E&H Micropilot FMR51 Radar measurement Time-of-Flight

Micropilot FMR51 for level measurement even under extreme process conditions like high temperature and high pressure in the oil & gas and chemical industry. The FMR51 free space radar offers maximum reliability due to an innovative and patented sensor-design. Micropilot is used for continuous, non-contact level measurement of liquids, pastes, and slurries. The measurement is not affected by changing media, temperature changes, gas blankets or vapors. Remote access via the SmartBlue app is available.

  • Hardware and software developed according to IEC 61508 up to SIL3 (in homogeneous redundancy)
  • HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics
  • Highest reliability even in the presence of obstructions in the vessel due to new Multi-Echo Tracking evaluation
  • 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 concept for SIL and WHG saves time and cost
  • Highest safety due to double ceramic coupling and gas-tight feedthrough
