摘要：

The primary element of the Coriolis flowmeter is a measuring tube conveying fluid. 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 Flugge thin shell and linearized potential flow 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 flow. (C) 1999 Academic Press.
