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.
