Flow transmitters / flow switches

Flow transmitters / flow switches

HYDAC ELECTRONIC offers a different of flow rate measuring transmitters and flow switches for recording the flow rate in machines and plants.

The flow rate measuring transmitter of the EVS 3000 series works in accordance with the turbine principle (recording the rpm of an impeller wheel rotating in the media flow). Depending on the version, additional connection openings for pressure and/or temperature transmitters are available.   The flow switches/flow transmitters of the HFS 2000 / HFT 2000 series are based on the buoyancy transmitter measurement principle.     Electronic flow rate transmitters for general applications:

  • EVS 3100 (for oils/viscous fluids)
  • EVS 3110 (for water-based media)
  • HFT 2100 (for oils/viscous fluids)

  Electromechanical flow rate switches for general applications:

  • HFS 2100 (for oils/viscous fluids)
  • HFS 2500 (for water/water-based fluids)
  • HFS 250 (for water/water-based coolants)


 Electronic flow rate transmitters for applications in explosive atmospheres:

  •  HFT 3100 (flameproof enclosure)
  • HFT 3110 (intrinsically safe design)
