* Faux and Fw are not AGA factors. Faux is a user set multiplier to compensate for liquids in the gas stream, defaults to
Fw is a factor which compensates for water vapor in the gas stream and its effect on volume measurements.

5.7.5 Super Compressibility Calculation (Fpv)
When the flow computer is powered up initially, the calculation method must be set. You have the option of changing the formula
method to any of several other choices, (see Table 10). Once the calculation type has been determined, you may toggle the
specific parameters may be toggled on or off depending upon whether using a fixed or live analysis data.
IMPORTANT NOTE: Calculation types, and many of the factors involved with setting up the calculations, are
usually dictated by the sales contract or by company policy.
