德國進口(kou)（非導(dao)電液(ye)體）E+H渦(wo)(wo)街(jie)流量(liang)計原(yuan)理：在流體中設(she)置三角柱型旋(xuan)(xuan)渦(wo)(wo)發生(sheng)(sheng)(sheng)體，則從旋(xuan)(xuan)渦(wo)(wo)發生(sheng)(sheng)(sheng)體兩側交替地產生(sheng)(sheng)(sheng)有(you)規則的旋(xuan)(xuan)渦(wo)(wo)，這種旋(xuan)(xuan)渦(wo)(wo)稱為卡門旋(xuan)(xuan)渦(wo)(wo)，旋(xuan)(xuan)渦(wo)(wo)列在旋(xuan)(xuan)渦(wo)(wo)發生(sheng)(sheng)(sheng)體下游非對(dui)稱地排(pai)列。

渦(wo)街(jie)流(liu)(liu)量(liang)(liang)(liang)計是根據卡門(men)渦(wo)街(jie)原理（Kármán Vortex Street）測量(liang)(liang)(liang)氣體(ti)(ti)、蒸汽或液(ye)體(ti)(ti)的(de)體(ti)(ti)積流(liu)(liu)量(liang)(liang)(liang)、標況(kuang)的(de)體(ti)(ti)積流(liu)(liu)量(liang)(liang)(liang)或質量(liang)(liang)(liang)流(liu)(liu)量(liang)(liang)(liang)的(de)體(ti)(ti)積流(liu)(liu)量(liang)(liang)(liang)計。并(bing)可(ke)作(zuo)為流(liu)(liu)量(liang)(liang)(liang)變送器應用于自動化控制系統中(zhong)。

渦(wo)(wo)街流(liu)量計是應用(yong)流(liu)體(ti)振蕩原理來測量流(liu)量的(de)，流(liu)體(ti)在管道中經過渦(wo)(wo)街流(liu)量變送(song)器時，在三(san)角柱的(de)旋(xuan)(xuan)渦(wo)(wo)發生(sheng)體(ti)后(hou)上下(xia)交替(ti)產生(sheng)正比于流(liu)速的(de)兩列(lie)旋(xuan)(xuan)渦(wo)(wo)，旋(xuan)(xuan)渦(wo)(wo)的(de)釋(shi)放頻率與(yu)流(liu)過旋(xuan)(xuan)渦(wo)(wo)發生(sheng)體(ti)的(de)流(liu)體(ti)平均速度(du)及旋(xuan)(xuan)渦(wo)(wo)發生(sheng)體(ti)特征寬度(du)有關，可用(yong)下(xia)式(shi)表示：

式中(zhong):為旋(xuan)(xuan)渦(wo)的釋放頻率，單位為Hz；v為流過旋(xuan)(xuan)渦(wo)發(fa)生體的流體平均(jun)速度，單位為m/s；d為旋(xuan)(xuan)渦(wo)發(fa)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，它的數值范圍為0.14－0.27。

St是雷(lei)諾數的函數。

當雷(lei)諾數(shu)Re在范圍(wei)內(nei)，St值(zhi)約為0.2。在測量(liang)中(zhong)，要盡量(liang)滿足(zu)流體的(de)雷(lei)諾數(shu)在，此時旋渦頻(pin)率。

由(you)(you)此，通過(guo)測(ce)量旋渦頻率(lv)就可以計算出流過(guo)旋渦發(fa)生(sheng)體(ti)(ti)的流體(ti)(ti)平均(jun)速度v，再(zai)由(you)(you)式可以求出流量q，其中A為流體(ti)(ti)流過(guo)旋渦發(fa)生(sheng)體(ti)(ti)的截(jie)面積。

的(de)釋放頻率，單位為Hz；v為流(liu)過(guo)旋渦發生(sheng)體(ti)(ti)的(de)流(liu)體(ti)(ti)平均速度，單位為m/s；d為旋渦發生(sheng)體(ti)(ti)特(te)征(zheng)寬(kuan)度，單位為m；Sr為斯特(te)勞哈爾數（Strouhal number），無量綱，它的(de)數值(zhi)范(fan)圍為0.14－0.27。

St是雷諾(nuo)數的(de)函(han)數。

當雷諾數Re在范圍內，St值約為(wei)0.2。在測量中(zhong)，要盡量滿足流體的雷諾數在，此(ci)時旋渦頻率。

由此，通過測量(liang)旋(xuan)渦(wo)(wo)頻率就可以(yi)計算(suan)出流(liu)過旋(xuan)渦(wo)(wo)發生體(ti)(ti)的(de)流(liu)體(ti)(ti)平均速度v，再由式可以(yi)求出流(liu)量(liang)q，其中(zhong)A為流(liu)體(ti)(ti)流(liu)過旋(xuan)渦(wo)(wo)發生體(ti)(ti)的(de)截面積。德國(guo)原裝E+H渦街流(liu)量計(ji)
