Wet Gas Over-reading Characteristic Research of Inside and Outside Tube Differential Pressure Flowmeter

This paper designs a new type of the inside and outside tube differential pressure flowmeter based on the traditional flowmeters. Its structure is introduced and its theoretical formula is induced. For the online measurement of wet gas, this paper has done a lot of simulate experiments on the standard experimental platform. Applying origin drawing tools, it has drawn the relationship curves between influence parameters and over-reading specific value. And then, it analyzed the influence of different characteristic parameters. Finally, proceeding from the basis of over-reading theories, it has explained the internal reasons for these phenomenon.
