Field of application

The Liquiphant FTL51B is specialized for the process industry and already developed according to IEC 61508 to be used directly in SIL2 and SIL3 applications without big efforts. You conduct periodic proof tests according to SIL or WHG simply mobile with an intuitive wizard. At the end you receive an automated documentation.
Liquiphant measures reliably and is not affected by changing media properties, flow, turbulences, gas bubbles, foam, vibrations or build-up.

Point level switch with extension tube for all liquids

  • Process connections: Threads, flanges and hygienic process connection (Tri-Clamp)

  • Temperature: -50 to +150°C (-58 to +302°F)

  • Pressure: -1 to +100bar (-14.5 to +1450psi)

  • Sensor material: 316L, Alloy

  • International explosion protection certificates, overfill prevention WHG, SIL, marine approvals


  • Universal measuring principle for limit detection – proven vibronic technology

  • Developed according IEC 61508 for highest safety – SIL2/3 applications (3rd party approved)

  • Periodic proof testing is quickly and simple organized with guided wizards via the SmartBlue-App or via a test button or magnetic pin from outside. Via these ways, you can initiate the instrument for a fast and easy testing of the safety loop

  • Heartbeat Technology allows safe, continuous diagnostics and a simple verification

  • Heartbeat Diagnostics: Permanent diagnostics increase the safety of the plant. You connect your device via the SmartBlue-App and you easily have real time diagnostics at hand

  • Heartbeat Verification: The device can be verified without process interruption. The verification report is generated automatically

  • Heartbeat Monitoring: With the frequency tracking of the sensor data you have all information at hand for predictive maintenance and process optimization strategies
