Radar measurement Time-of-Flight Micropilot FMR51

The standard sensor for highest demands in liquid level measurement

Micropilot FMR51 for level measurement even under extreme process conditions like high temperature and high pressure in the oil & gas and chemical industry. TheFMR51 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.

Benefits

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
Seamless integration into control or asset management systems
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 gastight feedthrough
