摘要
介绍了万家寨引黄工程中使用的ACCUSONIC 75 0 0超声波流量计的测量原理以及超声波换能器的安装参数 ,进而对影响流量测量的误差源进行了具体分析 ,并对超声波法和现场使用的另外两种方法———流速仪法和薄壁堰法的测量结果进行了对比分析 ,3种测量方法得到的流量曲线非常一致。
The principle and installation parameters of ACCUSONIC 7500 ultrasonic flowmeter used in the Yellow River Diversion Project (YRDP) are introduced. The error sources are analyzed in detail, and the measured results of the ultrasonic flowmeter are compared with the results of other two methods -- current meter and thin plate weir. The flux curves measured by the three methods are consistent.
