4. MEASUREMENTS

(a) Measurement Unit

The unit of the natural gas deliverable shall be a Dekatherm (one dt) of gas on the

measurement basis hereinafter set forth.

(b) Quantity and Heating Value

The quantity and the Heating Value of the natural gas delivered by Seller to or for

the account of Buyer or delivered by Buyer or Buyer's Supplier to Seller for

redelivery shall be determined as follows:

(i) The unit of volume for the purpose of measurement shall be one (1) cubic foot

of gas at a temperature of 60 degrees Fahrenheit and at an absolute pressure of

fourteen and seventy-three hundredths (14.73) pounds per square inch.

(ii) The unit of weight for the purpose of measurement shall be one (1) pound mass

of gas.

(iii) The average absolute atmospheric pressure shall be assumed to be 14.7 pounds

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.
