The Flowmeter Calculation window allows you to view and edit the status of the selected flowmeter instrument. If this is a new tag that you just created in the Calculation module, the process data section of the window will be blank. Select the required Fluid State and the process data section will become available for data entry. Some process data properties may vary depending on the selected Fluid State.
To access this window, select and then select an instrument tag.
Fields that are mandatory for calculations appear with either cyan or yellow background highlighting, according to the following definitions:
-
A cyan background indicates that you must enter a value on the process data sheet.
-
A yellow background indicates that you may enter a value on the process data sheet, or you can leave it blank and enter a value for that field later on the calculation sheet.
To activate the highlighting option, select Options > Highlight Process Data.
