The Levelflex FMP55 multiparameter level transmitter can measure both the overall level of a liquid and the interface between two liquids. The transmitter 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. 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. The level sensor has a measuring range of up to 10m. The transmitter offers a 4-20mA with HART output signal plus an optional second 4-20mA output With its coated multiparameter probe, the device is suited for interface measurement in the water and wastewater industries. It can be used in process temperatures from -50 to 200ºC and in pressures from -1 to 40 bar. 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. All of the setup parameters are stored on the HistoROM and, in the event of an electronics change-out, all of the information will be uploaded directly into the new electronics module, information can be transferred into a display that can be removed and installed in another transmitter Three different setup methods are offered for the FMP55: with the removable display, via the three buttons on the display itself or through the free FTD-based FieldCare.
