Wet gas meter is a meter for inline measurement of wet gas flow. The meter measures the water content in the wet gas steam and individual flow rate of hydrocarbons and water. Accurate measurement of wet gas flow including water and liquid detection is crucial for the operators of wet gas producing fields of many reasons such as well testing, improved reservoir management, production allocation, formation and corrosion. It is a total volume meter and it is use an accurate master meter is therefore restricted to total volume meters.
