Abstract: The accurate and quick flow measurement of U-shape canal plays a great foundation role for planned water use and improving water use efficiency in irrigation area, thus providing a portable flow measurement device is of great importance to promoting canal flow measurement. For this reason, we designed a portable automatic ultrasonic flow measurement device that can detect the water levels at upstream and lower stream and calculate the water surface slope. The measured data can be transferred to the monitoring equipment by the intelligent device controller in wireless way and the users can read the historical and real-time flow data, the purpose of automatic flow-gauging can be achieved.
