This Technical Report is an advisory State of the Art document for wet gas flow metering applications as understood in 2005. It is based on available wet gas flow metering research papers, commercial literature and practical experiences from the oil and gas industry up unto the end of 2005. Topics included in this technical report: o Definition of terms o The significance of two-phase flow patterns to wet gas meter applications o Practical industrial problems that occur when applying the wet gas flow metering technologies o Uncertainty associated with wet gas flow metering o A comprehensive technical paper reference list. o The derivations and limitations of the published wet gas flow meter correlations
