TROUBLESHOOTING
6.3
Checking the measuring mode setting of the pressure transmitter
▸
Go to menu item “Live Values/run”.
The pressure transmitter does not yet measure the pressure
●
The “Meter Pressure” value for the absolute pressure is “1”.
●
The “Meter Pressure” value for the over pressure is “0”.
The set measuring mode of the transmitter has to be changed if this is not the case.
Pressure transmitter already measuring
If the values of “Meter pressure” for absolute pressure as well as for overpressure are
negative and the error message “Compressibility calculation error” is displayed, the set
measuring mode of the transmitter must be changed.
Changing the transmitter measuring mode
1
Go to menu item “Configuration/Run/Pressure”.
2
Change the value for “Meter pressure input units” to “absolute” or “gauge”, depending
on the transmitter configuration. If anything is unclear, check the transmitter
configuration.
Note: The reference value of ambient pressure is 1.01325 bar (a).
6.4
Verifying the analog temperature transmitter
If the analog temperature transmitter sends incorrect temperature values or error
messages, check the scaling set on the transmitter.
Adjusting the scale on the Flow-X flow computer to the transmitter working range:
1
Go to menu item “IO/Configuration/Analog inputs”.
2
Set the value for “Analog input 2 full scale” to the maximum display value of the
temperature transmitter.
3
Set the value for “Analog input 2 zero scale” to the minimum display value of the
temperature transmitter.
Observe the following: Minor deviations are possible.
