Levelflex FMP54 for continuous level measurement in liquids under extreme conditions. The process connection with its ceramic-graphite seal safeguards high temperature and high pressure applications as they occur in steam boilers and toxic media like ammonia. The gas tight feedthrough guarantees additional safety. Only the gas phase compensation of the FMP54 gives reliable results in case of gas and steam phases. Reliable measurement in case of moving surface and foam or in changing medias.


  • Reliable measurement even for changing product and process conditions

  • HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics

  • Highest reliability due to new Multi-Echo Tracking evaluation

  • Hardware and software developed according to IEC 61508 up to SIL3

  • Seamless integration into control or asset management systems

  • Intuitive, menu-guided operation concept (on-site or via the control system) in national languages reduces costs for training, maintenance and operation

  • World's easiest proof test for SIL and WHG saves time and costs
