Often problems with unstable/wrong measurements occur due to insufficient/wrong earthing or
potential equalization. Please check this connection. If OK, the SITRANS F M MAGFLO

Converter check list
When checking SITRANS F M MAGFLO
installations for malfunction the easiest method to
check the signal converter is to replace it with another MAG 5000/6000 converter with a similar
power supply.
A replacement can easily be done as all settings are stored in and downloaded from the
SENSORPROM
unit - no extra settings need to be made.
If no spare converter is available - then check converter according to check table.
