Controling and measurement of water for agricultural irrigation widespread inefficiency, high accuracy is not the situation, based on multi-channel ultrasonic transit-time flowmeter design and complete hardware design and software design. Program uses a high-voltage power driver ultrasonic transmitter circuit, for receiving and processing signals from the microprocessor Cortex-M4k60 be calculated according to the signal information, the conclusion that the open channel flow measurement.
