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.

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 protection WHG, SIL, marine approvals

Benefits

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 digital communication you can initiate the device for a fast and easy testing of the safety loop.
Heartbeat Technology allows safe, continuous diagnostics and a simple verification, without process interruption
Centralized asset management with easy online access to all device information thanks to digital communication
Second line of defense to protect the environment

Videos

Preventive maintenance is possible with corrosion detection via Heartbeat Technology
Liquiphant with permanent function check is the safe choice for point level detection in liquids
