電磁流量計(jì)一、電磁流量計(jì)的基本原理電磁流量計(jì)的基本原理是法拉第電磁感應(yīng)定律，即導(dǎo)體在磁場(chǎng)中切割磁力線運(yùn)動(dòng)時(shí)在其兩端產(chǎn)生感應(yīng)電動(dòng)勢(shì)。導(dǎo)電性液體在垂直于磁場(chǎng)的非磁性測(cè)量管內(nèi)流動(dòng)，與流動(dòng)方向垂直的方向上產(chǎn)生與流量成比例的感應(yīng)電勢(shì)，電動(dòng)勢(shì)的方向按“弗來(lái)明右手規(guī)則”。電磁流量計(jì)由流量傳感器和轉(zhuǎn)換器兩大部分組成。，測(cè)量管上下裝有激磁線圈，通激磁電流后產(chǎn)生磁場(chǎng)穿過(guò)測(cè)量管，一對(duì)電極裝在測(cè)量
