Development of multi-path ultrasonic flow meter based on embedded system

According to the research status of ultrasonic flow meter in china, a kind of multi-path ultrasonic flow meter for measuring a large flow amount of a fluid in a large diameter pipe based on the measurement principle of multi-path ultrasonic flow meter. The embedded technology is applied in the development. A design idea of multi-path ultrasonic flow meter based on embedded system is presented, and the method for realizing the design idea is explained in the paper. Moreover, the test result in lab is given, and the test result is proved the performance of the developed flow meter is good under the laboratory condition. The reasons that cause test result is analyzed in the paper.
