Liquid level switches

Liquid level float switch is available with one or several switching points. The DFL float level switch has an integrated datalogger and parameters are set via an NFC Andriod app. The TFS-models are available with integrated PT1000 temperature sensor or thermostat as option.

  • Wide range of chemical and corrosive resistant materials.
  • One or several switch points.
  • Wide range of process connections, top mounted or side mounted.

Conductive level probes for liquid with a conductivity of min. 5µS/cm. No moving parts in contact with the liquid. Adjustable switching delay to compensate for foam on the surface.

Optical level switch is a very compact solution with minimal footprint in the tank and no moving parts.
