電磁流量計的結(jié)構(gòu)主要由磁路系統(tǒng)、測量導(dǎo)管、電極、外殼、襯里和轉(zhuǎn)換器等部分組成。 </p> <p> 電極：其作用是引出和被測量成正比的感應(yīng)電勢信號。電極一般用非導(dǎo)磁的不銹鋼制成，且被要求與襯里齊平，以便流體通過時不受阻礙。它的安裝位置宜在管道的垂直方向，以防止沉淀物堆積在其上面而影響測量精度。 </p> <p> 外殼：應(yīng)用鐵磁材料制成，是分配制度勵磁線圈的外罩，并隔離外磁場的干擾。 </p> <p> 襯里：在測量導(dǎo)管的內(nèi)側(cè)及法蘭密封面上，有一層完整的電絕緣襯里。它直接接觸被測液體，其作用是增加測量導(dǎo)管的耐腐蝕性，防止感應(yīng)電勢被金屬測量導(dǎo)管管壁短路。襯里材料多為耐腐蝕、耐高溫、耐磨的聚四氟乙烯塑料，寧夏超聲流量計、陶瓷等，寧夏超聲流量計。 </p> <p> 轉(zhuǎn)換器：由液體流動產(chǎn)生的感應(yīng)電勢信號十分微弱，受各種干擾因素的影響很大，轉(zhuǎn)換器的作用就是將感應(yīng)電勢信號放大并轉(zhuǎn)換成統(tǒng)一的標(biāo)準(zhǔn)信號并yizhi主要的干擾信號。其任務(wù)是把電極檢測到的感應(yīng)電勢信號Ex經(jīng)放大轉(zhuǎn)換成統(tǒng)一的標(biāo)準(zhǔn)直流信號，寧夏超聲流量計。隨著集成電路技術(shù)的迅速發(fā)展，具有鎖相環(huán)路技術(shù)的超聲（波）流量計也得到了普遍應(yīng)用。寧夏超聲流量計</p><div

style="text-indent:25px">熱式流量計采用熱擴散原理，熱擴散技術(shù)是一種在苛刻條件下性能優(yōu)良、可靠性高的技術(shù)。熱式流量計有兩個溫度傳感器被置于介質(zhì)中時，其中一個傳感器被加熱到環(huán)境溫度以上的的溫度，另一個溫度傳感器用于感應(yīng)介質(zhì)溫度。介質(zhì)流速增加，介質(zhì)帶走的熱量增多，兩個溫度傳感器的溫度差將隨介質(zhì)的流速變化而變化，根據(jù)溫度差與介質(zhì)流速的比例關(guān)系，可得出流體的流量Q。熱式流量計目前絕大部分用于測量氣體，只有少量熱式流量計用于測量微小液體流量。金屬管浮子流量計分類渦輪流量計一般由傳感器和顯示儀兩部分組成，也可做成整體式。</p><div

</p><p> 電磁流量計廣應(yīng)用于污水，氟化工，生產(chǎn)用水，自來水行業(yè)以及醫(yī)藥，鋼鐵等等諸多方面。由于原理決定了它只能測導(dǎo)電液體。雖說它在可靠性和穩(wěn)定性方面都比其它種類的流量計要好許多，但客戶在實際使用過程中，還是會發(fā)生一些問題，下面我就電磁流量計在選型和安裝上詳細(xì)說一下：一，和其它流量計一樣，雖然電磁流量計它的測量范圍比是30：1，比渦街流量計和差壓式流量計都要高，但也是有限制的，許多客戶定表時，常常把它和水表相比較，以為可以測量很低的流速，一般情況下，它只能測。所以定貨初期對流量范圍比要搞清楚。定貨時不能按原先管道口徑來定貨，比較好按你實際流量來定儀表口徑。二，和其它流量計一樣，電磁流量計對安裝前后直管道也有要求，只不過比其它類流量計要求更低，但關(guān)健一點要滿足：就是滿管，再滿管。不滿管的情況下容易引起流量計亂跳：三，和其它流量計一樣，電磁流量計也有防護等級，一般一體式的防護等級為IP65，分體式的為IP68(針對傳感器而言)，如果客戶對儀表安裝環(huán)境有要求，安裝地點在地下陰井或其它一些潮濕的地方，建議客戶選用分體式的。以免選錯對儀表造成損害。流量計中正在更多地引入電子技術(shù)，如數(shù)字信號處理(DSP)和微處理器，這使得流量計具備了自診斷功能。</p><div

為了改善渦流與流場畸變的影響，流量計安裝的前、后直管段長度有一定要求，否則會影響測量精度（也可安裝整流器，盡量避免在靠近調(diào)節(jié)閥和半開閥門之后安裝）。 </p> <p> 2．對工藝管的要求: </p> <p> 流量計對安裝點的上、下游工藝管有一定的要求，否則影響測量精度。 </p> <p> a．上、下游工藝管的內(nèi)徑與傳感器的內(nèi)徑相同，并應(yīng)滿足：0.98DN≤D≤1.05DN（式中DN：傳感器內(nèi)徑，D：工藝管內(nèi)徑）; </p> <p> b．工藝管與傳感器必須同心，同軸偏差應(yīng)不大于0.05DN. </p> <p> 3．旁通管的要求: </p> <p> 為了方便檢修流量計，比較好為流量計安裝旁通管，另外，對重污染流體及流量計需清而流體不能停止的，必須安裝旁通管。 </p> <p> a．方便流量計的檢修; </p> <p> b．對重污染流體必須安裝; </p> <p> c．流體不能停止而流量計需清洗. 為了使電磁流量計的傳感小型化和改善信噪比，出現(xiàn)了用非均勻磁場和低頻勵磁方式的電磁流量計。金屬管浮子流量計分類</p><p style="text-indent:25px">流量測量，在1738年，瑞士有名的物理學(xué)家丹尼爾·伯努利以伯努利方程為基礎(chǔ)，利用了差壓法測量了水流量。寧夏超聲流量計</p><p> 一體型電磁流量計是根據(jù)法拉第電磁感應(yīng)定律制定，用來測量導(dǎo)電流體的體積流量。由于獨特的特點已廣地應(yīng)用于工業(yè)上各種導(dǎo)電液體的測量。主要用于化工、造紙、食品、紡織、冶金、環(huán)保、給排水等行業(yè)，與計算機配套可實現(xiàn)系統(tǒng)控制。1．電磁流量計沒有可動部件，也沒有阻流件，不會引起壓力損失，同時也不會引起磨損，阻塞等問題。2．電磁流量計是一體積流量測量儀表，在測量過程中不受被測介質(zhì)的溫度、粘度、密度以及導(dǎo)電率（在一定范圍內(nèi)）的影響。3．電磁流量計的量程范圍寬，可達(dá)1：100。此外，電磁流量計只與被測介質(zhì)的平均流速成正比，而與軸對稱的流動狀態(tài)（層流或紊流）無關(guān)。4．電磁流量計無機械慣性，反應(yīng)靈敏，可以測量瞬時脈動流量，而且線性好，因此可以將測量信號直接用轉(zhuǎn)換器線性的轉(zhuǎn)換成標(biāo)準(zhǔn)信號輸出。LD-T型可就地指示，LD型可遠(yuǎn)距離傳送。寧夏超聲流量計</p><p
