The Levelflex FMP55 is a premium device with a coated multiparameter probe for interface measurement in the oil & gas, chemical and power industries. This device is designed for safe and reliable measurement both for the interface layer and the overall level by a redundant measuring system. The Levelflex FMP55 is factory precalibrated and features a menu-guided operating concept in national languages for intuitive operation and easy integration into control or asset management systems. It also comes with advanced diagnostics and approvals for various hazardous areas.

Depending on the interface, failure information is displayed as follows:
• Current output (for HART devices)
– Failsafe mode selectable (in accordance with NAMUR Recommendation NE 43):
Minimum alarm (for 2-wire units): 3.6 mA
Minimum alarm (for 4-wire units): 2.4 mA
Maximum alarm (= factory setting): 22 mA
– Failsafe mode with user-selectable value: 3.59 to 22.5 mA
• Local display
– Status signal (in accordance with NAMUR Recommendation NE 107)
– Plain text display
• Operating tool via digital communication (HART, PROFIBUS PA) or service interface (CDI)
– Status signal (in accordance with NAMUR Recommendation NE 107)
– Plain text display
The linearization function of the device allows the conversion of the measured value into any unit of length or volume. Linearization tables for calculating the volume in cylindrical tanks are pre-programmed. Other tables of up to 32 value pairs can be entered manually or semi-automatically.
All circuits for the outputs are galvanically isolated from each other.
