Liquiphant T FTL20H

Level Switch · Automation & Control

Class-certified type (DNV register) · technical data sheet not yet verified

Liquiphant FTL20H is a point level switch with compact hygiene design for use in storage tanks, agitators and pipes which have to meet particularly high hygiene standards internally and externally. FTL20H can be used as an overfill prevention or as a pump dry-run protector. The measurement is unaffected of viscosity, build-up, turbulences, flows, air bubbles or temperature changes during cleaning. Functional check in installed state from the outside possible. EHEDG approval available.

Free of charge — send us your request for Endress+Hauser equipment. Our team checks it and replies by e-mail.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
