2. Measurement


2.1 Unit of Measurement and Metering Base - The volumetric measurement

base shall be 1 cubic foot of Gas at a pressure base of 14.73

pounds per square inch absolute, at a temperature base of 60

degrees Fahrenheit, and without adjustment for water vapor.


The cutoff for closing measurement is five Business Days after the

business Month (NAESB WGQ Standard 2.3.7). Measurement data that

is missing or late at the cutoff is to be estimated pursuant to

NAESB WGQ Standard 2.3.13. For treatment of measurement prior

period adjustments, treat the adjustment by taking it back to the

production Month. A meter adjustment becomes a prior period

adjustment after the fifth Business Day following the business

Month (NAESB WGQ Standard 2.3.11). For reporting measurement prior

period adjustments, report it with the restated line item with the

new total quantity for the Day and Month (NAESB WGQ Standard



2.2 Atmospheric Pressure. For the purpose of measurement, calculation

and meter calibration, the average absolute atmospheric

(barometric) pressure shall be based on the actual altitude of each

point of measurement irrespective of variations in natural

atmospheric pressure from time to time.


2.3 Temperature. The temperature of the Gas shall be determined at the

points of measurement by means of a properly installed temperature

transmitter of standard manufacture determined by Transporter in

exercise of its reasonable judgment to be installed in accordance

with the recommendations contained in API 14.3 and 21.1 First

Edition (Orifice Metering of Natural Gas). In the event electronic

computer measurement is used, average daily temperature will be

computed as a running average of data determined during each

computer scan.
