This paper presents laboratory and field test data for orifice and turbine meters in wet gas flow measurement. Laboratory testing has revealed that orifice meter measurement of natural gas with only small amounts of entrained liquid will have large errors. The data also indicates that commonly used correlations for two phase orifice metering are unacceptable for the low liquid loading at mass ratio below 2%. Controlled laboratory turbine meter tests using an air-water system at moderate pressure have shown that turbine meters are more accurate than orifice meters in a wet gas flow. Field data on orifice meter and turbine meter performance are also presented and results are compared to laboratory tests. The comparison indicates that the field performance of orifice meters have higher metering errors than laboratory results. The possible causes of the discrepancy are discussed. The authors concluded that the two most commonly used natural gas meters contributed higher measurement errors for long-term wet gas service.
