7. MEASUREMENT & MEASUREMENT EQUIPMENT

 

7.1 Determination of Quantity

 

The quantity of gas received and delivered by Pipeline for Customer's

account hereunder shall be measured according to Boyle's and Charles' Laws for

the measurement of gas under varying pressures and temperatures with deviations

therefrom as provided in paragraph (I) below and shall be determined as follows:

 

(A) The unit of measurement for the purpose of service under any of

Pipeline's rate schedules shall be one (1) dekatherm (Dth),

consisting of one million (1,000,000) British Thermal Units. The

number of dekatherms delivered shall be determined by multiplying

the number of cubic feet of gas received or delivered, measured on

the measurement basis hereinafter specified, by the total heating

value of such gas, in British Thermal Units per cubic foot, as

defined in Section 1 of the General Terms and Conditions, and by

dividing the product by 1 million (1,000,000).

 

(B) The unit of quantity for the purpose of measurement shall be

1 cubic foot of gas at a temperature of 60o Fahrenheit and at an

absolute pressure of 14.73 pounds per square inch.

 

(C) The unit of weight for the purpose of measurement shall be one (1)

pound mass of gas.

 

(D) The average absolute atmospheric pressure shall be assumed to be

14.7 pounds per square inch.

 

(E) The temperature of the gas passing through the meters shall be

determined by the use of electronic transducers, recording

thermometer or other temperature measuring devices. The

arithmetic average of the temperature recorded each 24-hour day

shall be used in computing gas quantities or continuous

instantaneous temperature measurements as may be applied to

metering instruments to provide the quantity computation.

 

(F) The specific gravity of the gas flowing through the meters shall

be determined by gas chromatographic analysis, continuous

recording gravitometer, or continuous or spot sampling methods,

unless otherwise mutually agreed upon by Customer and Pipeline.

The arithmetic average of the specific gravity recorded during

each 24-hour day shall be used in computing gas quantities or

continuous instantaneous specific gravity measurements may be

applied to metering instruments to provide the quantity

computation.
