A wet gas flow facility has been operational at the CEESI Colorado location since 1999. The flowing fluids are gas and liquid phase mixtures of natural gas components. For most of the testing the gas phase has been "pipeline grade" natural gas and the liquid has been pure decane. The facility operates over a pressure range from 1.4 to 8.3 MPa (200 to 1200 psi). The dry gas velocity ranges up to 27 m/s (90 ft/s) in a 100 mm (4 in) pipe and the liquid flowrate ranges up to 164 kg/min (360 lb/min). This paper describes the components that contribute uncertainty to wet gas measurements.
