Application Scope
The Levelflex FMP54 provides continuous liquid level measurement in extreme conditions. Featuring a ceramic-graphite sealed process connection, it handles high-temperature and high-pressure environments like steam boilers and toxic substances such as ammonia. The gas-tight feedthrough ensures extra safety. Unique gas phase compensation delivers accurate readings in gas/steam environments. Performs reliably with turbulent surfaces, foam, or changing media.
Available with rod, rope, or coaxial probe configurations.
