便携式超声波U型渠自动测流装置研究

渠道流量的准确、快捷测量对于农业灌区实行计划用水,提高用水效率具有关健的基础作用,而提供一种便于携带的测流量装置对于推动渠道测流工作具有重要意义。鉴于此,设计了一种便携式超声波U型渠自动测流装置。通过该装置可计算出渠道水面坡度i,再根据谢才公式可以得出流量Q。该装置测得的数据可通过智能设备控制器以无线的方式传输给监控设备,用户可在监控设备上读取流量的历史数据和实时数据,从而可实现自动测流目的。

Research on portable automatic ultrasonic flow measurement device for U-shape canal

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.
