The Levelflex FMP55 multiparameter level transmitter can measure both the overall level of a liquid and the interface between two liquids. It utilizes two level technologies built into one probe. The transmitter will automatically switch between the technologies in order to provide a concise and reliable interface measurement, even in the presence of emulsion or rag layers. The use of two technologies eliminates many problems associated with interface level applications. The FMP55 is ideal for interface measurement in the oil, gas and chemical industries.
