The volume and the total heating value of the gas delivered
to Transporter at the Receipt Point(s) and made available to or
on behalf of Shipper at the Delivery Point(s) shall be determined
10.1 Unit of Measurement. The unit of gas, for the
purpose of measurement, shall be one (1) Mcf.
10.2 Heating Value Per Cubic Foot. The total heating value
of the gas per cubic foot shall be determined for any month by
chromatographic analysis of a sample of gas collected daily
during the month by taking the weighted average of the heating
values as recorded each day by a calorimeter or as determined
by, or any other method mutually agreed upon by Shipper and
10.3 Determination of Dekatherms Delivered. The dekatherms
delivered shall be determined by multiplying the Mcf delivered by
the ratio of the Btu per cubic foot delivered to 1,000. For
purposes of this determination, the specific gravity and heating
value shall be determined at approximately the same time.
10.4 Determination of Temperature. The temperature of the
gas passing through each meter shall be determined for any day by
the continuous use of a temperature recording device so installed
that it may properly record the temperature of the gas flowing
through each meter. The arithmetical average of the temperature
recorded each day shall be used in computing gas quantities.
10.5 Specific Gravity. The specific gravity of the gas
shall be determined by calculations based on chromatographic
analysis and shall be checked at least once each month, or any
other method mutually agreed upon by Shipper and Transporter.
10.6 Deviation From Boyle's Law. The deviation of the
natural gas from Boyle's Law shall be determined by the use of
the table of formulas published by the American Gas Association
Par Research Project NX-19 corrected for carbon dioxide and
nitrogen, or any superseding applicable tables
