Field of application

Levelflex FMP51 for level measurement even under extreme process conditions like
high temperature and high pressure in the process industry. FMP51 offers maximum reliability even in case of moved surface and foam or when numerous tank baffles interfere with the measurement. Levelflex FMP51 is used for continuous level measurement of liquids, pastes and slurries but also for interface measurement. The measurement is not affected by changing media, temperature changes, gas blankets or vapors.

Version with rod, rope or coax probe.

Process connections: Threads or flange
Temperature: -50 to +200°C (-58 to +392°F)
Pressure: -1 to +40bar (-14.5 to +580psi)
Maximum measuring range: Rod 10m (33ft), rope 45m (148ft), coax 6m (20ft)
Accuracy: ±2mm (0.08")
International explosion protection certificates, overfill prevention WHG, SIL, marine approval, 5-point linearity protocol
