The Endress+Hauser Micropilot FMR60B is an 80GHz W-band non-contact radar level transmitter engineered for liquids, pastes, and slurries in storage tanks with internal obstructions like heating coils or agitators (-40 to +200°C, vacuum to 20 bar, max range 50m).
We provide factory-direct quotes, EN 10204-3.1 material certs, and beam angle calculation support within 24 hours.
In chemical reactors, water treatment basins, and food processing vessels, legacy 26GHz radar transmitters emit a wide signal beam (typically 10° to 15°). This wide microwave bounce strikes internal heating coils, ladder rungs, and rotating agitator blades, generating false high-level alarms that trigger premature filling valve shutoffs. Micropilot FMR60B eliminates these operational downtime hazards directly:
The specification table below outlines the mechanical, thermal, pressure, and electrical boundaries required by instrument engineers when selecting FMR60B for liquid storage and utility tanks.

Selecting between 80GHz radar models depends on process temperature, pressure rating, and chemical aggressiveness. The matrix below helps instrument engineers specify the correct unit without over-budgeting.
| Selection Parameter | Micropilot FMR60B (80GHz Basic Liquid) | Micropilot FMR62B (80GHz Severe Service) | Legacy 26GHz Radar (FMR51) |
|---|---|---|---|
| Operating Frequency | 80 GHz (W-band) | 80 GHz (W-band) | 26 GHz (K-band) |
| Beam Angle (DN80) | ~3° (Narrow Beam) | ~3° (Narrow Beam) | 10° to 15° (Wide Beam) |
| Max Process Temp | +200 °C (+392 °F) | +450 °C (+842 °F) | +450 °C (+842 °F) |
| Max Pressure Rating | 20 bar (290 psi) | 160 bar (2,320 psi) | 160 bar (2,320 psi) |
| Primary Application | Clean liquids, water/sewage, light chemicals, food paste | Extremely corrosive acids, high-pressure/temp reactors | Legacy utility tanks without narrow nozzle limits |
A: An 80GHz radar projects a much narrower beam angle (down to 3°) compared to a 26GHz radar (up to 15°). This narrow radar beam travels through small gaps between heating coils, pipe racks, and rotating agitator blades without striking them, preventing false echo signals and false high-level alarms.
A: Micropilot FMR60B is optimized for basic liquids, light chemicals, pastes, and food contact applications up to +200 °C and 20 bar. If your process involves extreme temperatures (up to +450 °C), pressures up to 160 bar, or highly aggressive acids requiring full PTFE drip-off antennas, specify the heavy-duty Micropilot FMR62B.
A: No. Every Micropilot FMR60B is factory-calibrated with a 5-point or 10-point inspection certificate. Once mounted and powered, you can quickly verify parameters via Bluetooth using the SmartBlue App or guided operation wizard without needing extra calibration equipment on site.
