Endress+Hauser Levelflex FMP52 – Guided Radar Level Transmitter for Aggressive Liquids
The Levelflex FMP52 is a premium guided radar level transmitter specially designed for continuous level measurement and interface measurement in aggressive liquids. Featuring a chemically resistant PFA-coated probe, the FMP52 provides reliable measurement performance in applications where conventional level instruments may be limited by corrosion, chemical attack or demanding process conditions.
Based on the proven time-of-flight guided radar principle, the FMP52 delivers stable measurement even when process conditions change, including variations in media properties, temperature, gas blankets, vapors or moving surfaces.
Reliable Guided Radar Measurement Without Process Interruption
The Levelflex FMP52 sends high-frequency electromagnetic pulses along the probe. When the signal reaches the medium surface or interface layer, part of the energy is reflected back. The transmitter calculates the level based on the measured travel time.
Because the measurement is guided along the probe, the FMP52 provides excellent signal reliability even in tanks with challenging conditions such as foam, vapor or turbulent surfaces.
