The Micropilot FMR250 is ideally suited for tall silos and high temperature requirements also as for abrasive solids. The FMR250 has a integrated air purge connection for extremely dusty conditions or media tending to create build-up. Micropilot FMR250 performs continuous, non-contact level measurement especially in powdery to granular bulk solids. Dust, filling noises, temperature layers and gas stratification do not affect measurement.


  • Non-contact measurement: Measurement is almost independent from product properties

  • 2-wire technology, low price: A real alternative to differential pressure, floats and displacers.

    2-wire technology reduces wiring costs and allows easy implementation into existing systems

  • Easy commissioning, documentation and diagnostics via Endress+Hauser operating software

  • Easy on-site operation via menu-driven alphanumeric display

  • Used for level monitoring (MIN, MAX) up to SIL2 as per IEC 61508/ IEC 61511-1

  • HART or PROFIBUS PA respectively FOUNDATION Fieldbus protocol

  • Max. measuring range 70m (230ft)


Level measurement in tall silos with extremely dusty bulk solids e.g. cement, raw meal or animal feed. For applications with high temperature requirements up to +200°C (+392°F); e.g. clinker or fly ash. Applications with highly abrasive bulk solids e.g. ferrite. The FMR250 with DN80 or DN100 horn antenna for all standard applications, also for small nozzle sizes. With DN200 or DN250 parabolic antenna offers high beam focusing of 4°/3.5° and is thus ideal for applications with many installations.
