E=KBdV </p> <p> 流量Q 為： Q=3600×V×S </p> <p> 式中：K—儀表系數(shù) </p> <p> B—磁感應(yīng)強度(T) </p> <p> d—電極間距(m) </p> <p> V—流體平均流速(m/s) </p> <p> S—導(dǎo)管內(nèi)截面積(m2) </p> <p> 測量流量時，導(dǎo)電性液體以流速V 流過垂直于流動方向的磁場，自貢電磁流量計供應(yīng)，導(dǎo)電性液體的流動感應(yīng)出一個與平均流速成正比的電壓，其感應(yīng)電壓信號通過與液體直接接觸的電極檢出，自貢電磁流量計供應(yīng)，自貢電磁流量計供應(yīng)。對于同前列量計S、B、d 為常量，所以流量與感應(yīng)電動勢E(或流速V)的大小成正比。自貢電磁流量計供應(yīng)</p><div

分體式電磁流量計測量原理是基于法拉第電磁感應(yīng)定律，分體式電磁流量計由傳感器和轉(zhuǎn)換器組成，傳感器安裝在測量管道上，轉(zhuǎn)換器被安裝在離傳感器30米內(nèi)或100米內(nèi)的場合，兩者間由屏蔽電纜連接。 </p> <p> 產(chǎn)品特點 </p> <p> 1、測量不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的影響； </p> <p> 2、測量管內(nèi)無阻礙流動部件，無壓損，直管段要求較低； </p> <p> 3、系列公稱通徑DN15～DN3000。傳感器襯里和電極材料有多種選擇； </p> <p> 4、轉(zhuǎn)換器采用新穎勵磁方式，功耗低、零點穩(wěn)定。流量范圍度可達1500：1； </p> <p> 5、轉(zhuǎn)換器可與傳感器組成一體型或分離型； </p> <p> 6、轉(zhuǎn)換器采用16位高性能微處理器，2x16LCD顯示，參數(shù)設(shè)定方便，編程可靠； </p> <p> 7、流量計為雙向測量系統(tǒng)，內(nèi)裝三個積算器：正向總量、反向總量及差值總量；可顯示．莊、反流量，并具有多種輸出：電 </p> <p> 流、脈沖、數(shù)字通訊、HART； </p> <p> 8、轉(zhuǎn)換器采用表面安裝技術(shù)(SMT)，具有自檢和自診斷功能自貢電磁流量計供應(yīng)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="自貢電磁流量計供應(yīng),電磁流量計"

被測液體電導(dǎo)率≥5μs/cm，配合各種襯里材料，可適用于測量各種酸、堿、鹽溶液及泥漿、礦漿、紙漿等介質(zhì)的流量。 </p> <p> 2，流量的測量不受流體的密度、粘度、溫度、壓力和電導(dǎo)率變化的影響，傳感器感應(yīng)電壓信號 </p> <p> 與平均流速呈線性關(guān)系，測量精度高。 </p> <p> 3，電磁流量計合理選用襯里及電極材料，可實現(xiàn)良好的耐腐蝕性和耐磨性。 </p> <p> 4，低頻矩形波激磁，不受工頻及現(xiàn)場各種雜散干擾的影響，工作穩(wěn)定可靠。 </p> <p> 5，不受流體方向影響，正反向均可計量。 </p> <p> 6，量程比1：120(0.1m/s～12m/s)，滿量程流速范圍寬。 </p> <p> 7，漢字液晶背光顯示，可在線修改參數(shù)，操作簡單方便。 </p> <p> 8，電磁流量計具有空管測量、報警功能，并能適應(yīng)不同的流體介質(zhì)。 </p> <p> 9，掉電時間記錄功能，自動記錄儀表系統(tǒng)電源間斷時間，補算漏計流量。 </p> <p> 10，小時總量記錄功能，以小時為單位記錄流量總量，適用于分時計量制。 </p><p> 夾持式電磁流量計安裝要求 </p> <p> 為了您正確的測量，在選擇管道上位置時應(yīng)注意以下幾點要求： </p> <p> (1)傳感器既可在直管道上安裝，也可在水平或傾斜管道上安裝，但要求二電極的中心連線處于水平狀態(tài)。 </p> <p> (2)介質(zhì)在安裝位置應(yīng)該滿管流動，避免不滿管及氣體附著在電極上。 </p> <p> (3)對于液固兩相流體，采用垂直安裝，使傳感器襯里磨損均勻，延長使用壽命。 </p> <p> (4)流量計安裝位置介質(zhì)不滿時，可采取抬高流量計后端管路的方法，使其滿管，嚴禁在管道點和出水口安裝流量計。 </p> <p> (5)修改管道的安裝方法：當(dāng)介質(zhì)流速達不到要求時，應(yīng)當(dāng)選用較小口徑的流量計，這時應(yīng)使用異徑錐管或修改部分管道，使其與傳感器同口徑，但前后直管段至少須滿足前直管段≥10DN、后直管道≥5DN(DN 為管徑)。 </p> <p> (6)前后直管段為流量計前≥10DN,后端≥5DN。 </p><div

電磁流量計按轉(zhuǎn)換器與傳感器組裝方式分類，有分體式和一體型。分體型電磁流量計是電磁流量計普遍應(yīng)用的形式，如下圖所展示的，傳感器接入管道，轉(zhuǎn)換器裝在儀表室或人們易于接近的傳感器附近，相距數(shù)十到數(shù)百米。 </p> <p> 為防止外界噪聲侵入，信號電纜通常采用雙芯屏蔽線。測量電導(dǎo)率較低液體而相聚超過30m時，為防止電纜部分電容造成信號衰減，內(nèi)層屏蔽也有要求接上與芯線同電位低阻抗源的屏蔽驅(qū)動。分體型電磁流量計的轉(zhuǎn)換器可遠離現(xiàn)場惡劣環(huán)境，電子部件檢查、調(diào)整和參數(shù)設(shè)定就比較方便。自貢電磁流量計供應(yīng)</p><p
