Possible causes Actions
Profile factor
1
A change of the symmetry value may be caused
by contamination, blockage or deposits in the
line that change the symmetry of the flow profile.
 Compare the current value with previous
measurements (e.g. Maintenance Report
from commissioning) and check whether the
User Warning limit is configured correctly
(
 pg. 149, 5.7.1).
 Create a Diagnosis Session according to
 pg. 198, 7.3 and contact your trained staff.

Theoretical
(SOS) deviation
A deviation of the measured Speed of Sound
(SOS) from the theoretical SOS may be caused
by:
– asynchronous determination of the
measured and the theoretical SOS due to
fluctuations in gas composition and analysis
time lag,
– malfunction of the pressure measurement,
– malfunction of the temperature
measurement,
– malfunction of the gas composition
measurement,
– malfunction of the meter,
– or deposits on the transducer(s) or meter
body which change the path length.
 Check the theoretical SOS for plausibility
using the SOS calculator -> see Maintenance/
Routine Checks / Comparing theoretical and
measured Speed of Sound (SOS)
 Check the updating cycle between meter and
the device transmitting the theoretical SOS
 Check the pressure and the temperature
measurement for plausibility or errors
 Create a Diagnosis Session according to
 pg. 198, 7.3 and contact your trained staff.
High gas
velocity
The current average Velocity of Gas exceeds the
value "VOG limit".
 The VOG limit should be configured to suit
your application.
Low input
voltage (power
supply)
The power supply voltage is below the value
"Input voltage warning" and may indicate a
potential problem of the power supply (e.g. low
battery status of solar powered system).
 Check the power system

These User Warning limits are only monitored, as long as certain preconditions are met (  pg. 154, Table 22).
