Abstract：Aiming at the the situation of widespread inefciency and lowaccuracy in the control and measurement of water for agricultural irrigation, theultrasonic transit-time flowmeter design based on multi-channel was proposed ,andthe hardware and software designs were completed. This program uses ahigh-voltage power driver ultrasonic transmitter circuit to receive and processthe signals,which were then calculated by the microprocessor Cortex-M4k60according to the signal information.Finally, the open channel flow could be measured.
