Pulsation created by compressors, flow control valves, regulators and some piping configurations are known to cause significant errors in gas measurement. In recent years the Pipeline-and Compressor Research Council (peRC) now know as (GMRC) Gas Machinery Research Council, a subsidiary of the Southern Gas Association, commissioned and funded various pulsation research projects at Southwest Research Institute (SWRI) in San Antonio, Texas. This research culminated in the publication of several technical papers, including the April 1987 peRC report 10.87-3 titled Pulsation and Transientinduced Errors at Orifice Meter Installations and a report, An Assessment of Technology for Correcting Pulsation Induced Orifice Flow Measuremenf dated November 1991.
