AGA 8 Data Ranges

AGA 8 compressibility calculations can optionally take into account expanded data ranges. The field values received by the application are recognized within either the standard or expanded data ranges described below, depending on whether or not the Use AGA 8 expanded range property is configured for the device. The compressibility calculations generate corrected volume and energy values based on these ranges, and the resultant values are used in the data validation process.

AGA 8 Data Ranges

Standard and expanded data ranges for each data item that can be used in AGA 8 calculations are listed in the following tables, by calculation type.
