(vi) 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 Company. 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.

 

(vii) When orifice meters are used, the computation of

quantities of gas delivered shall be in accordance with

the recommendations as published by the American Gas

Association's Report No. 3, Revised - 1990, and the

ANSI/API 2530, First Edition, and any subsequent

amendments thereof as may be mutually agreed upon by

Customer and Company.

 

(viii)The total heating value shall be determined by gas

chromatographic analysis or by other methods mutually

agreed upon by Customer and Company. The arithmetic

average of the heating value recorded each 24-hour day

and as adjusted to conditions as specified in Section 1

of the General Terms and Conditions, or continuous

instantaneous heating value measurements, shall be used

for computations requiring energy characteristics.

 

(ix) The deviation of the gas delivered hereunder from Boyle's

and Charles' Laws shall be determined by gas chromatographic

analysis or by analytical methods mutually agreed upon by

Company and Customer. The amount of nitrogen and carbon

dioxide contained in the gas shall be determined, for the

purpose of determining the deviation factors, every three

(3) months or at such other intervals as is found expedient.

 

5. MEASUREMENT EQUIPMENT

 

(a) Measuring Facilities

 

Company will install, maintain and operate a measuring facility

properly equipped with standard orifice meters, flange

connections, orifice plates and other necessary measuring

equipment in compliance with AGA Report No. 3. At Company's

discretion, other standard type meters may be used provided

that such are suitable for the purpose by which the quantities

of gas received for liquefaction and vaporized for delivery shall

be measured and determined. Where orifice measurement equipment

is to be used, it shall utilize "Flange Tap Connections" and the

static pressure shall be measured at the down-stream flange tap

connection. Orifice meter chart recorders or electronic flow
