Setting the reference temperature
For the temperature value to be used in CTL calculation, you can use the temperature data from the
sensor, or you can configure external temperature compensation to use temperature data from an
external temperature device.
• To use temperature data from the sensor, no action is required.
• To configure external temperature compensation, see Section 2.8.
Setting the thermal expansion coefficient
If the CTL derivation method for the petroleum measurement table type is method 2, you need to set
the thermal expansion coefficient (TEC). To set a user-defined TEC, refer to the flowcharts in
Figure 4-5.
