，確保在新介質加入下，流體流經電磁流量計更加的均勻與平穩。
    其次
，在對電磁流量計進行安裝的過程當中，需要確保流量計測量管內部充滿流動流體。主要依據在於：在(zai)電(dian)磁(ci)流(liu)量(liang)計(ji)對(dui)管(guan)道(dao)內(nei)部(bu)流(liu)量(liang)水(shui)平(ping)進(jin)行(xing)測(ce)量(liang)的(de)過(guo)程(cheng)當(dang)中(zhong)

、可靠運行，就需要設置一個零電位的基準點作為參照。故而，在此過程當中，接液處理的核心在於：將管道內部導電液體接地設置為零電位的基準點參照；而同時接地處理的核心則在於：避(bi)免(mian)電(dian)磁(ci)流(liu)量(liang)計(ji)在(zai)測(ce)量(liang)流(liu)體(ti)流(liu)速(su)過(guo)程(cheng)當(dang)中(zhong)受(shou)幹(gan)擾(rao)影(ying)響(xiang)，並(bing)對(dui)電(dian)磁(ci)流(liu)量(liang)計(ji)進(jin)行(xing)合(he)理(li)的(de)安(an)全(quan)保(bao)護(hu)。與(yu)此(ci)同(tong)時(shi)，接(jie)地(di)處(chu)理(li)還(hai)能(neng)夠(gou)使(shi)靜(jing)電(dian)感(gan)應(ying)以(yi)及(ji)電(dian)磁(ci)感(gan)應(ying)所(suo)可(ke)能(neng)誘(you)發(fa)的(de)噪(zao)聲(sheng)電(dian)壓(ya)得(de)到(dao)有(you)效(xiao)的(de)抑(yi)製(zhi)，剔(ti)除(chu)對(dui)測(ce)量(liang)數(shu)據(ju)的(de)幹(gan)擾(rao)。通(tong)過(guo)對(dui)接(jie)地(di)電(dian)阻(zu)水(shui)平(ping)的(de)控(kong)製(zhi)，使(shi)回(hui)路(lu)雜(za)散(san)電(dian)流(liu)壓(ya)降(jiang)水(shui)平(ping)明(ming)顯(xian)降(jiang)低(di)
