Abstract:
When fluid f lows through a vibrating U-tube,Coriolis forces are generat ed in opposite directions in the straight limbs of the U-tube and the ef fect of Coriolis forces is t o caus e a tw is ting of the tube. T he twist ing is direct ly proport ional t o the product of f luid dens it y and velocit y, invers ely proportional t o the tw is ting st if fness of the syst em. In this paper , based on st at ic mechanics, the s ens it ivit y of a f low met er is analysed and calculated under the condit ion of omitting some f act ors such as the action of damping on the U-tube wall, and only cons idering the action of Coriolis forces on the U-tube, which provides the basis of design for sensor syst em and succeeding signal processing circuits .
