德(de)國(guo)進口（非導電液體(ti)）E+H渦(wo)(wo)(wo)(wo)街(jie)流(liu)量計原(yuan)理：在流(liu)體(ti)中(zhong)設置三(san)角(jiao)柱型旋(xuan)渦(wo)(wo)(wo)(wo)發(fa)生(sheng)(sheng)體(ti)，則(ze)(ze)從旋(xuan)渦(wo)(wo)(wo)(wo)發(fa)生(sheng)(sheng)體(ti)兩側交(jiao)替地產生(sheng)(sheng)有規則(ze)(ze)的旋(xuan)渦(wo)(wo)(wo)(wo)，這(zhe)種(zhong)旋(xuan)渦(wo)(wo)(wo)(wo)稱為卡門旋(xuan)渦(wo)(wo)(wo)(wo)，旋(xuan)渦(wo)(wo)(wo)(wo)列在旋(xuan)渦(wo)(wo)(wo)(wo)發(fa)生(sheng)(sheng)體(ti)下游非對稱地排列。

渦街流(liu)(liu)(liu)(liu)量(liang)(liang)計是根據(ju)卡門(men)渦街原理（Kármán Vortex Street）測量(liang)(liang)氣體(ti)、蒸汽或(huo)液體(ti)的體(ti)積(ji)流(liu)(liu)(liu)(liu)量(liang)(liang)、標(biao)況(kuang)的體(ti)積(ji)流(liu)(liu)(liu)(liu)量(liang)(liang)或(huo)質量(liang)(liang)流(liu)(liu)(liu)(liu)量(liang)(liang)的體(ti)積(ji)流(liu)(liu)(liu)(liu)量(liang)(liang)計。并可作為流(liu)(liu)(liu)(liu)量(liang)(liang)變(bian)送器應用于(yu)自動化(hua)控制系統(tong)中。

渦街(jie)流(liu)(liu)量(liang)計是應用流(liu)(liu)體(ti)振蕩原理來測量(liang)流(liu)(liu)量(liang)的(de)，流(liu)(liu)體(ti)在管(guan)道中經過渦街(jie)流(liu)(liu)量(liang)變送(song)器時，在三角(jiao)柱的(de)旋(xuan)(xuan)渦發(fa)生(sheng)體(ti)后(hou)上下交替產生(sheng)正比于流(liu)(liu)速的(de)兩列(lie)旋(xuan)(xuan)渦，旋(xuan)(xuan)渦的(de)釋放(fang)頻率與流(liu)(liu)過旋(xuan)(xuan)渦發(fa)生(sheng)體(ti)的(de)流(liu)(liu)體(ti)平均速度(du)及旋(xuan)(xuan)渦發(fa)生(sheng)體(ti)特征(zheng)寬(kuan)度(du)有關，可(ke)用下式(shi)表(biao)示(shi)：

式中:為(wei)旋渦的(de)(de)釋放(fang)頻率(lv)，單位(wei)為(wei)Hz；v為(wei)流(liu)過旋渦發(fa)生(sheng)體(ti)(ti)的(de)(de)流(liu)體(ti)(ti)平均速度，單位(wei)為(wei)m/s；d為(wei)旋渦發(fa)生(sheng)體(ti)(ti)特征寬度，單位(wei)為(wei)m；Sr為(wei)斯特勞(lao)哈爾數（Strouhal number），無量(liang)綱(gang)，它(ta)的(de)(de)數值范圍為(wei)0.14－0.27。

St是雷諾數(shu)的函數(shu)。

當雷諾數(shu)Re在范圍內，St值約為0.2。在測量(liang)中，要盡量(liang)滿足(zu)流體的雷諾數(shu)在，此時旋渦頻率。

由此，通過(guo)測量(liang)(liang)旋(xuan)渦頻(pin)率(lv)就可以計算出流(liu)過(guo)旋(xuan)渦發生體(ti)(ti)的流(liu)體(ti)(ti)平(ping)均速(su)度v，再由式(shi)可以求出流(liu)量(liang)(liang)q，其中A為流(liu)體(ti)(ti)流(liu)過(guo)旋(xuan)渦發生體(ti)(ti)的截面積。

的釋放頻率，單位為Hz；v為流過旋(xuan)渦(wo)發生體的流體平(ping)均速度，單位為m/s；d為旋(xuan)渦(wo)發生體特(te)征寬度，單位為m；Sr為斯特(te)勞哈爾數（Strouhal number），無量綱(gang)，它的數值(zhi)范圍(wei)為0.14－0.27。

St是雷諾數的(de)函數。

當雷諾數Re在(zai)范圍內，St值約為(wei)0.2。在(zai)測量(liang)中，要(yao)盡量(liang)滿足流體的雷諾數在(zai)，此時旋渦頻率。

由(you)此，通過測量旋(xuan)(xuan)渦(wo)(wo)頻率就可以計算出(chu)流(liu)過旋(xuan)(xuan)渦(wo)(wo)發生(sheng)體(ti)(ti)的(de)流(liu)體(ti)(ti)平(ping)均速度v，再由(you)式可以求(qiu)出(chu)流(liu)量q，其中(zhong)A為流(liu)體(ti)(ti)流(liu)過旋(xuan)(xuan)渦(wo)(wo)發生(sheng)體(ti)(ti)的(de)截面積。德國原裝E+H渦街流(liu)量計
