GENERAL TERMS AND CONDITIONS

(continued)

 

 

4.4 For measurement by turbine or orifice meters, the arithmetic average of gas temperatures

recorded during the periods of flow only shall be deemed the gas temperature for the purpose of

calculating transport quantities. However, when computing quantities of gas measured by

displacement type meters, the gas temperature shall be deemed to be the average monthly ambient

temperature corresponding to each calendar month as recorded and published as Local

Climatological Data by the U.S. Department of Commerce, Weather Bureau, for that weather

station nearest the actual point of receipt or delivery; or as may be otherwise mutually agreed

to by Operator and Transporter.

 

4.5 The specific gravity and total heating value of the gas to be measured shall be determined by

one of the following methods: (1) a spot gas sample analyzed on a gas chromatograph with the

frequency of the sampling being as agreed to by Operator and Transporter, (2) use of a

continuous, proportional to flow, gas sampler and the sample analyzed on a gas chromatograph,

(3) by the continuous use of an "on line" gas chromatograph, or (4) any other method agreed to

by Operator and Transporter. All chromatographic analysis are to be as per GPA 2172 using

factors from the latest edition of GPA 2145, as may be amended from time to time.
