    一、電磁流量計維護之零點檢查和調整：

    另一個是電解切削工藝驗裝置上，用電磁流量計控製飽和食鹽水流量
，間隙使用一段時期後發現流量信號漸漸減弱，2個月後信號為零。原因是電解切削過程中氧化鐵沉積管壁，形成短路所致。清除層積即立即恢複正常。

    二、電磁流量計維護之定期檢查傳感器電性能：

，cizhiduiyihoupanduanchuanganqiguzhangyuanyin（如沉積層是導電的還是絕緣的）是有用的。

    其次，將傳感器放空液體
，擦淨內壁
，待完全幹燥後用兆歐計測量兩電極和接地端子間的電阻。

    最後，檢查激磁線圈絕緣電阻，卸下傳感器激磁線圈，將端子與轉換器間接線，用兆歐計測量線圈的絕緣電阻。
