GENERAL TERMS AND CONDITIONS

(continued)

 

5. MEASUREMENT (continued)

 

(c) The static pressure of the gas passing through the meters shall be determined by

the use of electronic measurement equipment or by the use of another pressure

recording device. The instantaneous static pressure measurements from the

electronic measurement equipment or the arithmetic average of the temperature

recorded each Day shall be used in computing gas volumes.

 

(d) The temperature of the gas passing through the meters shall be determined by the

use of electronic measurement equipment or other temperature recording device.

The instantaneous temperature measurements from the electronic measurement

equipment or the arithmetic average of the temperature recorded each Day shall be

used in computing gas volumes.

 

(e) The specific gravity of the gas flowing through the meters, when necessary for

computing gas volumes, shall be measured by methods Algonquin deems to be in

accordance with accepted industry practice, such as, but not limited to, recording

gravitometer(s) or gas chromatograph(s) located at appropriate point(s). The

arithmetic average of the specific gravity recorded each Day or other periodic

measurements within a shorter time frame as Algonquin shall select may be applied

to metering instruments to provide the volume computation.

 

(f) The volume of gas shall be determined in accordance with, but not limited to, the

published recommendations of the American Gas Association and the American

National Standards Institute as Algonquin deems to be in accordance with accepted

industry practice.

 

(g) The deviation of the gas from Boyle's and Charles's Law shall be determined in

accordance with, but not limited to, the published recommendations of the American

Gas Association and the American National Standards Institute as Algonquin deems
