is better, do not forget that the released volatile and non-volatile devices. The first type of equipment requires an additional installation of a power source. More often when deciding which water meters are better to put in the apartment, the owners choose the non-volatile form of the flowmeters. He does not stop his work when power is cut off.
Most popular water meters
Most often, the owners of apartments, faced with a dilemma, which water meter is better to buy, prefer:
- Tachometric (mechanical) flowmeters. If the cost of equipment is important, then the best water meters are just these. Wing models are suitable for pipes with a diameter of 40 mm (inclusive), and turbine - from 50 to 200 mm. Some manufacturers produce combined devices, but for their installation it will be necessary to call a specialist. When deciding which water meter is best to buy, note that tachometric models can have a life expectancy of 12 years (the maximum inter-calibration period, which is important). Also, choosing between the "wet" and "dry" device, note that in the first case the counting mechanism is located in the water. Therefore, the best water meters pulsed dry - the mechanism is not subject to the destructive effect of water.
- Electromagnetic devices. Slightly less popular devices due to higher cost. Finding out which counter is better for water, remember that it is electromagnetic models that are considered high-precision - determine the speed and area of the flow. The viscosity, degrees and density of the substance are not taken into account in the calculation. But there is one "but". In many respects, electromagnetic devices are the best counters for water, but customer testimonials say that they are faster out of order. The reason is low water quality indicators (chemical and physical composition of the substance).
