A novel d／p flowmeter is introduced． In accordance with the different flow characteristics under supercritical and subcritical flowing status the flowmeter provides functions from both sonic and subsonic Venturi tube and computer-based flowmeter． Thus the measuring range is extended and the problem of correcting the measuring deviation under varying operation status is realized．
