✦ Synopsis

The primary element of the Coriolis #owmeter is a measuring tube conveying #uid. While the tube in the classical meter undergoes a beam-type vibration, the shell-type tube vibrates in the second circumferential mode. This paper analyzes theoretical characteristics of the straight-tube shell-type Coriolis meter. A mathematical model founded on the theory of FluK gge thin shell and linearized potential #ow was used. The results show the similarity between measuring principles in the shell-type and the beam-type meter. Finally, we carried out a comparison with the straight-tube beam-type meter, based on the condition that both meters have the same pressure loss. It was found that the shell-type meter has a higher working frequency and a larger phase shift due to #ow.

In this paper a fuller and clearer derivation of the weight vector theory of Coriolis mass flowmeters is given indicating its potential for the prediction of velocity profile effects in both the traditional kind of meter (vibrating tube) and the compact kind (vibrating element inside a duct).
