Endress+Hauser Levelflex FMP54

High-temperature and high-pressure level measurement for extreme processes

Endress+Hauser Levelflex FMP54 high temperature high pressure guided wave radar

Levelflex FMP54 is a premium guided wave radar level transmitter for continuous measurement in extreme process conditions. It is designed for high-temperature and high-pressure applications in the oil and gas, chemical and power industries.

Engineered for extreme service: process temperatures up to +450 °C and pressures up to 400 bar, with optional gas phase compensation for demanding steam and high-pressure applications.

Why choose the Levelflex FMP54?

  • Reliable guided radar measurement under extreme temperature and pressure

  • Rod, rope and coaxial probe options for different vessel geometries

  • Gas phase compensation option for steam boiler and high-pressure applications

  • High measurement accuracy for stable process control

  • HistoROM data management, Multi-Echo Tracking and Heartbeat Technology
