It has a long history using a throttle device to measure the flow volume of fluid in pipe the method has formed normalization at home and abroad the principle is to make the flow bunch form the particial shrink at the place where the throttle part is located so as to produce a static pressure difference then measure and calculate the flow volume at the moment when the fluid is flowing through the throttle device by the static pressure measured this method is based on the law of conservation of energy and the equation of flow continuity
用節流裝置測量管道中流體流量已歷史悠久，在國內、國際上都已標準化，其原理是使流束在節流件處形成局部收縮，產生靜壓力差，通過測量靜壓力差來衡量流體流過節流裝置時的流量大小，這種測量方法是以能量守恆定律和流動連續性方程為基礎的。 -
This paper offers a method that can avoid the incorrect or rough methods mostly accepted now, and this method considers the temperature change along pipeline, the difference of friction loss in turbulence zone and the throttle effect in cross - section of reduced pipe
針對現有的靜態模擬演算法存在的錯誤和不足，提出了一種更為精確的模擬演算法，該演算法除考慮了管道沿線的溫度變化、處于不同的紊流區摩阻損失的大小不同之外，還考慮了變徑管道在變截面處存在節流效應等問題。 -
The simulation shows that the valve throttle area should be little as possible but must be more than 40 % of pipe section area ; when the total length of pipe is same, and the flow quantity is enough, pipe before primary valve should be thin and long, and the pipe after primary valve should be thick and short, the upriver and downriver small pressure fluctuation will badly lead to waterdrammer pressure rising, and spending more time in establishing pressure and flow quantity
模擬表明，閥門過流面積在滿足大於管道截面積40 %的條件下應盡可能小;在管道總長一定並滿足流量要求的條件下，主閥前應採取長而細的管道，閥后則應採用短而粗的管道;上下游微小的壓力波動都會嚴重增大開關閥門引起的水擊，並使壓力、流量的建立需要更長的時間。 -
