The profile factor represents the path velocity ratios
of inner to outer paths. A change of the profile value
may be caused by contamination, blockages or
deposits in the line that change the shape of the flow
profile.

The symmetry represents the path velocity ratios of
upper to lower paths. A change of the symmetry
value may be caused by contamination, blockages or
deposits in the line that change the symmetry of the
flow profile.

Theoretical
SOS deviation
0.3%
Optionally, a theoretical SOS calculated for the
current gas composition, temperature and pressure
can be written to the meter (e.g. from a flow
computer). If the current measured SOS deviates
from the theoretical SOS, a user warning is
generated.
Off
High gas velocity VOG limit 45 m/s
If the current Avg. Velocity of Gas exceeds the value
"VOG limit", a User Warning is generated.

1
User Warnings must be activated to become effective on the warning output.
2
These User Warning limits are only monitored, as long as certain preconditions are met. The VOG must be above the value set in "Min. VOG for warnings"
and the SOS must be relatively stable (change in %/s must be below the value set in "SOS profile rising").
3
The default value for these warning parameters can only be applied for a fully developed and symmetrical flow profile e.g. with a flow conditioner. The
values should be adapted to the specific application
