Electronic water meter

Electronic water meter 1/2" - Уточняйте To order

Electronic water meters "Pulsar" are designed to measure the volume of cold or hot water flowing in pipelines of cold and hot water supply systems.

The principle of operation of the counter is to measure the number of revolutions of the impeller rotating under the action of the flow of flowing water. The counter has an electronic impeller speed sensor. The signal from the sensor goes to a microprocessor device, which calculates the volume of water that has passed through the meter. The volume value is displayed on the indicator device.

To transfer the results of measuring the volume of water to external information systems, the meters can be equipped with: a pulse output (including with the definition of a reverse stroke); digital output RS 485; M – Bus output; radio modules IoT, NB-IoT, LoRaWAN and WM-BUS.

  • Pressure of the measured medium, MPa, no more than: 1.6;
  • Permissible error in the range Qt ≤ Q ≤ Qmax, %: 2%;
  • Permissible error in the range Qmin %: 5;
  • Maximum temperature of measured water of cold water meters, ºС: from 0 to +40;
  • Maximum temperature of measured water by hot water meters, ºС: from 0 to +95;
  • Radio module frequency in the range, MHz: 433.075 ... 434.479;
  • Pressure loss at maximum flow rate, MPa, no more than: 0.1;
  • Archive depth: hourly - 1488, daily - 184, monthly - 60.
