Abstract: At the 2002 North Sea Flow Measurement Workshop (NSFMW) NEL and McCrometer jointly presented the results and analysis of the UKs Department of Trade and Industry (DTI) funded V-Cone meter wet gas flow tests on the NEL Wet Gas Loop. Two 6 beta ratios (0.55 and 0.75) were tested and for each meter the parameters influencing the differential pressure reading with wet gas flows were identified and found to be similar to other Differential Pressure (DP) meters. Correlations were then offered that would correct for the V-Cone meters liquid induced error in the gas flowrate prediction for a known liquid flowrate or liquid to gas flowrate ratio. This paper briefly summarises the V-Cone meter technology and then discusses the results of repeat wet gas flow tests at NEL in May 2003 (at nominally 15 and 60 Bar) for the 0.75 beta ratio V-Cone meter, to show the repeatability of the meter with wet gas flows and the reliability of the previously published wet gas flow correlation within the NEL parameter range. This paper then discusses wet gas flow testing done on a 4, 0.75 beta ratio V-Cone meter at CEESI in October 2002 across a different parameter range to that of NEL and compares the 0.75 beta ratio data sets at the two test facilities. The V-Cone meters 0.75 beta ratio correlation is then applied to the independent CEESI wet gas flow data set to investigate the applicability of the NEL data based correlation out with the NEL test range. With the correlations applicability shown, a discussion on the industrial advantages of a proposed Tracerflow and V-Cone meter combination is given. This is followed with new data showing the 0.75 beta ratio V-Cone meters performance at greater Lockhart-Martinelli parameters than previously tested (up to 0.5). A new correlation is discussed for this expanded range and the results of applying this new correlation to the NEL data set are presented. Finally, a rare field test showing the performance of a wafer cone meter with wet gas flow is discussed.
