為獲得正常測量精確度，電磁流量傳感器上游也要有一定長度直管段，但其長度與大部分其它流量儀表相比要求較低。90o彎頭、T形管、同心異徑管、全開閘閥后通常認為只要離電極中心線不是傳感器進口端連接面5倍直徑5D長度的直管段，不同開度的閥則需10D；下游直管段為2～3D或無要求；但要防止蝶閥閥片伸入到傳感器測量管內(nèi)。各標(biāo)準(zhǔn)或檢定規(guī)程所提出上下游直管段長度亦不一致，匯集如表2所示，要求比通常要求高。三菱伺服驅(qū)動器MR-J2S-100A這是由于為保證達到當(dāng)前0.5級精度儀表的要求。 擾流件名稱 標(biāo)準(zhǔn)或檢定規(guī)程號 ISO 6817 ISO 9104 JIS B7554 ZBN 12007 JJG 198 上游 彎管、形管、全開閘閥、漸擴管 10D 或制造廠規(guī)定 10D 5D 5D 10D 漸縮管 可視作直管 其他各種閥 10D 下游 各類 未提要求 5D 未提要求 2D 2D 如閥能開使用時，應(yīng)按閥截流方向和電極軸成45o角度安裝，則附加誤差可大為減少。
