GENERAL TERMS AND CONDITIONS
17. MEASUREMENT AND MEASURING EQUIPMENT (Cont'd)
(f) For gas received or delivered hereunder, the heating value of the
gas in BTU's per cubic foot shall be determined by an on-line
chromatograph, recording calorimeter, or other method as may be
mutually agreed upon. Continuous gas samplers and spot samples
may also be used to obtain gas for analysis. The arithmetic
average of the hourly heating value determined during periods of
flow each day by an on-line chromatograph or recording
calorimeter will be the heating value of the gas during such day.
(g) The supercompressibility of the gas shall be determined in
accordance with the recommendations prescribed in A.G.A.
Transmission Measurement Committee Report No. 8, as amended,
titled Compressibility and Supercompressibility for Natural Gas
and Other Hydrocarbon Gases.
Any meter or meters installed by any party shall be installed at or
near each point of receipt or delivery. Such meters shall be of
industry standard type designed to measure the gas at the receipt or
WNG and Shippers shall test their respective chart recorders at
mutually agreed upon intervals; provided, however, that neither shall
be required to perform such test more than once in a thirty-day
period. At any such test the other may have a representative present
if it so desires. Shippers hereunder shall also have the right to
inspect WNG's meter settings at the receipt and delivery points in the
presence of representatives of WNG, request tests of WNG's chart
recorders and be present at such tests; provided, however, that WNG
shall not be required to conduct such tests more than once each month.
Shippers hereunder shall not alter or in any manner disturb,
manipulate or tamper with any of WNG's equipment.
At meters where any party other than WNG is responsible for changing
meter charts, such charts shall be received by WNG no later than 48
hours following the day they are changed.
