Original Sheet No. 518 Original Sheet No. 518 : Effective
pressure of 14.73 pounds per square inch absolute.
For the purposes of pricing hereunder, the dekatherm
equivalent of such unit of volume shall be determined
by multiplying each such unit of volume by the total
heating value per cubic foot of the Gas delivered
hereunder (adjusted to a common temperature and
pressure base) and by dividing the result by one
(b) The average absolute atmospheric (barometric) pressure
at the Point of Delivery/Receipt shall be assumed to
be equal to 14.4 pounds per square inch.
(c) The flowing temperature of the Gas shall be determined
by means of an instrument of standard manufacture
accepted in the industry for this purpose.
(d) The supercompressibility factor used in computing the
volume of Gas delivered through an orifice meter shall
be determined in a manner which yields results
consistent with the results produced by the procedures
presented in the American Gas Association Transmission
Measurement Committee Report No. 8 entitled
"Compressibility and Supercompressibility for Natural
Gas and Other Hydrocarbon Gases."
(e) The specific gravity of the Gas used in computing the
volume of Gas delivered through a meter shall be
determined by one of the following methods:
(i) At intervals of not more than six (6) Months, by
means of an instrument of standard manufacture
accepted in the industry for this purpose using
a sample of Gas from the Gas stream at the Point
of Receipt or Point of Delivery.
(ii) By means of an instrument of standard
manufacture accepted in the industry for this
purpose installed at a point to measure the
specific gravity of the Gas stream from which
Gas is being delivered at the Point of Receipt
or Point of Delivery.
