  • Deltapilot FMB51 rod version
  • Deltapilot FMB51

Pressure sensor with the Contite measuring cell for hydrostatic level measurement

The Deltapilot FMB51 is a rod version with a fixed process connection. This device with the Contite measuring cell and is typically used in the environmental industry. It is made for level measurement in liquid and paste-like media in open or closed containers and is unaffected by possible foam formation. For use in SIL2 safety systems.
