alt="湖北液體渦輪流量計(jì)源頭直供廠家,流量計(jì)" src="https://tyunfile.71360.com/UploadFile/jszhck/637312837271718750/6710757.png"></div><p> 智能型電磁流量計(jì)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(gè)方面： </p> <p> 一、使用場(chǎng)所的原因 </p> <p> 使用場(chǎng)所如果不太好，比如現(xiàn)場(chǎng)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(jì)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(jiān)著的管子上，這些都會(huì)使智能電磁流量計(jì)使用出現(xiàn)問題。 </p> <p> 三、測(cè)量介質(zhì)的原因 </p> <p> 如果所測(cè)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(cè)量介質(zhì)里面有許多氣泡，它就會(huì)地影響測(cè)量信號(hào)輸出地穩(wěn)定性。 </p> <p> <br /> </p> <p> 四、長(zhǎng)期使用了的智能電磁流量計(jì)的內(nèi)管里會(huì)積污垢，這樣也會(huì)影響電磁流量計(jì)的測(cè)量效果。 </p> <p> 五、電磁流量計(jì)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)。 </p><p> 超聲波流量計(jì)是通過測(cè)量流體速度來確定體積流量，對(duì)液體應(yīng)該測(cè)量它的質(zhì)量流量，儀表測(cè)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(shí)，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(cè)量流體速度的同時(shí)，又測(cè)量了流體密度，才能通過運(yùn)算，得到真實(shí)質(zhì)量流量值。 </p> <p> 應(yīng)用概況: </p> <p> 傳播時(shí)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(yàn); </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。引壓管路內(nèi)必須始終保持單相流體狀態(tài)。被測(cè)流體是氣體時(shí)，引壓管路（包括差壓計(jì)的壓力腔）內(nèi)全部是氣相；</p><div style="width:100%;text-align: center;"><img

<p> （1）抗振性能差。外來振動(dòng)會(huì)使渦街流量計(jì)產(chǎn)生測(cè)量誤差，甚至不能正常工作。通道流體高流速?zèng)_擊會(huì)使渦街發(fā)生體的懸臂產(chǎn)生附加振動(dòng)，使測(cè)量精度降低。大管徑影響更為明顯。 </p> <p> （2）對(duì)測(cè)量臟污介質(zhì)適應(yīng)性差。渦街流量計(jì)的發(fā)生體極易被介質(zhì)臟污或被污物纏繞，改變幾何體尺寸，對(duì)測(cè)量精度造成極大影響。 </p> <p> <span style="font-size:12px;">（3）直管段要求高。**指出，渦街流量計(jì)直管段一定要保證前 40D 后
