V
= Volume of gas sample measured at the dry gas meter, dcf
m
Y = Dry gas meter calibration factor, dimensionless
P
= Barometric pressure at the testing site, in. Hg
bar
∆H
Average pressure differential across the orifice meter, in. H
=
Absolute average dry gas meter temperature, °R

Sample Calculation:
Using equation for Train 1:
V =
17.64 x
m(std)
27.830
V =
dscf
m(std)
Using equation for Train 2:
V =
17.64 x
m(std)
V =
26.690 dscf
m(std)
Using equation for ambient train:
V =
17.64 x
m(std)
V =
