style="text-indent:25px">什么是超聲波液位計(jì)的工作盲區(qū)?當(dāng)物體離眼睛較近且角度一定的時(shí)候，反而看不清楚了或者看不見(jiàn)，在這一范圍就叫做盲區(qū)。超聲波液位計(jì)的盲區(qū)也如同人眼的盲區(qū)一樣。超聲波液位計(jì)的工作原理，是根據(jù)超聲波的發(fā)射和接收來(lái)實(shí)現(xiàn)的。超聲波在空氣中傳輸?shù)乃俣仁且欢ǖ?，超聲波發(fā)射出去，然后接收液面或物面反射回來(lái)的波，從發(fā)射開(kāi)始計(jì)時(shí)，到接收到回波結(jié)束。超聲波在空氣中傳輸?shù)臅r(shí)間就定了。因?yàn)槭且粋€(gè)來(lái)回，那實(shí)際距離就是距離的一半。池子的深度或罐體的高度是一定的。那實(shí)際液位就是池子的深度減去超聲波液位計(jì)測(cè)量的距離，就是液位或物位的高度了。由此，就實(shí)現(xiàn)了超聲波測(cè)量液位或者物位了。導(dǎo)波雷達(dá)物位計(jì)只有物料處于頂部盲區(qū)和底部盲區(qū)之間時(shí)，才能保證罐內(nèi)物位的可靠測(cè)量。</p><div

采用測(cè)量電容的變化來(lái)測(cè)量液面的高低的。它是一根金屬棒插入盛液容器內(nèi)，金屬棒作為電容的一個(gè)極，容器壁作為電容的另一極。兩電極間的介質(zhì)即為液體及其上面的氣體。由于液體的介電常數(shù)ε1和液面上的介電常數(shù)ε2不同，比如：ε1》ε2，則當(dāng)液位升高時(shí)，兩電極間總的介電常數(shù)值隨之加大因而電容量增大。反之當(dāng)液位下降，ε值減小，電容量也減小。所以，可通過(guò)兩電極間的電容量的變化來(lái)測(cè)量液位的高低。電容液位計(jì)的靈敏度主要取決于兩種介電常數(shù)的差值，而且，只有ε1和ε2的恒定才能保證液位測(cè)量準(zhǔn)確，因被測(cè)介質(zhì)具有導(dǎo)電性，所以金屬棒電極都有絕緣層覆蓋。 </p> <p> 傳感器無(wú)機(jī)械可動(dòng)部分，結(jié)構(gòu)簡(jiǎn)單、可靠；精zhun度高；檢測(cè)端消耗電能小，動(dòng)態(tài)響應(yīng)快；維護(hù)方便，壽命長(zhǎng)。被測(cè)介質(zhì)需為導(dǎo)電率不低于10－3S／M的非結(jié)晶導(dǎo)電液體。 </p> <p> 被測(cè)液體的介電常數(shù)不穩(wěn)定會(huì)引起誤差。電容式液位計(jì)一般用于調(diào)節(jié)池、清水池測(cè)量。（注：液化氣是否會(huì)對(duì)測(cè)量造成影響未知待確定）浮球液位計(jì)能對(duì)開(kāi)口、密閉容器或地下池槽里的介質(zhì)液位在儀表控制室內(nèi)進(jìn)行顯示、報(bào)警和控制。寧夏硫酸儲(chǔ)罐液位計(jì)用途</p><p style="text-indent:25px">當(dāng)液位計(jì)投入到被測(cè)液體中某一深度時(shí)，傳感器迎液面受到的壓力公式為:Ρ = ρ .g.H + Po。油庫(kù)液位計(jì)哪個(gè)好</p><p> 超聲波液位計(jì)的盲區(qū)，根據(jù)量程的不同，盲區(qū)也不同。量程小，則盲區(qū)小，量程大，則盲區(qū)大。但一般都在30cm-50cm之間。所以一般在安裝超聲波液位計(jì)的時(shí)候盲區(qū)一定是要考慮進(jìn)去的。在特殊場(chǎng)合，會(huì)要求盲區(qū)很小，這個(gè)時(shí)候可以考慮小盲區(qū)超聲波液位計(jì)，其盲區(qū)一般只有4-6cm。但其量程也相對(duì)較小，只有。在很多液位測(cè)量的領(lǐng)域，因?yàn)榭臻g的限制，安裝條件的限制，需要盲區(qū)很小的超聲波液位計(jì)。超聲波液位計(jì)液位進(jìn)入盲區(qū)，通常會(huì)顯示二次回波對(duì)應(yīng)的液位位置。舉例而言，如果盲區(qū)是，液面至換能器(或探頭)表面的距離是，則液位計(jì)會(huì)顯示對(duì)應(yīng)空間距離為。由于在測(cè)量液位時(shí)，液面反射良好，因此超聲波液位計(jì)發(fā)出的聲脈沖，經(jīng)液面反射后，回波到達(dá)換能器(或探頭)表面后又會(huì)被重新反射回液面，并被再次反射回?fù)Q能器并接收，這時(shí)的回波即為二次回波。如果反射條件良好，還可能收到多次回波(多次往返的回波)。油庫(kù)液位計(jì)哪個(gè)好</p><p
