How to choose a water meter?
To buy a water meter today they want bothowners of apartments and private houses. After all, this device allows you to monitor the consumption of water and, if necessary, save. Currently, manufacturers offer a variety of water meter options. But how to choose a water meter among all the variety? Today we will talk about this.
Which water meter to choose
Buying a water meter, be sure to pay attention to such characteristics as:
- Company manufacturer.
- Verification interval time.
- Guarantee period.
- The installation size of the device.
- The cost of the device.
- Service support of the manufacturer.
Water meters are divided according to the principleactions on: mechanical (turbine and vane), electromagnetic, ultrasonic, vortex. The water meter needs electrical power to operate, so the meters are also divided into those that depend on electricity and are non-volatile. Energy-dependent meters take electricity from an external power grid. In the design of the same non-volatile counters, there is a power source - a battery.
Mechanical counters account for the flow rate ascold, and hot water. Distinguish the material from which the impeller and bearings are made. The temperature of the hot water measurement is 130-150 degrees, the cold temperature is up to 40 degrees. Other types of water meters can be used for both cold and hot water measurement.
If you need a water meter in your apartment, then,often, establish a household. For industrial facilities and industrial purposes, industrial counters are used. These meters differ in the conventional diameter of the counter. For the apartment use a water meter, whose diameter is from 15 to 25mm. To account for water in communal and industrial water supply, install meters, whose diameter is 25-400mm. In addition, (depending on additional design features), all water meters are divided into turbine, multi-jet, single-jet.
When calculating the water flow, a multi-jet counteris considered more accurate. However, it costs an order of magnitude more than a single-jet one. "Wet" water meters (where the counting device is not separable from the water flow) are the simplest and most effective in the process of use. In "dry" water meters, water separates from the mechanism by a partition. There are also combined water meters, which combine vane and turbine meters.
