HFT 2500 for Water / Water-based Media


The HFT 2500 series of HYDAC flow transmitters is based on the variable area float principle and is position independent.

The test medium deflects a spring loaded float in the direction of flow, depending on the flow rate but irrespective of the installation position. A Hall sensor is fitted to the outside of the device and is therefore also outside the flow circuit. It determines the position of the float.

The sensor emits an analogue signal proportional to the deflection of the float which corresponds to the relevant measurement range.

The calibration of the device is for vertical installation and for a flow direction from bottom to top.

Areas of application are to monitor flow rate in fluids (water / water-based) in the following areas, amongst others:

  • Cooling systems and circuits
  • Hydraulic systems
  • Pumps
  • Welding machines and laser systems
  • Medical technology
  • Pharmaceutical industry
  • Chemical industry
  • Research & development



  • Water or water-based media



  • Accuracy ≤ ± 3 % FS
  • Any mounting position
  • High level of functional reliability
  • High-pressure resistance
  • Threaded connection
