FMB51 Hydrostatic Level measurement Deltapilot

Field of application

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.

For level measurement.
