Abstract: Natural gas ow rate measurement errors at eld meter stations can result from the installation conguration, 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 eld meter station should be veried under actual operating conditions by comparing to a master meter or prover. Comparisons of ow meters in the eld have been performed for nearly as long as ow meters have been in existence. For example, Figure 1 shows an orice meter being compared to three 60-A tin meters (a.k.a., diaphragm meters) in Rosedale, Kansas in 1921.1 Each tin meter had the ow capacity of 1,800 standard cubic feet per hour. In this particular test, a 1.6% difference in reading was discovered between the orice meter and the tin meters (so named because their housings were made of thin tinned sheet metal.
