style="text-indent:25px">電磁流量計應用一直都非常，由于是為供水企業(yè)水計量商業(yè)專門設計的，具有防水、防腐、防干擾、防雷擊的能力。那么在電磁流量計使用中也肯定有一些題目，我們就收集來分析一下。一、傳感器接地的題目電磁流量計傳感器電極檢測的流量信號是毫伏級，且以傳感器內(nèi)流體的電位為基準的，所以外來干擾對它的影響很大，因而，良好的接地很大程度上決定著流量計的丈量正確度。被測的流體本身作為電導體，必需排除其他不相關(guān)的電磁干擾。電極檢測出的電勢信號，不受外界寄生電勢的干擾。對傳感器應有良好的單獨接地線，接地電阻小于10Ω。在連接傳感器的管道內(nèi)若涂有絕緣層或長短金屬管道時，傳感器兩側(cè)應裝有接地環(huán)。泰州液體渦輪流量計供貨廠</p></p><br
