Measurement Standards and Tests Clause Samples

Measurement Standards and Tests. The gas shall be measured and tests for quality of gas shall be governed by the following: (a) The volume shall be measured by multi-path ultrasonic meters installed and operated and computations made as prescribed in Transmission Measurement Committee Report No. 9 of the American Gas Association, as such report may be amended or revised from time to time. Turbine meters may be used for the measurement of low flow and, if used, will be installed and operated and computations made as prescribed in Transmission Measurement Committee Report No. 7 of the American Gas Association, as such report may be amended or revised from time to time. All installations shall include the use of flange connections and straightening vanes, or by other measuring methods as may be mutually agreed to by the Parties (approval of such methods shall not be unreasonably withheld). The design and construction of any such measurement facilities shall be in accordance with mutually agreeable specifications. (b) The unit of volume for purposes of measurement shall be one (1) cubic foot of gas at a temperature base of sixty degrees (60°) Fahrenheit and at a pressure base of fourteen and seventy-three hundredths (14.73) pounds per square inch absolute. The unit of energy shall be one (1) dekatherm. (c) Computation of volumes shall be made using an on line gas flow computer ("GFC"). Temperature, pressure and volumetric measurements shall be input to the GFC at least once per second. The computational method and averaging technique shall meet the minimum requirements of "Flow Measurement Using Electronic Metering Systems", Chapter 21 of the Manual of Petroleum Standards, published by the American Petroleum Institute. (d) Gas analysis shall be determined using an on line gas chromatograph. Gas Density and compressibility shall be determined by the methods described in American Gas Association Transmission Measurement Committee Report No. 8, "Compressibility Factors of Natural Gas and Other Related Hydrocarbon Gases", gross method, latest revision. (e) The total heating value of the gas shall be computed from the same on-line chromatographic analysis. (f) Either Party may, at its sole cost, perform special tests to determine sulphur, hydrogen sulfide, oxygen, carbon dioxide, and nitrogen content, which shall be made by approved standard methods in general use by the gas industry. (g) All measuring and testing equipment, housing devices and materials shall be of standard manufacture, and shall...
