GENERAL TERMS AND CONDITIONS

 

 

5. MEASUREMENT AND MEASUREMENT EQUIPMENT (Cont'd.)

 

the actual location or elevation above sea level of

the Point of Receipt or Point of Delivery or of

variations in actual atmospheric pressure from time to

time.

 

(iii) The flowing temperature of the Gas shall be determined

by means of an instrument of standard manufacture

accepted in the industry for this purpose.

 

(iv) The supercompressibility factor used in computing the

volume of Gas delivered through an orifice meter shall

be determined in a manner consistent with the

procedure presented in the American Gas Association

Transmission Measurement Committee Report No. 8

entitled "Compressibility factors of Natural Gas and

Other Related Hydrocarbon Gases."

 

(v) The specific gravity of the Gas used in computing the

volume of Gas delivered through a meter shall be

determined 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.

 

(vi) The compressibility ratio factor "s" used in computing

the volume of Gas delivered through a turbine meter or

a positive deplacement meter shall be determined by

the equation s = (Fpv)2, in which "(Fpv)" is the

supercompressibility factor determined as described in

subparagraph (iv) of this subsection (b).

 

(vii) In determining the flowing temperature factor,

supercompressibility factor, and compressibility ratio

factor "s" for use in computing the volume of Gas

delivered through a meter, the flowing gas temperature

for only the period(s) of time that Gas was flowing

through the meter shall be used.
