Application Area
The Micropilot FMR53 is designed for straightforward liquid level measurement tasks. Its compact rod antenna makes the FMR53 radar ideal for small process connections. The PTFE-coated antenna and flanges ensure resistance to aggressive media. The device is used for continuous, non-contact measurement of liquids, pastes, and slurries. Measurement accuracy remains unaffected by environmental changes, temperature fluctuations, gas layers, or vapors.
Optimized for small connections, PTFE sensors resist chemically aggressive environments.
