The Endress+Hauser Micropilot FMR63B is an 80GHz W-band hygienic radar level transmitter engineered for liquid level measurement in food, beverage, and pharmaceutical sanitary tanks (-40 to +200°C, vacuum to 25 bar, max range 80m).
The Endress+Hauser Micropilot FMR63B is an advanced 80GHz W-band hygienic radar level transmitter designed for food, beverage, and bio-pharmaceutical engineers who require non-contact level accuracy without batch cross-contamination. Featuring a narrow 3° beam angle, ±1 mm (0.04 in) system accuracy, and full compliance with 3-A, EHEDG, ASME BPE, and USP Class VI sanitary standards, the FMR63B delivers continuous level monitoring up to 80 meters (262 ft) in active fermentation tanks, mixing reactors, and storage vessels.

Traditional 26GHz radar transmitters emit a wider beam angle (10° to 15°), which frequently collides with internal tank obstructions such as agitator blades, heating coils, baffles, and ladder rungs. These obstructions reflect strong false signal echoes, causing false high-level alarms or pump shut-offs.
The Micropilot FMR63B 80GHz radar frequency focuses signal energy into a narrow 3° beam. This tightly concentrated radar signal travels cleanly through narrow installation nozzles and bypasses rotating mixer impellers to strike the liquid surface directly. Engineers no longer need to spend hours configuring manual false-echo suppression curves, ensuring reliable level tracking even during high-turbulence mixing processes.
In bio-pharmaceutical and dairy processing, traditional contact probes and hydrostatic level transmitters create dead legs and crevices where organic media accumulates, promoting bacterial growth. Furthermore, rapid Clean-in-Place (CIP) chemical washes and Steam-in-Place (SIP) sterilization at +135°C to +200°C cause thermal expansion that damages standard transmitter seals.
The FMR63B features a flush-mounted PEEK/PTFE antenna surface designed according to strict ASME BPE, 3-A, and EHEDG hygienic guidelines. With no dead spaces, non-contact measurement prevents product adhesion and enables complete cleanability during CIP/SIP sequences. The hermetically sealed antenna construction withstands extreme temperature transitions without seal degradation or vacuum leakage.
Uncalibrated sensor drift during pharmaceutical batch processing can ruin thousands of liters of product. The FMR63B integrates Endress+Hauser Heartbeat Technology, offering continuous online self-diagnostics, internal reference checks, and real-time accuracy monitoring without interrupting process flows.
Follow this 3-step decision flow to verify if the Micropilot FMR63B fits your process container requirements:
| Performance Criteria | Micropilot FMR63B (80GHz Non-Contact Radar) | Levelflex FMP54 (Guided Wave Radar / GWR) |
|---|---|---|
| Measurement Style | Non-contact 80GHz FMCW beam | Direct contact probe/cable immersed in liquid |
| System Accuracy | ±1 mm (0.04 in) | ±2 mm (0.08 in) |
| Sanitary Cleanability | Flush antenna; zero dead space; effortless CIP/SIP | Probe rod requires manual cleaning and CIP validation |
| Agitator Mechanical Risk | Zero risk (sensor remains completely outside fluid) | High risk (mixer force can bend or snap probe rods) |
| Installation / Retrofit Cost | Low (mounts directly to top Tri-Clamp nozzle) | Moderate (requires full vertical clearance for probe) |
Before installing or retrofitting the Micropilot FMR63B onto existing hygienic processing tanks, review these crucial installation parameters:
A: The 80GHz W-band FMCW radar operates with a narrow beam angle down to 3 degrees (compared to 10-15 degrees in legacy 26GHz radars). This tight signal focus directs microwave energy past internal mixer blades, heating coils, and baffles directly to the liquid surface, eliminating false echo reflections without requiring complex suppression mapping.
A: Yes. The Micropilot FMR63B is engineered specifically for Clean-in-Place (CIP) and Steam-in-Place (SIP) thermal cycles up to +200°C (+392°F). Its flush-mounted PEEK and PTFE wetted parts comply with ASME BPE, 3-A, and EHEDG standards to ensure zero dead legs and prevent seal deterioration under rapid thermal shocks.
A: Heartbeat Technology provides continuous online self-monitoring, self-calibration, and SIL 2/3 diagnostic coverage (IEC 61508) without interrupting active processes. It detects signal drift and antenna buildup early, allowing maintenance teams to verify instrument health and print audit-ready verification reports without stopping production.
A: The FMR63B reliably measures liquids with dielectric constants as low as εr ≥ 1.1. For ultra-low dielectric media such as purified water or liquefied gases, smart echo-tracking algorithms via the SmartBlue Bluetooth app ensure stable signal reflection.
