GENERAL TERMS AND CONDITIONS
5. MEASUREMENT & MEASUREMENT EQUIPMENT con't
(d) The average absolute atmospheric pressure shall be assumed
to be 14.4 psia.
(e) The flowing temperature of the Natural Gas shall be
determined for the purposes of measured volume correction.
Volume shall be corrected for each degree of variation in
the flowing temperature from 60 degrees Fahrenheit. The
flowing temperature will be measured continuously and, at
Transporter's option, shall be either (1) recorded using
recording devices of standard make, in which case the
temperature at which Natural Gas was measured for the period
of such record shall be the arithmetical average of the
record during the period of time the Natural Gas was
flowing, or (2) determined by using on-site flow
computations in electronic flow computers, in which case the
instantaneous measurement of temperature will be used in
computing Natural Gas quantities.
(f) The specific gravity of the Natural Gas flowing through the
meters shall be determined by Natural Gas chromatographic
analysis of composite samples, recording gravitometer, or
continuous sampling methods, unless otherwise mutually
agreed upon by Shipper and Transporter. The arithmetic
average of the specific gravity recorded during each Day
shall be used in computing Natural Gas quantities or other
periodic measurements within a shorter time frame or
instantaneous specific gravity measurements may be applied
to metering instruments to provide the quantity computation.
If a continuous specific gravity measuring device is not
installed or is not available at an appropriate location,
then specific gravity shall be determined monthly from a
continuous or composite sampling device or by a mutually
agreeable method.
