An on-line gas chromatograph and flow computer (▇▇▇▇▇▇ or Owner approved equal) shall be provided in the main gas line for measuring plant gas flow, heating value (Btu/Scf), relative density (specific gravity), and compressibility of the fuel gas. The chromatograph shall employ thermal conductivity detection with an accuracy of 0.1% over an operating range of 0oF to 130oF. The data shall be transmitted to a gas computer (provided by the Contractor) and then to the PCS for gas flow and equipment performance calculations. The Contractor shall incorporate reference conditions common to the gas suppliers. The orifice metering run shall meet the straight length requirements of ISO- -------------------------------------------------------------------------------- EPC - Exhibit B -------------------- TENASKA GEORGIA GENERATION PROJECT Page 130 of 132 -------------------------------------------------------------------------------- 5167 and the manufacturing and installation requirements of ASME MFC-3M-1989.
