智能型電磁流量計如果在日常使用過程中出現(xiàn)了一些問題，我們就要去認(rèn)真的去找原因。原因很多，主要有下面幾個方面： </p> <p> 一、使用場所的原因 </p> <p> 使用場所如果不太好，比如現(xiàn)場有一些干擾，我們就要想辦法來解決這些問題。比如在接地上用單一地接地，或用傳感器和管道進(jìn)行不導(dǎo)電的辦法；還有就是用屏蔽線給予保護(hù)。 </p> <p> 二、裝配程序的原因 </p> <p> 比如有的用戶把智能電磁流量計在容易有空氣的高處，或者安裝在不經(jīng)常是滿管的地方，或者安裝在流體從上到下的堅著的管子上，這些都會使智能電磁流量計使用出現(xiàn)問題。 </p> <p> 三、測量介質(zhì)的原因 </p> <p> 如果所測量的介質(zhì)不是單單地導(dǎo)電液體，而是液氣混合，天津液體渦輪流量計批發(fā)價格，也就是說測量介質(zhì)里面有許多氣泡，它就會地影響測量信號輸出地穩(wěn)定性。 </p> <p> <br /> </p> <p> 四、長期使用了的智能電磁流量計的內(nèi)管里會積污垢，這樣也會影響電磁流量計的測量效果。 </p> <p> 五、電磁流量計的電源線，要做好防雷電的工作，天津液體渦輪流量計批發(fā)價格。特別是夏天，一定做注意這一點(diǎn)，天津液體渦輪流量計批發(fā)價格。浮子流量計是*次于差壓式流量計應(yīng)用范圍寬廣的一類流量計,特別在小、微流量方面有舉足輕重的作用。天津液體渦輪流量計批發(fā)價格</p><div style="width:100%;text-align:

style="text-align:left;"> <span style="font-size:12px;">渦輪流量計可水平、垂直安裝，垂直安裝時流體方向必須向上。液體應(yīng)充滿管道，不得有氣泡。安裝時，液體流動方向應(yīng)與傳感器外殼上指示流向的箭頭方向一致。安裝時必須使管道內(nèi)流體滿管，才能保證測量精細(xì)。 </span> <p> 流量計上游端至少應(yīng)有10倍公稱通徑長度的直管段，下游端應(yīng)不少于5倍公稱通徑的直管段，其內(nèi)壁應(yīng)光滑清潔，無凹痕、積垢和起皮等缺陷。傳感器的管道軸心應(yīng)與相鄰管道軸心對準(zhǔn)，連接密封用的墊圈不得深入管道內(nèi)腔。不同情況下的直管段要求如下圖。 </p> <p> 同時在安裝時應(yīng)避免管道內(nèi)產(chǎn)生氣泡，否則會影響測量的精度。 </p> <p> 威力巴流量計 </p> <p> 威力巴流量傳感器，是根據(jù)差壓式工作原理、插入式安裝方法設(shè)計的流量傳感器。 </p> <p> 結(jié)構(gòu)特點(diǎn)： </p> <p>

PD流量計,在流量儀表中是精度比較高的一類。它利用機(jī)械測量元件把流體連續(xù)不斷地分割成單個已知的體積部分,根據(jù)測量室逐次重復(fù)地充滿和排放該體積部分流體的次數(shù)來測量流體體積總量。 </p> <p> 容積式流量計按其測量元件分類,可分為橢圓齒輪流量計、刮板流量計、雙轉(zhuǎn)子流量計、旋轉(zhuǎn)活塞流量計、往復(fù)活塞流量計、圓盤流量計、液封轉(zhuǎn)筒式流量計、濕式氣量計及膜式氣量計等。 </p> <p> 優(yōu)點(diǎn): </p> <p> (1)計量精度高; </p> <p> (2)安裝管道條件對計量精度沒有影響; </p> <p> (3)可用于高粘度液體的測量; </p> <p> (4)范圍度寬; </p> <p> (5)直讀式儀表無需外部能源可直接獲得累計,總量,清晰明了,操作簡便。 </p> <p> 缺點(diǎn): </p> <p> (1)結(jié)果復(fù)雜,體積龐大; </p> <p> (2)被測介質(zhì)種類、口徑、介質(zhì)工作狀態(tài)局限性較大; </p> <p> (3)不適用于高、低溫場合; </p> <p> (4)大部分儀表只適用于潔凈單相流體; </p> <p> (5)產(chǎn)生噪聲及振動。 </p> <p> 應(yīng)用概況: </p> <p> 容積式流量計與差壓式流量計、浮子流量計并列為三類使用量比較大的流量計,常應(yīng)用于昂貴介質(zhì)(油品、天然氣等)的總量測量。 </p><p> 電磁流量計的應(yīng)用有一定局限性，它只能測量導(dǎo)電介質(zhì)的液體流量，不能測量非導(dǎo)電介質(zhì)的流量，例如氣體和水處理較好的供熱用水。另外在高溫條件下其襯里需考慮。 </p> <p> 電磁流量計是通過測量導(dǎo)電液體的速度確定工作狀態(tài)下的體積流量。按照計量要求，對于液態(tài)介質(zhì)，應(yīng)測量質(zhì)量流量，測量介質(zhì)流量應(yīng)涉及到流體的密度，不同流體介質(zhì)具有不同的密度，而且隨溫度變化。如果電磁流量計轉(zhuǎn)換器不考慮流體密度，*給出常溫狀態(tài)下的體積流量是不合適的。流體流動帶動渦輪轉(zhuǎn)動，渦輪的轉(zhuǎn)速轉(zhuǎn)換成電脈沖，用二次表顯示出數(shù)據(jù)，反應(yīng)流體流速。</p><div

</p> <p> 缺點(diǎn)： </p> <p> 測量的重復(fù)性、精確度在流量計中屬于中等水平，由于眾多因素的影響錯綜復(fù)雜，精確度難于提高。范圍度窄，由于流量系數(shù)與雷諾數(shù)有關(guān),一般范圍度* 3∶1 ～ 4∶1。有較長的直管段長度要求，一般難于滿足。尤其對較大管徑，問題更加突出；壓力損失大；通常為維持一臺孔板流量計正常運(yùn)行，水泵需要附加動力克服孔板的壓力損失。該附加耗電量可直接由
