超聲波流量計是基于超聲波在流動介質(zhì)中傳播的速度等于被測介質(zhì)的平均流速和聲波本身速度的幾何和的原理而設(shè)計的。它也是由測流速來反映流量大小的。超聲波流量計雖然在70年代才出現(xiàn)，但由于它可以制成非接觸型式，并可與超聲波水位計聯(lián)動進(jìn)行開口流量測量，對流體又不產(chǎn)生擾動和阻力，所以很受歡。 </p> <p> 超聲波流量計按測量原理分可分為時差式和多普勒式 </p> <p> 利用時差式原理制造的時差式超聲流量計近年來得到廣泛的關(guān)注和使用，是目前企事業(yè)使用多的一種超聲波流量計。 </p> <p>

2、安裝距離應(yīng)選擇上游大于10倍直管徑、下游大于5倍直管徑以內(nèi)無任何閥門、彎頭、變徑等均勻的直管段，安裝點(diǎn)應(yīng)充分遠(yuǎn)離閥門、泵、高壓電和變頻器等干擾源。 </p> <p> 3、避免安裝在管道系統(tǒng)的比較高點(diǎn)或帶有自由出口的豎直管道上。 </p> <p> 4、對于開口或半滿管的管道，流量計應(yīng)安裝在U型管段處。 </p> <p> 渦街流量計 </p><p> 電磁流量計 </p> <p> 工作原理：基于法拉第電磁感應(yīng)定律。在電磁流量計中，測量管內(nèi)的導(dǎo)電介質(zhì)相當(dāng)于法拉第試驗中的導(dǎo)電金屬桿，上下兩端的兩個電磁線圈產(chǎn)生恒定磁常當(dāng)有導(dǎo)電介質(zhì)流過時，則會產(chǎn)生感應(yīng)電壓。管道內(nèi)部的兩個電極測量產(chǎn)生的感應(yīng)電壓。測量管道通過不導(dǎo)電的內(nèi)襯(橡膠，特氟隆等)實現(xiàn)與流體和測量電極的電磁隔離。 </p> <p> 工作特點(diǎn)：①具有雙向測量系統(tǒng);② 傳感器所需的直管段較短，長度為5倍的管道直徑；③ 壓力損失小；④測量不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的影響；⑤主要應(yīng)用于污水處理方面。引壓管路內(nèi)必須始終保持單相流體狀態(tài)。被測流體是氣體時，引壓管路（包括差壓計的壓力腔）內(nèi)全部是氣相；</p><div

超聲波流量計是通過測量流體速度來確定體積流量，對液體應(yīng)該測量它的質(zhì)量流量，儀表測量質(zhì)量流量是通過體積流量乘以人為設(shè)定的密度后得到的，當(dāng)流體溫度變化時，流體密度是變化的，人為設(shè)定密度值，不能保證質(zhì)量流量的準(zhǔn)確度。只能在測量流體速度的同時，又測量了流體密度，才能通過運(yùn)算，得到真實質(zhì)量流量值。 </p> <p> 應(yīng)用概況: </p> <p> 傳播時間法應(yīng)用于清潔、單相液體和氣體。典型應(yīng)用有工廠排放液、:怪液、液化天然氣等;氣體應(yīng)用方面在高壓天然氣領(lǐng)域已有使用良好的經(jīng)驗; </p> <p> 多普勒法適用于異相含量不太高的雙相流體,例如:未處理污水、工廠排放液、臟流程液;通常不適用于非常清潔的液體。流量計有堰槽式流量計，它是通過測量液位來反映流量。江蘇金屬轉(zhuǎn)子流量計廠家直供</p><p style="text-indent:25px">智能電磁流量計在使用時我們要求被測介質(zhì)必須是地電位，一般都是通過管道或法蘭接地；天津插入式巴類流量計價格</p><p> 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，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。特別是夏天，一定做注意這一點(diǎn)。天津插入式巴類流量計價格</p><p
