Emerson has been selected to supply a Daniel Ultrasonic Custody Transfer flow measurement solution for the pipeline, ranked as one of the largest pipelines to be built in the world.
The 4,000km conduit will transport natural gas from the Tarim Basin in the northwest region of Xijiang to Shanghai, China's largest city.
PetroChina has completed a joint framework agreement with Shell, ExxonMobil, Gazprom, Hong Kong and China Gas for participation in the project.
"Emerson was selected because of its commitment to the China market and its tremendous fiscal gas measurement experience with Daniel solutions," said Chen Xiwu, vice president of the WEPP project.
"Transporting more than $4 billion of gas annually, we need to insure that our custody transfer measurement system is as accurate and reliable as possible. Emerson's Daniel flow measurement equipment will meet our needs."
The project will satisfy the increasing demand for cleaner energy in the wealthy Shanghai region, while boosting investment in the Xijiang area.
Emerson will supply 13 Daniel SeniorSonic ultrasonic custody transfer metering skids, including Danalyzer gas analyzer systems and control room based data collection and management systems. The metering skids will be installed and operational for the proposed 2004 initial delivery of gas to the Shanghai region.
