Inhomogeneous
Fluid is inhomogeneous, e.g. gas or solid
content!
1. Check process conditions.
2. Increase system pressure.
In particular with out gassing fluids 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.
Warning

Inhomogeneous
Oscillation amplitude limit.
The fluid properties do not allow a precise
measurement.
Cause: Process fluid is very inhomogeneous (gas
or solid content)
1. Check process conditions
2. Increase supply

The event history includes entries for:
• Diagnostics events (
In addition to the operation time of its occurrence, each event is also assigned a symbol that indicates
whether the event has occurred or is ended:
