【Abstract】 The mass flow-rate and fluid density can be on line measured directly by Coriolis Mass flow meter in the same time. This paper gives a differential equation of the sensor vibration and derives optimal design of the sensor. As the result of derivative vibration frequency for the dual U-type tubes determined the density of the fluid.更多还原
