912 Inhomogeneous Fluid 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.
