Field of application

Liquiphant FTL62 has a strong focus on specific applications with aggressive liquids and simplicity with easy proof testing, reliability and safety (SIL) with compliance to IEC 61508, API 2350 and WHG. The vibronic device is determined for a safe and active measuring technology in aggressive liquids and want a reliable and proven point level detection for tank overfill protection and pump dry run protection. The FTL62 is easy to use, has a digital connection and gives a real-time data at hand.

Point level switch with extension tube for pumpable liquids

Coated sensor for aggressive media: ECTFE (Halar), PFA (EdlonTM, Ruby Red, conductive), Enamel
Process temperature: -60 °C to +150°C
Process pressure: -1 to +40bar
Ambient temperature: -60 to +70°C
Viscosity up to 10,000mm2/s (cSt)
Process connections: Flanges
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
