工作原理：根據(jù)流體振蕩原理來測量流量的，流體在管道中經(jīng)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(chǎn)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(guān)，根據(jù)這種關(guān)系，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，再乘以橫截面積得到流量。 </p> <p> 工作特點：①結(jié)構(gòu)簡單而牢固，無可動部件，可靠性高，長期運(yùn)行十分可靠;②安裝簡單，維護(hù)十分方便;③檢測傳感器不直接接觸被測介質(zhì)，山西長頸噴嘴流量計哪家好，性能穩(wěn)定，壽命長;④輸出是與流量成正比的脈沖信號，山西長頸噴嘴流量計哪家好，無零點漂移，精度高;⑤測量范圍寬，山西長頸噴嘴流量計哪家好，量程比可達(dá)1：10;⑥壓力損失較小，運(yùn)行費(fèi)用低，更具節(jié)能意義。為了智能電磁流量計能夠很好地正常使用，智能電磁流量計傳感器接地一定要安裝好。山西長頸噴嘴流量計哪家好</p><div
