| 摘 要： | 提出流量计如何能在流动存在的情况下准确地测出测量。选择正弦脉动流讨论周期性脉动流对涡轮流量计测量精度的影响，认为脉动流频率的大小严重影响涡轮流量计测量精度，涡轮叶片转动惯量和稳态时的叶片转速也对精度有不同程度的影响。

| Abstract: | The paper described how does the flowmeter accurately measure the flow under influence of periodical pulsing. With sine pulsing flow as the basis the influence of periodical pulsing flow to the accuracy of measurement of turbine flowmeter is discussed. The author found that the frequency of the pulsing flow heavily affects the accuracy of measurement offlowmeter. In addition, the rotating inertia of the vane and the stable rotating speed of the vane also affect the accuracy differently. |
