Product Description

Comprehensive Technical Report: E+H Micropilot FMR51 Radar Level Transmitter
1. Product Overview
The Endress+Hauser Micropilot FMR51 is a high-performance, non-contact radar level transmitter designed for extreme industrial applications in sectors such as oil & gas, chemical processing, pharmaceuticals, and environmental technology. Utilizing 26 GHz K-band radar (frequency-modulated continuous wave, FMCW), it delivers precise (±2 mm accuracy) and reliable level measurements for liquids, pastes, and slurries under challenging conditions, including high temperature (up to +450°C), high pressure (up to 160 bar), and corrosive environments
Its robust construction ensures compliance with international safety standards, including SIL 2/3 and WHG overfill prevention.

2. Measurement Principle
Based on the Time-of-Flight (ToF) principle, the FMR51 emits microwave pulses toward the medium surface. The device calculates level by measuring the time delay between transmitted and reflected signals. Advanced Multi-Echo Tracking technology filters interference from vessel obstructions (e.g., agitators, pipes), ensuring consistent accuracy even in complex geometries. The 26 GHz frequency enables a narrow beam angle (e.g., 4° for 100 mm horn antenna), minimizing false echoes and enhancing signal focus .
