Abstract

A new design concept for improving the sensitivity of a Coriolis flowmeter is proposed. The differences between the developed flowmeter and current commercial products lie in adoption of acceleration sensors and reinforcement frames. These features impart an interesting characteristic: sensitivity improves with increasing drive frequency. A flow tube has been fabricated on the basis of the new design concept, and subjected to basic experiments in order to confirm the characteristics of the measurement system. Although some problems still remain, the characteristics have been partially confirmed.
