In order to better simulate the flowing condition of wet gas and develop laboratory studies based on differ-ent wet-gas flow measurement principles and methods,the flow laboratory of Tianjin University designed and built the wet gas experimental facility with adjustable and intermediate pressure. The designed pressure of the facility is 4,MPa,using the design of standard meter method and dual closed-loop. It includes an independent gas circulation loop,an independent liquid circulation loop and an experimental mixed pipeline. The experimental medium is air and water,and the highest working pressure is 1.6,MPa. The gas flow rate range is 3-1,000,m3/h,and the liquid flow rate range is 0.05-8.00,m3/h. The study includes the structure designing of the facility,the calculation of pressure loss,the selection of key equipment,the facility electrical control system designing and debugging,etc. Based on the uncertainty analysis of the facility,It is concluded that the facility’s gas measurement uncertainty is 1.00%and its liquid measurement uncertainty is 0.35%.
