Request Information

The Liquiphant FTL31 is a vibronic point level switch for liquids. The device is used for overfill prevention or pump dry-run protection in cleaning systems. The measurement is not affected by conductivity, build-up, turbulence, flow or air bubbles and does not require calibration. The optional IO-Link capability allows easy and time-saving configuration.

Key Benefits

  • The FTL31 works in areas where other measuring principles are not suitable due to conductivity, build-up, turbulences, flow conditions or air bubbles.
  • Smallest vibronic sensor on the market.
