Endress+Hauser Levelflex FMP55 Interface Meter, Guided Wave Radar + Capacitance Fusion Technology (Emulsion Layer Special)

Levelflex FMP55 is a high-precision interface meter adopting sensor fusion technology, pioneered by Endress+Hauser, innovatively integrating capacitance measurement and guided wave radar technology to completely solve the interface measurement problem under working conditions with emulsion layers.

The device can continuously and stably obtain dual measurement values of liquid level and interface under complex working conditions with emulsion layers, unaffected by liquid level fluctuations, foam and medium changes. It has become a benchmark multi-parameter measurement product in the field of interface measurement, especially in the oil & gas, chemical and petrochemical industries.
