在设计流量试验装置时,首要任务是确定装置液压系统的水头、流量和水力特性之间最佳的而又容易实现的关系。这些关系确定了装置的应用范围,也是设计装置元件和预测计量性能的原始资料。可以通过控制选择上述参数及其关系的计算方法来解决上面提出的问题,而这里所运用的方法叫做通用(意思是流量装置的类型无关紧要)运行特性。这类问题可在流量装置的鉴定过程中加以讨论 The primary task in designing a flow test rig is to determine the best and easy relationship between the head, flow, and hydraulic characteristics of the plant’s hydraulic system. These relationships define the application of the device and are the source for designing the device components and predicting the performance of the measurement. The problem raised above can be solved by controlling the calculation of the above parameters and their relationship, and the method used here is called general purpose (meaning that the type of flow device does not matter). Such problems can be discussed during the qualification of flow devices
