原理：所有的電磁流量計(jì)都是基于法拉第電磁感應(yīng)定律設(shè)計(jì)：
UM=B.V.D.K測量電壓產(chǎn)生于各流體的流向正交的電磁場。由兩個(gè)電極
獲得測量電壓
B=磁通過密度，穿過流體介質(zhì)并正交于流體流向
V=介質(zhì)流速
D=測量管道內(nèi)徑
K=比例系數(shù)或傳感器常數(shù)
電磁流量計(jì)的功能各測量原理
電磁流量計(jì)通常由一個(gè)內(nèi)表面不導(dǎo)電的測量管、串聯(lián)連接且沿管道
徑向安裝的電磁線圈以及至少兩個(gè)電極組成。電極插入管壁并與被
測介質(zhì)相接觸。電流通過的磁場線圈產(chǎn)生的一個(gè)脈沖電磁場，其磁
通密度B垂直于管道軸線
診斷： 明確的文字標(biāo)識(shí)和故障記錄座斷功能是儀表的基本功能
故障分類：功能；報(bào)警；持久性和重大錯(cuò)誤，變送器自檢：線圈和
電極測試過載
空管：半滿管；低導(dǎo)電率；電極污垢
校驗(yàn)-步驟
SITRANS F M MAGFLO流量計(jì)的校驗(yàn)過和包括下列幾個(gè)測試步驟
變送器測試
流量計(jì)和電纜絕緣測試
傳感器磁性測試。
