Possible Causes
The temperature value on the Meter Run is outside
the allowable limits for the selected measurement
algorithm.
The pressure value on the Meter Run is outside the
allowable limits for the selected measurement
algorithm.
The density value on the Meter Run s outside the
allowable limits for the selected measurement
algorithm.
Troubleshooting
Suggested Action
•
Check the temperature value from the
transmitter.
•
Check any override value in use.
•
Check whether the signal scaling for the
temperature transmitter is properly configured.
•
Check the pressure value from the transmitter.
•
Check any override value in use.
•
Check whether the signal scaling for the pressure
transmitter is properly configured.
•
Check the density value from the transmitter.
•
Check any override value in use.
•
Check whether the signal scaling and factory
entered coefficients for the density transmitter are
properly configured in the flow computer.
