GENERAL TERMS AND CONDITIONS

Measurement

 

 

Fahrenheit for low volume meters. When continuous

recorders are used, the arithmetic average of the

temperature recorded each day shall be used to compute

gas quantities.

 

E. The specific gravity of the gas delivered shall be

determined for any one Day by the use of instantaneous

specific gravity measurements applied to metering

instruments, shall be by the use of a continuously

recording gravitometer, or by approved methods with

such reasonable frequency as is found expedient in

practice. The method of test used for the

determination of specific gravity, in the absence of

continuous recording or instantaneous devices, shall

be by the use of an approved gravity instrument or

fractional analysis.

 

F. The deviation of gas from Ideal Gas Laws for orifice

meters shall be calculated according to the

recommendations of the American Gas Association

("A.G.A.") Measurement Committee Report No. 3,

entitled "Orifice Metering of Natural Gas," August,

1985, as may be amended or modified from time to time,

or by other mutually agreed upon methods. Turbine and

displacement meters shall be calculated according to

A.G.A. Report No. 7, 1981, as may be amended or

modified from time to time, or by other mutually

agreed upon methods.

 

G. The Total Heating Value shall be determined by

calculations from fractional analysis, or by methods

outlined in A.G.A. Measurement Committee Report No. 5,

latest edition, or by other mutually agreed upon

methods.

 

H. The Dt delivered shall be calculated either by

multiplying the Mcf delivered by the Total Heating

Value, and dividing the result by 1,000; or by

multiplying the pounds mass delivered by the Btu per

pound mass, and dividing the result by 1,000,000.
