</p> <p> 五、聚四氟乙烯（PTFE）：1、耐沸騰的鹽酸、硫酸、硝酸、王水、濃堿和各種有機(jī)溶劑；2、耐磨性能好，粘接性能差，溫度要求-80～+180℃；測濃度，甘肅橢圓齒輪流量計(jì)制造商、濃堿強(qiáng)腐蝕性溶液及衛(wèi)生類介質(zhì)，甘肅橢圓齒輪流量計(jì)制造商。渦輪流量計(jì)是速度式流量計(jì)中的主要種類，采用多葉片的轉(zhuǎn)子感受流體平均流速，從而推導(dǎo)出流量或總量的儀表。甘肅橢圓齒輪流量計(jì)制造商</p><div

1、為防止超聲波液位計(jì)信號線受動力線上強(qiáng)電壓、大電流、強(qiáng)電磁的干擾。信號線單獨(dú)走一趟穿線管，遠(yuǎn)離動力線、照明線，分開布線； </p> <p> 2、做好信號屏蔽層，防止信號受干擾； </p> <p> 3、為防止信號線接觸不良，在信號線中間盡量不留接頭，接線端子壓接處不能有任何松動，不然接觸電阻會較大。有接頭的需要用烙鐵焊接信號線接頭，減少故障隱患； </p> <p> 4、為避免超聲波液位計(jì)信號線受潮，信號線走纜溝時(shí)，需架在支架上。信號線尤其接頭處受水浸泡發(fā)潮，會造成儀表信號紊亂； </p> <p> 5、調(diào)節(jié)超聲波液位計(jì)的換能器，表面垂直正對著所測液面，水平度控制在2°； </p> <p> 6、調(diào)好超聲波探頭和液面的距離。過遠(yuǎn)時(shí)，探頭接收的信號太弱，無法和噪聲信號區(qū)分，過近時(shí)，進(jìn)入探頭的盲區(qū)，則無法分辨。氣體渦旋流量計(jì)型號金屬管浮子流量計(jì)無錐管破裂的風(fēng)險(xiǎn)。與玻璃管浮子流量計(jì)相比，使用溫度和壓力范圍寬。</p><div

style="text-indent:25px">橢圓齒輪流量計(jì)(又稱排量流量計(jì)，齒輪流量計(jì))，屬于容積式流量計(jì)一種，在流量儀表中是精度較高的一類。它利用機(jī)械測量元件把流體連續(xù)不斷地分割成單個(gè)已知的體積部分，根據(jù)計(jì)量室逐次、重復(fù)地充滿和排放該體積部分流體的次數(shù)來測量流量體積總量。橢圓齒輪流量計(jì)可以選用不同的材料(鑄鐵、鑄鋼、304不銹鋼、316不銹鋼)制造，適用于化工、石油、醫(yī)藥、電力、冶金和食品等工業(yè)部門的流量計(jì)量工作。橢圓齒輪流量計(jì)是容積式流量計(jì)的一種，用于精密的連續(xù)或間斷的測量管道中液體的流量或瞬時(shí)流量.它特別適合于重油、聚乙烯醇、樹脂等粘度較高介質(zhì)的流量測量。浮子流量計(jì)可用于較低雷諾數(shù)，選用粘度不敏感形狀的浮子，流通環(huán)隙處雷諾數(shù)只要大于40或500。</p><div

當(dāng)超聲波在不均勻流體中傳送時(shí)，聲波會產(chǎn)生散射。流超聲流量計(jì)體與發(fā)送器間有相對運(yùn)動時(shí)，發(fā)送的聲波信號和被流體散射后接收到的信號之間會產(chǎn)生多普勒頻移。多普勒頻移與流體流速成正比。被測流體的區(qū)域位于發(fā)射波束與接收到的散射波束的交叉之處。要求波束很窄，使兩波束的夾角θ不致受到波束寬度影響。也可只采用一個(gè)變換器既作為發(fā)送器又作為jieshouqi，這種方式稱為單通道式。在單通道多普勒血液流量計(jì)中，發(fā)送器間隔地發(fā)送聲脈沖信號，在兩個(gè)聲脈沖間隔的時(shí)間中，接收從血管壁和血管內(nèi)紅血球反射回來的聲脈沖信號。采用控制線路選擇給定距離處的紅血球反射信號,通過比較后得到多普勒頻移,它與血液流速成正比。在已知血管橫截面時(shí)可得到血液流量。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(jì)也得到了普遍應(yīng)用。甘肅橢圓齒輪流量計(jì)制造商</p><p

液體流量計(jì)的正確使用步驟:在使用壓力傳感器前，對其進(jìn)行性能測試。將它接上透明的水管，用水柱高坐壓力，用高靈敏度數(shù)字萬用表測量電壓，不足之處是在安裝時(shí)需要一定直管段，且普通型對于振動和高溫沒有很好的解決辦法。渦街有壓電式和電容式，后者在耐溫和耐振動方面有優(yōu)勢，但價(jià)格較貴，一般用于過熱蒸汽的測量。只要能傳播聲音的流體均可以用液體流量計(jì);超聲波流量計(jì)可以測量高粘度液體、非導(dǎo)電性液體或氣體的流量，其測量流速的原理是:超聲波在流體中的傳播速度會隨被測流體流速而變化。容積式流量計(jì)容積式流量計(jì)是通過測定殼體和轉(zhuǎn)子之間形成的計(jì)量容積來測量流體的體積流量。根據(jù)轉(zhuǎn)子的結(jié)構(gòu)形式，容積式流量計(jì)有腰輪式，刮板式、橢圓齒輪式等。隨著工業(yè)發(fā)展對流量計(jì)量要求的不斷提高，液體流量計(jì)在工業(yè)測量中的地位已經(jīng)部分地被先進(jìn)的、高精度的、便利的流量儀表所取代。液體流量計(jì)基于法拉第電磁感應(yīng)原理研制出的一種測量導(dǎo)電液體體積流量的儀表。又稱轉(zhuǎn)子流量計(jì)，是變面積式流量計(jì)的一種，在一根由下向上擴(kuò)大的垂直錐管中，圓形橫截面的浮子的重力是由液體動力承受的。浮子可以在錐管內(nèi)自由地上升和下降。在流速和浮力作用下上下運(yùn)動與浮子重量平衡后。甘肅橢圓齒輪流量計(jì)制造商</p><p
