GENERAL TERMS AND CONDITIONS (Continued)

 

5. MEASUREMENT (Continued)

 

Committee Report No. 5, AGA Committee Report No. 7, or revisions

or amendments thereto. The absolute atmospheric pressure used for

volume calculations shall be the average atmospheric pressure

determined by calculations based on the actual elevation above sea

level of the meter at the place of measurement.

 

5.3 Unit of volume: The basic unit of volume for purposes of

measurement shall be one (1) cubic foot of gas as defined in

Subsection 1.5. However, the total energy transfer for purposes

of measurement shall be on a dekatherm (dkt) basis as defined in

Subsection 1.7.

 

5.4 Specific gravity: The specific gravity of the gas gathered,

transported and/or stored hereunder shall be determined by

Transporter at the point(s) of receipt and delivery or at point(s)

representative of such point(s), at necessary intervals, but at

least once each ninety (90) days unless otherwise mutually agreed

upon, by use of a gas analysis or an indicating gravitometer of

standard make, and the results of which shall be applied to the

volume determination during the subsequent test interval.

However, if at the option of Transporter a recording gravitometer

or gas chromatograph is installed, operated and maintained, the

arithmetical average or real time integration of the specific

gravity so measured while gas is flowing during each metering

interval shall be used to correct the volumes of gas transported

hereunder to the unit of volume specified in Subsection 5.3

hereof.

 

5.5 Carbon Dioxide and Nitrogen: The carbon dioxide and nitrogen

content of the gas gathered, transported and/or stored hereunder

shall be determined by Transporter at the point(s) of receipt and

delivery or at point(s) representative of such point(s), at

necessary intervals, but at least once each ninety (90) days

unless otherwise mutually agreed upon, by use of a gas analysis,

the results of which shall be applied to the volume determination

during the subsequent test interval. However, if at the option of

Transporter a gas chromatograph is installed, operated and

maintained, the real time integration of the carbon dioxide and

nitrogen so measured while gas is flowing during each metering

interval shall be used to correct the volumes of gas transported

hereunder to the unit of volume specified in Subsection 5.3

hereof.
