Level Transmitter Measures Level, Interface Between Two Liquids

April 11, 2011

The Levelflex FMP55 multiparameter level transmitter can measure both the overall level of a liquid and the interface between two liquids. 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. Capacitance is not affected by emulsion or rag layers in interface applications, and the radar allows the transmitter to monitor the overall level as well as the interface level. The transmitter has a multi-echo tracking algorithm that can track up to 20 tank echoes simultaneously as the tank level rises or lowers. This ensures that the transmitter will not make a "jump" to an echo that is not the true level, such as a internal tank obstruction or heater coils.
