（非導電液體）E+H渦街流量計原理：在流體中設置三角柱型旋渦發(fā)生體，則從旋渦發(fā)生體兩側交替地產生有規(guī)則的旋渦，這種旋渦稱為卡門旋渦，旋渦列在旋渦發(fā)生體下游非對稱地排列。

渦街流量計是根據(jù)卡門渦街原理（Kármán Vortex Street）測量氣體、蒸汽或液體的體積流量、標況的體積流量或質量流量的體積流量計。并可作為流量變送器應用于自動化控制系統(tǒng)中。

渦街流量計是應用流體振蕩原理測量流量的，流體在管道中經過渦街流量變送器時，在三角柱的旋渦發(fā)生體后上下交替產生正比于流速的兩列旋渦，旋渦的釋放頻率與流過旋渦發(fā)生體的流體平均速度及旋渦發(fā)生體特征寬度有關，可用下式表示：

式中:為旋渦的釋放頻率，單位為Hz；v為流過旋渦發(fā)生體的流體平均速度，單位為m/s；d為旋渦發(fā)生體特征寬度，單位為m；Sr為斯特勞哈爾數(shù)（Strouhal number），無量綱，它的數(shù)值范圍為0.14－0.27。

St是雷諾數(shù)的函數(shù)。

當雷諾數(shù)Re在范圍內，St值約為0.2。在測量中，要盡量滿足流體的雷諾數(shù)在，此時旋渦頻率。

由此，通過測量旋渦頻率就可以計算出流過旋渦發(fā)生體的流體平均速度v，再由式可以求出流量q，其中A為流體流過旋渦發(fā)生體的截面積。
