style="text-indent:25px">電子渦街流量傳感器的這些知識(shí)你了解嗎？在電子渦街流量傳感器的設(shè)旋渦的發(fā)生頻率為f，被測(cè)介質(zhì)平均流速為，旋渦發(fā)生體迎流面寬度為d，表體通徑為D，即可得到以下關(guān)系式：f=SrU1/d=SrU/md，式中U1--旋渦發(fā)生體兩側(cè)平均流速，m/s；Sr--斯特勞哈爾數(shù)；m--旋渦發(fā)生體兩側(cè)弓形面積與管道橫截面面積之比管道內(nèi)體積流量qv為qv=πD2U/4=πD2mdf/4Sr。K=f/qv=[πD2md/4Sr]-1。式中K--流量計(jì)的儀表系數(shù)，脈沖數(shù)/m3。由上式可以看出流量傳感器的輸出頻率只于旋渦發(fā)生體及管道的形狀尺寸等有關(guān)。電子元件輸出相應(yīng)的脈沖信號(hào)反饋給控制器，由控制器判斷水流量的大小，調(diào)節(jié)控制比例閥的電流，從而通過(guò)比例閥控制燃?xì)鈿饬?，避免燃?xì)鉄崴髟谑褂眠^(guò)程中出現(xiàn)夏暖冬涼的現(xiàn)象。電子壓力開(kāi)關(guān)可以在數(shù)字顯示屏上顯示開(kāi)關(guān)的各種設(shè)置。</p><div
