The Levelflex FMP55 multiparameter level transmitter can measure both the overall level of a liquid and the interface between two liquids. The FMP55 is the first transmitter to utilize two level technologies built into one probe, according to the manufacturer. 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 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. The level sensor has a measuring range of up to 33 ft. The transmitter offers a 4-20mA with HART output signal plus an optional second 4-20 mA output The FMP55 is ideal for interface measurement in the oil, gas and chemical industries. It can be used in process temperatures from -58 to 392 degrees F and in pressures from -14.5 to 580 psi. The FMP55 carries a SIL 2 rating as certifed by TÜV per IEC 61508 and has ATEX, IEC Ex, FM and CSA area classification approvals available.
