Inhomogeneous
Medium is inhomogeneous, e.g. gas or
solid content
1. Check process conditions.
2. Increase system pressure.
In particular with outgassing
media and/or increased gas
content, the following measures
are recommended to increase
system pressure:
• Install the instrument at the
outlet side of a pump.
• Install the instrument at the
lowest point of an ascending
pipeline.
• Install a flow restriction, e.g.
reducer or orifice plate,
downstream from the
instrument.

Inhomogeneous
Oscillation amplitude limit!
The medium properties do not allow a
precise measurement.
Cause: Process medium is very
inhomogeneous (gas or solid content)
1. Check process conditions.
2. Increase voltage.
3. Check main electronic module or
sensor.
