Field of application
Micropilot FMR50 is the best choice in simple reservoir and storage applications as well as in utility processes. The FMR50 free space radar 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 with SmartBlue app via Bluetooth module is available.
Encapsulated PVDF or PP-plated horn antenna.
Process connections: Thread, mounting bracket or slip-on flange
Temperature: -40 to +130°C (-40 to +266°F)
Pressure: -1 to +3bar (-14.5 to +43.5psi)
Maximum measuring range: 30m (98ft), 40m (131ft) for enhanced dynamics
Accuracy: ±2mm
K-band: 26GHz
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
