During filling/
emptying or
measumement the
measured value
jumps sporadically
to a higher level
L00-FMR250xx-19-00-00-en-015
Signal is weakened (e.g.
by fluidisation of the
surface, extreme dust
formation) – the
interference echoes are
sometimes stronger.
Strong build-up, filling
stream in path of beam.

E641 (loss of echo)
L00-FMR250xx-19-00-00-en-018
Level echo is too weak.
Possible causes:
• fluidisation of the
surface
• extreme dust
formation
• angle of repose
