The Liquiphant is a level limit switch for all liquids. It can monitor the upper and lower level limits in tanks and vessels and is suitable for all liquids •with temperatures lying between –40 °C and +150 °C (–40 °F and +300 °F) •with a viscosity up to 10.000 mm 2/s (cSt) •with a density greater than 0.5 g/cm 3
Liquiphant M FTL50(H), FTL51(H) Endress+Hauser 5 Electronic versions FEL51: Two-wire AC version; Switches the load directly into the power supply circuit via an electronic switch. FEL52: Three-wire DC version; Switches the load via the transistor (PNP) and separate connection e.g. in conjunction with
The Liquiphant FTL31 is a point level switch for liquids and is used in tanks, vessels and pipes. It is used for overfill prevention or pump protection in cleaning and filter systems as well as in cooling and lubrication vessels, for instance.
