Abstract

In this paper a new sing-around type flow meter is proposed. Although sing-around type flow meters encounter problems when the flow is not stable, the proposed measurement method is approximately two times more accurate than current ultrasonic sing-around type flow-meters. The device comprises two ultrasonic-based flow-sensitive oscillators, one is installed upstream and another is installed downstream with respect to the flow direction. Unlike existing method, the upstream and downstream oscillators "synchronous-sly" start generating signals for each sampling cycle. The accuracy of the proposed method was compared with the existing method numerically, and its effectiveness was demonstrated with quantitative results.
