Diagnostic Action Comments
24 Pressure calculation Measurement of Process Pressure has failed.
This could be due to errors in attached cabling or
measurement equipment, defect sensor fron‐
tend electronics or configuration errors on chan‐
nels 3, 4, 5 or 6. Investigate DSL error codes to
determine precise root cause and required ac‐
tions. For processes with a constant pressure,
the pressure can alternatively be based on a
fixed user specified value.
25 Viscosity calculation Measurement of Process Viscosity has failed.
This could be due to errors in attached cabling or
measurement equipment, defect sensor fron‐
tend electronics or configuration errors on chan‐
nels 3, 4, 5 or 6. Investigate DSL error codes to
determine precise root cause and required ac‐
tions. For processes with a constant viscosity,
the viscosity can alternatively be based on a
fixed user specified value.
26 Sensor temp. comp. The clamp-on sensor temperature compensa‐
tion has failed, because measurement of tem‐
perature failed. This could be due to errors in
attached cabling or measurement equipment,
defect sensor frontend electronics or configura‐
tion errors on channels 3, 4, 5 or 6. Investigate
DSL error codes to determine precise root
cause and required actions. For processes with
a constant temperature, the sensor temperature
compensation can alternatively be based on a
fixed user specified process temperature.
27 Scraper pig detected Scraper pig detected. The ultrasonic signal was
temporarily interrupted when the scraper pig
passed through the sensor measurement sec‐
tion.
Only hydrocarbon
28 Configuration 1 An invalid configuration was detected. Investi‐
gate detailed diagnostics to determine precise
root cause. Investigate DSL error codes to de‐
termine which settings are invalid. The setup
parameters must be changed via the local dis‐
play menu or via an external configuration tool.
32 Auxiliary input The auxiliary measurement on CH5 or CH6 has
failed. This could be due to errors in attached
cabling or measurement equipment, defect sen‐
sor frontend electronics or configuration errors
on channels 3, 4, 5 or 6. Investigate DSL error
codes to determine which settings are invalid.
34 Invalid flow meas. Signal was lost on 1 or more paths causing the
measurement to stop or become untrustworthy.
Check if device is configured properly, Investi‐
gate DSL error codes to determine precise root
cause.
