4. MEASUREMENTS

 

4.1 Metering: The gas shall be metered by one or more orifice or

displacement type meters, at the discretion of Crossroads. When

orifice meters are used, they shall he installed and maintained,

and volumes shall be measured in accordance with the methods

prescribed in "Orifice Metering of Natural Gas," Gas Measurement

Committee Report No. 3 of the American Gas Association, including

the Appendix thereto, as published September 1959, or any

subsequent revision thereof acceptable to both parties. When

displacement meters are used, the number of Mcf delivered

hereunder shall be computed by including factors for pressure,

temperature and deviation from Boyle's law.

 

4.2 Deviation from Ideal Gas Laws: Correction shall be made for

deviation of the gas from Boyle's Law at the pressure and

temperature at which the gas is metered. To determine the factors

for such correction, a quantitative analysis of the gas shall be

agreed upon by both parties or by computations made in

accordance with Gas Measurement Committee Report No. 3 of the

American Gas Association and any modifications and amendments

thereof applied in a practical manner.

 

4.3 Specific Gravity: The specific gravity of gas flowing through the

orifice meters shall be determined by means of a recording

gravitometer located at the delivering party's measuring station

or at any other point on said party's system where there will be

no commingling thereafter of gas with that delivered to the

receiving party, and the arithmetic average specific gravity each

day at such point shall be used in computing deliveries of gas

during the day at such points. Where displacement meters are

installed and where the quantities of gas metered will not be

materially affected by doing so, the specific gravity of the gas

for any day may be determined by any other recognized method

which may be practicable in the circumstances.

 

4.4 Flowing Temperatures: The flowing temperature of the gas being

metered shall be determined by means of a recording thermometer

of a type acceptable to both parties, installed and maintained in

accordance with the specifications set forth in said Gas

Measurement Committee Report No. 3. The arithmetical average of

readings each day for time that gas is flowing shall be deemed the

gas temperature and used in computing the volumes of gas metered

during such day.

 

4.5 Measurement: The Unit of Measurement for gas delivered or

redelivered hereunder shall be one thousand (1,000) cubic feet

(Mcf) of gas at a base temperature of sixty degrees (60ø)

Fahrenheit and at a base pressure of fourteen and seventy-three

hundredths pounds per square inch absolute (14.73 p.s.i.a).
