GENERAL TERMS AND CONDITIONS
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
