摘　　要： 利用π定理推导出孔板、文丘里、电磁及涡轮流量计水力特性。将4种流量计串联组成测试装置进行试验研究,利用软件采集各流量计测试数据,与称重法测量数据进行对比。用Origin软件绘出流量曲线,分析在不同流量条件下各种流量计的准确度和误差率,以期为流量计的选型和应用提供有价值的参考依据。 The hydraulic characteristics of orifice flowmeter, venturi flowmeter, electromagnetic flowmeter and turbine flowmeter are derived by π-principle. The testing device is designed by four flowmeters connected in series. We contrast the flow of four commonly and use software to get datum of flowmeters, which are compared to datum by weighing method. We analyze the accuracy and error rate of the four commonly used flowmeters in detail by flow curves, using origin software under the different flow conditions. The conclusion could be used as a valuable reference for selection and application on the four commonly used flowmeters.
