Flow Measurement

Electromagnetic Flow Meter


Electromagnetic flow meter efs802e


Electromagnetic flow meter iSOLV EFS802E offers accurate, reliable and stable flow measurement of liquids in HVAC Systems. It can display both instantaneous and cumulative flow, and supports analog output, MODBUS communication output and relay control functions.

EFS802E features reduced bore type flow sensors, eliminating the need for straight pipe run, making installation convenient.

  • EFS802E provides reliable flow measurement for conductive fluid > 5mS/cm.
  • Process medium temperature, viscosity, density has no influence on the flow measurement.
  • Flow sensor is maintenance free, no moving part and straight through flow tube (no pressure loss).
  • Reduced bore flow meter (up to DN300) with U0D0 (straight pipe length) installation

Applications for the Electromagnetic flow meter EFS802E includes:

  • AHU (Air Handling Unit)
  • FCU (Fan Cooling Unit)
