Field of application

The Liquiphant FTL51B is specialized for the process industry and developed to be used directly in SIL2 and SIL3 applications. You conduct periodic proof tests according to SIL or WHG 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. The device is easy to use, has a digital connection and gives real-time data at hand.
