E+H 電磁流量計(jì)50W2H-H50A1A10A7AW測(cè)量原理依據(jù)于法拉第電磁感應(yīng)定律,。流量計(jì)測(cè)量管是一內(nèi)襯絕緣材 料的非導(dǎo)磁合金導(dǎo)管,。兩只電極與軸流方向垂直穿透關(guān)閉固定在測(cè)量管上，其電極頭 與襯里內(nèi)表面基于平齊,。當(dāng)勵(lì)磁線圈由雙向發(fā)生方波脈沖勵(lì)磁時(shí),，即在與測(cè)量管軸線 垂直方向上產(chǎn)生一磁能量密度為 B 的工作磁場(chǎng)。此時(shí),，如果具有一定電導(dǎo)率的流體流 經(jīng)測(cè)量管,，將切割磁力線感應(yīng)出電動(dòng)勢(shì) E。電動(dòng)勢(shì) E 正比于磁通量密度 B,，測(cè)量管內(nèi)徑與平均流速 V的乘積,。電動(dòng)勢(shì) E（流量信號(hào)）由電極檢出并通過電纜送至轉(zhuǎn)換器。
