Level Transmitter uses 2 level technologies in one probe.
April 8, 2011 -
Using both capacitance and guided wave radar technologies, Levelflex FMP55 measures overall level of liquid and interface between 2 liquids. Unit will automatically switch between technologies to provide concise interface measurement, even in presence of emulsion or rag layers. Operating in process temperatures of -58 to 392°F and in pressures from -14.5 to 580 psi, Levelflex FMP55 offers measuring range up to 33 ft and provides 4-20 mA with HART output signal.

Endress+Hauser Announces Levelflex FMP55 Level Transmitter
Transmitter uses both capacitance and guided wave radar technologies to measure the level and the interface between two liquids.
Endress+Hauser announces the Levelflex FMP55 multiparameter level transmitter that 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. The transmitter will automatically switch between the technologies in order to provide a concise and reliable interface measurement, even in the presenence 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. The level sensor has a measuring range of up to 33 ft (10 m). The transmitter offers a 4-20mA with HART output signal plus an optional second 4-20 mA output
With its coated multiparameter probe, the FMP55 is ideal for interface measurement in the oil, & gas, and chemical industries. It can be used in process temperatures from -58 to 392F (-50 to 200C) and in pressures from -14.5 to 580 psi (-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.
The FMP55 is equipped with a HistoROM built into the main housing of the transmitter. 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. In the case of multiple units being set up at the same time with the same measurement parameters, the same HistoROM information can be transferred into a display that can be removed and installed in the next transmitter. This allows, allowing for the transfer of the set-up data, greatly reducing setup time during field commissioning.
Endress+Hauser offers three different setup methods for the FMP55. The first method is the use of the removable display. Second, the device can be fully commissioned via the three buttons on the display itself, using a menu-guided six-step quick setup. Third, Endress+Hauser's free FTD- based FieldCare software program allows for a very flexible method for setup ultilizing using a PC, and the software can be integrated into a complete lifecycle management system.
