Field of application

Micropilot FMR53 for simple level measurement applications in liquids. With its slim rod antenna, FMR53 free space radar is particularly suited for small process connections. The PTFE coating of the rod antenna and flange plating guarantee resistance also in aggressive media. The Micropilot FMR53 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.

Especially suited for small process connections, PTFE sensors usable in chemically aggressive media.

Process connections: Thread or flange
Temperature: -40 to +150°C (–40 to +302°F)
Pressure range: -1 to +40bar (–14.5 to +580psi)
Maximum measuring range: 20m (66ft)
Accuracy: ±6mm
C-band: 6GHz
International explosion protection certificates, overfill prevention WHG, SIL, 5-point linearity protocol

Benefits

Reliable non-contact measurement even for changing product and process conditions
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
Hardware and software developed according to IEC 61508 up to SIL3 (in homogeneous redundancy)
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
