Abstract

A multi-channel ultrasonic flowmeter was designed in this paper which is composed of supersonic transducer, electron circuit, flow rate indication and integral calculation system. Based on the concept of liner concentration of coal logs in pipeline and characteristics of Doppler frequency drift of coal particles and coal logs moved in pipeline, the measuring method of supersonic wave and the transportation principle of coal slurry-coal log pipeline were discussed and a multi-channel ultrasonic flowmeter was designed for measuring the total quantity of coal transported by pipeline. The Doppler signal was measured and analyzed by using mixed-frequency technique and FFT, and some designed circuits and signal measurement process were also offered.
