Abstract:
     Pushed by the fluid pressure difference, the volume cavity among rotor, casing and core column is rotated and the fluid is conveyed quantitatively from inlet to outlet to complete the flow measurement. The joint location between moving and static parts is cylinder and plane with high machining and assembly precision, and this results in less slip flow amount and high flowmeter precision. The single and multiple volume cavity scheme reduces the dynamic disequilibrium, raises the efficiency and reduces the noise and wear.
