Levelflex FMP55: SensorFusion for Reliable Interface Measurement
Simultaneous overall level and liquid/liquid interface measurement—even where emulsion layers make the application difficult.
The Endress+Hauser Levelflex FMP55 is a multiparameter instrument designed for demanding interface applications in the oil and gas, chemical, petrochemical and power industries. Its SensorFusion concept combines guided radar and capacitance in one device, allowing the transmitter to measure both total level and the interface between two liquids.
WHY CHOOSE THE FMP55?
• Simultaneous measurement of overall level and liquid/liquid interface from one process connection.
• SensorFusion combines guided radar and capacitance for reliable results in challenging media.
• Rod, rope and coaxial probes support a wide range of vessel geometries.
• Factory pre-calibration and HistoROM simplify commissioning and device replacement.
• Heartbeat Technology supports verification and process monitoring.
TECHNICAL HIGHLIGHTS
Measuring principle: Guided radar plus capacitance (multiparameter SensorFusion)
Measured variables: Overall level and liquid/liquid interface
Accuracy: ±2 mm
Process temperature: −40 to +200 °C
Process pressure: Vacuum to 40 bar
Maximum range: Rod 4 m; rope 10 m; coaxial 6 m
Wetted materials: 316/316L, PTFE and PFA
Communication: 4–20 mA HART, PROFIBUS PA, FOUNDATION Fieldbus; optional Bluetooth/SmartBlue
TYPICAL APPLICATIONS
FMP55 is well suited to separators, storage tanks and process vessels containing two liquid phases. Typical duties include oil/water interface measurement, hydrocarbon separation, solvent or chemical phase monitoring, and condensate or utility systems where both interface and total level are important.
SPECIFY THE RIGHT CONFIGURATION
Probe type, measuring range, process connection, wetted materials, pressure/temperature rating, hazardous-area approval and communication protocol should be checked against the actual application. For a quotation, please provide the complete order code or nameplate photo together with vessel dimensions and information about both media.
