Characteristic analysis of non-uniform mixed liquid density measurement based on Coriolis mass flowmeter

Builds a cantilever beam model with concentrated added mass on its end, analyses the relation between concentrated mass and vibration frequency of the cantilever beam. Assuming the mass flowmeter with mixed fluid in its flow tube, obtains the relation of measured density value and concentrated mass distribution. The simulation and experiment has proved the validity of the analysis. The paper lays the foundation of improving the non-uniform mixed liquid density measurement accuracy.
