The size of the station and the number of compressors vary, based on the diameter of the pipe and the volume of gas to be moved. Typ- ical pressure levels for major transmis- sion systems are in the range of 5000 to 9000 kPa. Metering stations Metering stations are placed periodical- ly along natural gas pipelines. These sta- tions allow pipeline companies to mon- itor and manage the natural gas in their pipes. Essentially, these metering sta- tions measure the flow of gas along the pipeline, and allow to 'track' natural gas on its way to the end-user. Natural Gas Transmission from Wellhead to End User 3
