3.6.5 Supercompressibility calculation (Fpv)

When the G4 EX is powered up, the calculation method needs to be set. The user
has the option of changing the formula method to any one of several other choices
(see Table 3–2). Once the calculation has been determined, the user may toggle
specific parameters on or off depending upon whether they would like to use fixed
or live analysis data.

4 Not an AGA factor. Fw is a factor which compensates for water vapor in the gas stream and its effect on volume
measurement.
5 Not an AGA factor. Faux is a user set multiplier to compensate for liquids in the gas stream. Defaults to 1.
6 Discharge Coefficient Type-only AGA-3 1992 and ISO-5167-1
7 NX19 GCN, NX19 GCNM, AGA-8 1992 Gross
8 Enter the Heating Value in Btu per SCF. Not used in volume calculations. Only used for calculating MMBTU for reports.
