摘　　要：针对南水北调工程淮安第三抽水站现场测试中流量测量存在的困难,对其流道进行模型试验。通过CFD数值计算对流道模型进行简化。提出超声波流量计在不规则流道中新的安装应用方式,通过模型试验,确定新的安装方式下各声路的计算权重,以及流量计算所需的平均断面面积,得出该安装方式下流量计算公式,为现场测量提供充足的依据,同时也为其它复杂流道的流量测量提供一种新的方法和借鉴。Against the difficulties existing in the flow measurement of Huai＇an third pumping station of South - to - North Water Diversion project, the model experiment to its channel was carried on, the model was simplified through CFD numerical calculation. A new method of ultrasonic flowmeter to work in complicated flow channel was proposed. The weight of each acoustic path in this method through model test and the average area of the section needed in the flow measurement calculation were defined. The formula to measure in this method was got to provides the sufficient basis for the site measurement, and new method and model was povided for other complex pipelines flow measurements .
