Anyone who does not have his own well, has to install a water meter that records the number of transferred cubic meters. Such devices are mounted in the pipeline at the entrance to the building or installed in each apartment and house separately. The devices are divided according to the principle of operation into wing, turbine and ultrasonic. Metering devices differ in size, case materials, and ease of reading and transmission of readings. The rating of the best water meters collected goods for counting hot and cold water in apartments, appliances for home and summer cottage, devices for commercial accounting at enterprises and institutions with a large number of employees.
The best apartment water meters
Apartment called meters working with a rotating impeller inside. They are compact and simple, which allows them to be installed in niches or directly in the bathrooms of apartments.
Such water meters are used in private houses, as well as small office buildings with a small number of employees.
ITELMA WFK20.D080 Du = 15mm - with resistance to overpressure
This is the best meter for cold water in an apartment or a private house, because it has increased strength to mechanical loads and fluid pressure from the inside.
The body is made of brass that can withstand water pressure up to 10 atmospheres, which ensures tightness between distillation and reading chambers.
The model has a white screen, which clearly shows a red rotating arrow and the work of a black star, duplicating the action of the impeller.
Pros:
- the stainless case will withstand wet conditions not only in the bathroom, but also in the water gauge;
- minimum threshold of sensitivity (8 liters per hour);
- low error;
- nickel was not involved in production;
- stable readings regardless of meteorological conditions;
- it is allowed to mount both horizontally and vertically;
- cost from 750 rubles;
- before the point of attachment and after the exit smooth sections of the pipe are not required (it is possible to rotate as conveniently as communications and create angles);
- production in Russia, but under a German license with European components;
- 4 year warranty;
- temperature run-up of flowing fluid from 5 to 30 degrees;
- short installation length 80 mm;
- Lightweight 420 g is optimal for plastic plumbing.
Minuses:
- both the dial and the surrounding surface are white, which makes the thin digits of the display poorly visible from a distance;
- if part of the pipe to the meter passes in the house next to heating devices (boiler, radiator), then due to temperature increase, the readings may deviate from reality.
Decast VSKM 90-15 - with pulse output
This is the best water meter for an apartment or a small building that facilitates the collection and transmission of readings. In its design, a sensor is installed, sending a pulse and fixing the spent cubic meters.
The sensor signal can be output to external devices and process data remotely, which is practical when the counter is located in a basement or other remote location. The upper plastic part rotates 360 degrees and turns around for easy reading of the indications by visual means.
Pros:
- cost from 800 rubles;
- maintains and correctly reads the readings of a liquid with a temperature of up to 120 degrees;
- can be mounted in closed and open systems;
- easy installation due to common standard input ¾;
- service life up to 12 years;
- pulse output facilitates data collection;
- brass body is durable and not subject to corrosion;
- small installation length 110 mm;
- weight of 500 g will not create loads on plastic communications;
- the body is covered with paint on the outside, which enhances the aesthetic appearance;
- protection from external magnetic effects;
- the coupling and the counting mechanism are separated by a hermetic partition;
- This model requires verification once every 6 years.
Minuses:
- when visually reading, the indication is poorly visible because of the white background of the wheels with numbers and the white dial;
- when running on hot water, the filter clogs faster, which will require periodic disassembly and cleaning.
Top Turbine Water Meters
This type of metering of cold and hot water is mounted on the input line to the building. Inside is a turbine that rotates like an impeller.
The device is designed to transfer large amounts of water, so the main area of application is industrial and commercial large objects.
Heat meter VSHN DU 50 - maintains elevated temperature
This is the best water meter for a company or an office building with a large number of personnel due to the carrying capacity of 45-90 m3 per hour. The device is suitable for supplying network water and even drinking.
The body is made of cast iron and has a reinforcement that makes it resistant to mechanical loads. The dial screen is protected by a hinged lid. Four bolts and an opening hatch on top are provided for the repair.
Pros:
- if part of the pipe is exposed to heat, this does not affect the correctness of the readings, because the device is designed for a temperature range from 5 to 50 degrees;
- verification interval is allowed once in 6 years;
- the threshold of sensitivity is lower than that of household models and is 0.15;
- simple and reliable connection to the line through the flanges;
- compact length 200 mm;
- installation on the giving or return pipeline is allowed;
- can be used on drinking water.
Minuses:
- cost from 9700 rubles;
- 1.5 year warranty;
- a mass of 10 kg is inconvenient during installation and requires a secure fit on the pipe.
The water control unit BMX DU 200 - impressive throughput
This is the best water meter for a huge enterprise, as it is capable of flowing up to 1000 cubic meters of water per hour. Cast iron housing is resistant to corrosion and stress.
The white dial is edged with a plastic black frame and covered with a strong lid. Designed device for cold water. The assembly is sealed, so installation is allowed, even in flooded areas.
Pros:
- can be mounted in open and closed systems;
- corresponds to meteorological class B;
- 1.5 threshold of sensitivity for this volume is optimal;
- compact length 300 mm;
- installation through a flange with gasket;
- it is possible to connect the reader and remote reading;
- 6 years warranty;
- increased turbine life;
- open protocol;
- the ability to mount in any pipeline at an angle of inclination.
Minuses:
- cost from 32,000 rubles;
- The weight of 51 kg needs to be firmly fixed and inconvenient during installation;
- suitable only for cold water.
Best Ultrasonic Water Meters
Devices of this type let the ultrasound through the flow of water, which has its own speed of passage, depending on the strength of the fluid flow.
This method is used where very accurate readings are needed or in places where it is impossible to connect another device due to its large physical parameters.
PULSAR DU-15 RS 485 - with digital output
This is the best water meter for a limited space, since the module itself with an ultrasonic sensor is very small and takes up a little more space than the diameter of the pipe.
Wires are retracted from it and consumption data is already shown on the digital module. The screen can be taken to any convenient place. The readings are archived in the base of the device.
Pros:
- possibility of remote data retrieval;
- simple installation, which requires a minimum of space;
- the device shows the presence of a leak;
- automatic recognition of flow direction;
- synchronization of readings from several counters;
- capacity up to 3 m3 per hour;
- maintains pressure in 1,6 MPas;
- error not exceeding 2%;
- maintains water temperature up to 90 degrees;
- creating an archive with memory for 1080 hours;
- in the design there are no moving mechanical components that are erased or wear;
- service life of about 20 years;
- You can connect the dashboard at a distance of 1200 m from the pipe.
Minuses:
- cost from 10500 rubles.
