Water flow sensors (liquid)


Liquid flow sensors are widely used in technological pipelines of industrial enterprises, in the housing and communal services system for metering heat carriers and in other areas that require resource control. The devices are also irreplaceable in systems for automatic dosing of ingredients.

If necessary, a program can be installed on the sensor to check and calibrate the device. For data transmission, you can use a radio channel or wired networks.


  • Exceptional flow measurement accuracy with minimal error.
  • Reliable protection against polarity reversal and overvoltage.
  • Stable operation of the sensor around the clock.
  • Data transfer using an open protocol.
  • Autonomous power supply from a 4–8 V source.
  • Simple installation and use.
