蒸汽流量計工作原理:
渦街流量傳感器是以卡門(Kaman)和斯特勞哈(Strouhsl)有關旋渦的產生和旋渦與流速關系的理論來測量流量的。當介質以一定速度流過三角柱體時,在三角柱體兩側后面產生一個交替排列的旋渦帶,稱之為“卡門渦街"(見下圖)。

 由于旋渦發生體兩側交替產生旋渦,于是在發生體兩側產生壓力脈動,從而使檢測體產生交變壓力,封裝在探頭體內的壓電晶體元件在交變應力的作用下,產生與旋渦同頻率的交變電荷信號,放大器將這種電荷信號進行放大、濾波、整形、zui后輸出頻率與介質流速成正比的脈沖信號(或轉換成4 ~20mA信號),送至積算儀進行處理、顯示和控制。 一定雷諾數范圍內(2×104~7×106篮球比分),旋渦的釋放頻率f與流體流速V及旋渦發生體的迎流面寬度d之間關系式為f=St·v/d,式中St 為斯特勞哈數,它是一個無量綱的系數,只要準確測出頻率f,就可以求得流體流速v,由v求出體積流量。
