Abstract: Natural gas fl ow rate measurement errors at fi eld meter stations can result from the installation confi guration, the calibration of the meter at conditions other than the actual operating conditions, or the degradation of meter performance over time. The best method for eliminating these or other sources of error is with in-situ (on-site) calibration of the meter. That is, the measurement accuracy of the fi eld meter station should be verifi ed under actual operating conditions by comparing to a master meter or prover. Field provers have been developed for operation at high line pressures and fl ow rates. For purposes of this discussion, a high gas fl ow rate is any fl ow greater than 3,000 actual cubic feet per hour or (85 m3/h) at pressures to 1,440 psig (10 MPa).
