Endress Hauser Vibronic Point Level Detection Liquiphant FTL50 FTL51 FTL51B FTL51C FTL62 FTL64 FTL70

The Endress+Hauser Liquiphant FTL51B is a highly reliable vibronic point level switch engineered for accurate liquid level detection in industrial processes. As part of the new-generation Liquiphant series, the FTL51B integrates Heartbeat Technology, enhanced diagnostics, and superior digital communication to maximize safety, efficiency, and system uptime.

Designed for demanding environments, the FTL51B performs consistently in all types of liquids—regardless of density, viscosity, conductivity, foam, or turbulence. It is widely applied in chemical plants, energy systems, water treatment, oil & gas, and general process industries for overfill protection, dry-run protection, and safety-critical control loops.
