GENERAL TERMS AND CONDITIONS

 

 

3. MEASUREMENT

 

3.1 Unit of Measure

 

The unit of measure for gas transported by Transporter shall be a

dekatherm. Dekatherms delivered or received shall be determined

by multiplying the Mcf by a fraction, the numerator of which is

the Btu per cubic foot of gas and denominator of which is 1,000.

 

3.2 Unit of Volume

 

The unit of volume shall be one cubic foot of gas at a

temperature of 60 degrees Fahrenheit and an absolute pressure of

14.73 pounds per square inch.

 

3.3 Atmospheric Pressure

 

The average absolute atmospheric pressure shall be assumed to be

14.4 pounds to the square inch, irrespective of actual elevation

or location above sea level of the delivery or receipt points or

variations in such actual atmospheric pressure from time to time.

 

3.4 Temperature of Gas

 

The temperature of the gas flowing through the meters, when

necessary for computing gas quantities, shall be determined by

the use of a recording thermometer or other temperature measuring

device. The arithmetic average of the temperature recorded each

24-hour day, or so much of the 24 hours as gas has been flowing,

shall be used in computing gas quantities or instantaneous

temperature measurements may be applied to metering instruments

to provide the quantity computation. However, in case of any

small volume transaction, the installation of a thermometer may

be omitted at the election of Transporter and in such case the

temperature of the gas for the purpose of measurement shall be

assumed to be 50 degrees Fahrenheit.
