Configure AGA8 parameters
Configure the properties necessary for the AGA8 calculations.
How the AGA8 calculations to be performed:
•
Internally by the meter - calculates the flow mass density, the flow compressibility and the
base compressibility.
•
Externally - calculations are done externally. The calculated values must then be written to
the meter using Daniel MeterLink™ or a flow computer.
AGA8 method
•
Gross Method 1
•
Gross Method 2
•
Detail - enter the amount of each of the 21 gas components as a percentage.
Gas composition
•
Fixed - use the fixed gas composition stored in the meter for all calculations
•
Live GC - use a gas composition collected by the meter from a gas chromatograph for all
calculations. This option is only available with a GC key or is enabled with the Continuous
Flow Analysis key.
