style="text-indent:25px">電磁流量計(jì)和超聲波流量計(jì)的主要區(qū)別，安裝、維護(hù)、檢定成本不同：超聲波流量計(jì)適用于較大型圓形管道和矩形管道，且原理上不受管徑限制，其造價(jià)基本上與管徑無(wú)關(guān)。對(duì)于較大型管道不僅帶來(lái)方便，可認(rèn)為在無(wú)法實(shí)現(xiàn)實(shí)流動(dòng)校驗(yàn)的情況較是優(yōu)先考慮的選擇方案。超聲流量計(jì)可作非接觸測(cè)量。夾裝式換能器超聲流量計(jì)可無(wú)需停流動(dòng)截管安裝，只要在既設(shè)管道外部安裝換能器即可。這是超聲流量計(jì)在工業(yè)用流量?jī)x表中具有的獨(dú)特優(yōu)點(diǎn)，因此可作移動(dòng)性(即非定點(diǎn)固定安裝)測(cè)量，適用于管網(wǎng)流動(dòng)動(dòng)狀況評(píng)估測(cè)定超聲流量計(jì)為無(wú)流動(dòng)動(dòng)阻撓測(cè)量，無(wú)額外壓力損失。嘉興渦輪流量計(jì)訂購(gòu)污水流量計(jì)使用的直管段還要注意不能有負(fù)壓，以防止襯里材料脫落。</p><div

style="text-indent:25px">智能電磁流量計(jì)維護(hù)之定期檢查傳感器電性能：首先，粗略地測(cè)量電極間電阻。斷開(kāi)傳感器與轉(zhuǎn)換器間信號(hào)連線，傳感器內(nèi)充滿液體，用萬(wàn)用表測(cè)量?jī)呻姌O與接地端的電阻值，是否在制造廠規(guī)定值范圍內(nèi)，且所測(cè)得兩值較大體相同。記錄較靠前測(cè)量的電阻值，此值對(duì)以后判斷傳感器故障原因（如沉積層是導(dǎo)電的還是絕緣的）是有用的。其次，將傳感器放空液體，擦凈內(nèi)壁，待完全干燥后用兆歐計(jì)測(cè)量?jī)呻姌O和接地端子間的電阻。后，檢查激磁線圈絕緣電阻，卸較傳感器激磁線圈，將端子與轉(zhuǎn)換器間接線，用兆歐計(jì)測(cè)量線圈的絕緣電阻。</p><p style="text-indent:25px">電磁流量計(jì)噪音分析：流動(dòng)體摩擦襯里和電極，流動(dòng)體中發(fā)生的正離子和負(fù)離子從電解液中分離出來(lái)。內(nèi)襯和電極表面越粗糙，游離離子濃度越高。一部分離子在電極信號(hào)電場(chǎng)的作用較向電極移動(dòng)，從而形成噪聲電壓，這就是流動(dòng)動(dòng)噪聲。在低電導(dǎo)率測(cè)試中，流動(dòng)動(dòng)噪聲的影響是很明顯的。流動(dòng)場(chǎng)噪聲與外電場(chǎng)強(qiáng)度有關(guān)，當(dāng)流動(dòng)速較較大時(shí)，感應(yīng)信號(hào)越較大，噪聲越較大，輸出的穩(wěn)定性越差。流動(dòng)體的電導(dǎo)率和pH值的急劇變化也會(huì)形成流動(dòng)動(dòng)噪聲，上游流量計(jì)加藥性能的測(cè)量不穩(wěn)定性就是一例。其原因是不同介質(zhì)在不均勻混合時(shí)，流動(dòng)體中很容易分離出正負(fù)離子，部分離子會(huì)受到電極信號(hào)電場(chǎng)的影響向電極移動(dòng)，產(chǎn)生流動(dòng)動(dòng)噪聲電壓，導(dǎo)致輸出不穩(wěn)定。由于在襯里和電極附近的高流動(dòng)速流動(dòng)流動(dòng)體的層流動(dòng)邊界層厚度變得非常薄，因此襯里和電極的粗糙度值都超過(guò)了流動(dòng)速層邊界層的厚度，流動(dòng)體沖擊這部分的粗糙度值，就會(huì)發(fā)生流動(dòng)速擴(kuò)散和突變。部分流動(dòng)速分量與測(cè)量管中心軸向相同(或相反)，受信號(hào)權(quán)函數(shù)的影響，對(duì)電極信號(hào)產(chǎn)生較較大的正向影響，這就是較高流動(dòng)速噪聲。流量計(jì)又分為有差壓式流量計(jì)、轉(zhuǎn)子流量計(jì)、節(jié)流式流量計(jì)、細(xì)縫流量計(jì)、容積流量計(jì)、電磁流量計(jì)等。</p><div
