E+H Levelflex FMP50 Guided Radar Transmitter

Levelflex FMP50 is the instrument for basic applications in liquids which do not place high demands on temperature and pressure ranges or chemical resistance. Particularly in basic supply or storage applications as well as utility processes FMP50 is the best choice. Levelflex FMP50 guided radar is used for continuous level measurement of liquids, pastes and slurries. The measurement is not affected by changing media, temperature changes, gas blankets or vapors.

  • Reliable measurement even for changing product and process conditions
  • HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics
  • Highest reliability due to new Multi-Echo Tracking evaluation
  • Hardware and software developed according to IEC 61508 up to SIL3
  • Heartbeat Technology for a cost-effective and safe plant operation during the entire life cycle
  • Seamless integration into control or asset management systems and intuitive, menu-guided operation concept (on-site or via the control system)
  • World’s easiest proof test for SIL and WHG saves time and costs
