GENERAL TERMS AND CONDITIONS

(Continued)

(iii) The flowing temperature of the gas shall be determined for the purpose 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 by RTD's, thermocouples, thermometers, etc. and

shall be either (1) recorded using charts, digital recorders, etc., in which

case the temperature at which gas was measured for the period of such record

shall be the arithmetic average of the record during the period of time

during which gas was flowing; or (2) used for on-site flow computations in

electronic flow computers in which case the instantaneous measurement of

temperature will be used in such computations. Where no temperature measuring

device is installed, the temperature of the gas shall be assumed to be 60

degrees Fahrenheit.

(iv) A specific gravity correction shall be applied to measured volumes. The

specific gravity to be used for such correction shall be determined at an

appropriate location by a gravitometer, chromatograph, or other device of

standard manufacture and shall be either (1) recorded using charts, digital

recorders, etc., in which case an arithmetic average (to be determined during

the period of time during which flow was occurring at the location of the

specific gravity recorder) of such record shall be the specific gravity of

the gas being measured; or (2) used for flow computations in electronic flow

computers in which case the value of the specific gravity being measured will

be used as appropriate in such computations. If a specific gravity measuring

device is not installed or available at an appropriate location, then

specific gravity shall be determined by a mutually agreeable method.
