[0043] like Figure 1-11 The measurement of water flow in a trapezoidal channel uses the ultrasonic time propagation method. Multiple layers of underwater transducers at different heights are arranged on the channel wall. The two transducers on each horizontal layer are called a channel. The two transducers in the same channel are arranged one upstream and the other downstream. The spatial angle between the line connecting the transducers and the central axis of the channel is the channel angle; the length of the line connecting a pair of transducers in the same channel is the channel length of the channel.

Four transducers are arranged on each transducer slope bracket, and the vertical distances between the center of the transducer and the channel bottom are fixed at 0.5m, 1m, 1.5m, and 2m respectively.
