E+H Micropilot FMR57 Premium Bulk Solids Radar Level Transmitteritter

Precision Non-Contact Level Measurement for Heavy Bulk Solids

In heavy process industries such as mining, cement manufacturing, power generation, and bulk grain storage, accurate continuous level measurement in tall silos and bunkers is essential for inventory management and preventing costly vessel overfills. The Endress+Hauser Micropilot FMR57 Non-Contact Radar Level Transmitter represents top-tier radar engineering designed specifically for challenging bulk solids applications. Utilizing non-contact ~26 GHz pulse radar technology, the FMR57 measures solid material surfaces continuously without mechanical contact, eliminating cable snapping risk, tensile loading, and mechanical wear associated with traditional guided wave or electromechanical devices.

Parabolic Antenna & Air Purge for Extreme Dust Environments

Measuring bulk solids in tall silos with steep angles of repose, internal structural obstacles, or heavy airborne dust created during pneumatic filling often causes severe signal attenuation. The Micropilot FMR57 overcomes these challenges by offering a high-gain parabolic antenna (200 mm / 8”) or horn antenna with an integrated swivel flange.

The parabolic reflector creates a highly focused, high-energy radar beam that penetrates heavy dust clouds and concentrates energy on uneven material slopes. Furthermore, the antenna features an integrated compressed air purge connection, continuously preventing fine dust, fly ash, or sticky powder from accumulating on the antenna emitter face.

Multi-Echo Tracking & Safety Functional Integrity

Vessels with internal support trusses, ladder rungs, or filling streams create false radar reflections that can disrupt level tracking. The FMR57 incorporates Endress+Hauser Multi-Echo Tracking software algorithms, which automatically identify, map, and suppress static internal obstructions to maintain locked tracking on the true material surface reflection across the entire 70-meter range.

Designed according to IEC 61508 standards, the FMR57 is certified for safety instrumented systems (SIL2 / SIL3 in homogeneous redundancy). Integrated onboard diagnostic functions continuously monitor sensor health and signal quality, providing immediate diagnostic feedback conforming to NAMUR NE107 standards.

Flexible digital communication interfaces include 2-wire 4 to 20 mA HART, PROFIBUS PA, and Foundation Fieldbus protocols, allowing seamless automation integration into plant PLC, SCADA, or DCS networks.

FAQ

Q1: Is the Endress+Hauser Micropilot FMR57 supplied as an authentic original unit? A: Yes. We supply 100% genuine, brand-new Endress+Hauser instruments complete with original factory serial numbers, calibration reports, and official documentation.

Q2: What is the benefit of the parabolic antenna and swivel flange option on the FMR57? A: The parabolic antenna focuses the 26 GHz radar beam to penetrate heavy dust clouds and reach deep into tall silos (up to 70 m). The swivel flange allows operators to mechanically align the antenna perpendicular to the material slope for optimal signal return.

Q3: Can the FMR57 withstand high process temperatures in cement or ash silos? A: Yes. The FMR57 offers high-temperature process connection extensions capable of handling process temperatures up to +400 °C (+752 °F), making it suitable for hot clinker and fly ash applications.

Q4: How can I request distributor quotes and confirm delivery lead times? A: Simply submit your required E+H model ordering code, silo height, process material type, and flange specifications through our inquiry form. Our sales team will provide a prompt, competitive quotation and export delivery timeline.
