Research on a New Type Coriolis Mass Flowmeter Using Two Material

The Coriolis mass flowmeter has high precision,and its applicable range is very extensive. A new kind of Coriolos mass flowmeter tube is presented,which has a thinner wall in the symmetrical part along the center of the tube. A stronger second order Coriolis vibration can be detected using the new tube, so the system detecting sensitivity is greatly improved. The theory analysis and laboratory experiments have confirmed that. The reliability of this new structure and related making technology are researching.
