Abstract: Arkla Energy Resources developed and currently uses a mobile gas tuibine meter proving system on 3 thru 12 gas turbine meters at station sites under actual operating conditions. It combines technology from liquid turbine meter provers with new ideas that specifically apply to gas measurement. The prover also contains a gas chronatograph vich is used in actual mass flow coirpitations. This system has several advantages over earlier methods of proving gas turbine meters. Arkla previously proved its larger turiaine meters, capable of 60,000 ACFH, with a Roots transfer prover capable of only 10,000 ACFH. This meant that the provings were at or near increments on the proving curve where the K-factor might be in error for the turbine meters normal flow rate. With the sonic nozzle prover Arkla can now prove a turbine meter at the rate it is actually flowing. It is a fact that a turbine meter proven at 0 PSIG and then put into pressure service will exhibit a K-factor shift in the positive direction. Without sending the meter back to the manufacturer, this shift cannot be accounted for. The sonic nozzle prover calibrates turbine meters under actual operating pressmres, or densities, in lieu of atmospheric pressures, and it calibrates under actual operating temperatures.
