Purpose and scope of the universal water meter with connectors, VSKM 90-25
Water meters VSKM 90-25 designed to measure the volume of network water according to SNiP 2.04.07 and drinking water according to GOST R 51232, flowing in supply or return pipelines of closed or open heat supply systems, cold and hot water supply systems in the temperature range from 5 to 120 ° C at a pressure of not more than 1 .0 MPa. The counters have a counting mechanism with roller and pointer indicators showing the measured volume in m 3 and its fractions.
Brief description of the universal water meter with connectors, VSKM 90-25
The principle of operation of vane meters is based on measuring the number of revolutions of the impeller rotating at a speed proportional to the flow rate of water flowing in the pipeline.
Structurally, the counter consists of a housing with a filter, a measuring chamber and a counting mechanism placed in a glass made of non-magnetic material.
Water meters VSKM belong to the so-called "multi-jet" type of devices, when water enters the impeller through holes in the guide, in which the impeller itself is located. This improves the measurement accuracy as well as the reliability of the water meter.

Accuracy
The multi-jet design is highly reliable. The impeller is located in a protective bowl, which divides the flow into several jets, which evens out the load on the impeller axis, thereby providing the best reading accuracy and protection against water hammer. All this affects the long-term correct operation of the devices.
Readout
The counting mechanism provides display of readings in m³ and its fractions. The front panel of the counting mechanism contains a scoreboard of 8 drums, with printed 6 mm numbers. A specially selected font of numbers allows you to accurately determine the meter readings from different viewing angles. The counting mechanism rotates 350 degrees, which maintains ease of use in any position and placement of the counter. In addition, the device has a special pointer metal indicator "MID-sensor" (in the version of the DG, the pointer is made of plastic). In addition, the counter can be equipped with a pulse sensor (DG).
Principle of operation
The principle of operation of the water meter is to measure the number of revolutions of the impeller rotating under the action of the flowing water. The number of revolutions of the impeller is proportional to the amount of water that has flowed. The rotation of the impeller is transmitted to the counting mechanism through a magnetic connection. The scaling gearbox of the counter adjusts the speed of the impeller to the values of the flowing water in m³ and its fractions.

Prices for metering devices vary depending on the brand, intellectual fillings and technical characteristics. PK Pribor, a Russian company, has been working in this segment for a long time and produces VSKM 90-15 water, its price is affordable, and the quality, in some respects, is higher than foreign ones. In particular, Russian flowmeters are better able to resist the magnetic field directed from outside.
Water meter VSKM 90-15, design and specifications
Water meters intended for individual housing, as a rule, have a tachometric principle of operation. The VSKM water meter does not differ much from its counterparts - it is a two-chamber device, where the counting device, placed in a transparent capsule, is separated from the meter operating in a liquid medium.
Fully sealed counting mechanism allows short-term immersion of the device in a liquid medium. In addition, dust and moisture do not get into the capsule, which prolongs the performance of the mechanism, which consists of many gears.
Visual reproduction of consumption data, made in the form of 8 digital windows with well-defined inscriptions. The ability to rotate the top chamber 360° creates additional convenience for users. That is why, VSKM 90-15 water meter, from consumers has mainly positive.
The impeller-shaped meter is made of durable plastic approved for production in the food industry. The rotational moment from the impeller is transmitted to the scaling gearbox of the counting mechanism in a non-contact way, by means of a magnetic coupling.
The body of the lower chamber is made of a brass alloy designed for precision machining. The high level of smoothness of the case and its additional coating with peel-resistant paint completely eliminates contact with drinking water harmful substances. The leading magnetic coupling half, placed in the "wet" chamber, is isolated from the influence of the magnetic field directed from the outside, with a special screen.
Operation of VSKM "Atlant" meters in automated systems of Moscow
Data accounting systems are being actively implemented in large cities. Despite the costs of its implementation, more and more residents of multi-apartment complexes are switching to automation of the transmission of flow meter readings and control over the state of engineering networks. It fits well into such systems - the VSKM 90-15 Atlant water meter, consumer reviews confirm this fact.
For successful integration of devices into the AU, the company produces water meters with a reed sensor and with a universal MID sensor. Water meters with a pulse output are equipped with a sealed contact that interacts with a magnet located on the water flow indicator. The outputs from the reed switch are connected to the storage module, data transmission from it can be carried out both by wire and by radio communication and other technical means. The contact impulse is adjusted to a certain volume of water that has passed through the meter. The impulse price varies from 1 to 100 liters and is set by the manufacturer.
The Pulse and Data Module (MID) is a sensor that, using inductance coils, takes into account the revolutions of the water meter pointer. On the arrow, as well as in the impulse version, a sensor is attached. Using a non-contact method, the sensor determines the number of turns of the pointer by changing the quality factor of the coils, due to the circular frequency of oscillation. The MID-sensor is installed on the counter in special sockets, without removing or disassembling the device.
Communication module MID, a self-sufficient element and remotely transmits data directly from the device, using the selected communication technology, to the base station. The built-in battery is designed for 8-9 years of continuous operation, and a stable signal is transmitted over a distance of up to 10 km. Moreover:
- due to non-contact rotation control, the sensor does not affect the measuring qualities of the device;
- simple installation of the device on front surface device;
- there is no clanging or rattling inherent in reed switches;
- recognizes the direction of water flow;
- additionally, it can collect information about abnormal operating conditions of the water meter.
VSKM 90-25 is suitable for house water metering units, its price is optimal and corresponds to the quality and reliability of the device. Our company, with a high level of competence, will conduct preparatory work, will install and put into operation a house unit that takes into account the water consumption at the input from the city network.

All prices for tachometric water meters are indicated in rubles (see the general price list) excluding tax (VAT = 18%), the cost of additional equipment, packaging, shipping and / or delivery costs, based on a small wholesale order (with for large wholesale lots and for project orders, the price is formed individually, based on the size of the lot, the agreements reached and the address of the object).
ATTENTION! Be careful when choosing a supplier - there are cheap low-quality copies of tachometric meters for cold and hot water on the flow metering market: analogues, fakes and illiquid assets, devoid of proper service, guarantees, with shorter or expiring verification periods, not included in the database, without additional options, mounting connecting parts; therefore, perhaps even having a lower price.
