style="text-indent:25px">電容式液位計(jì)是采用測(cè)量電容的變化來測(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，可通過兩電極間的電容量的變化來測(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。電容液位計(jì)體積小，容易實(shí)現(xiàn)遠(yuǎn)傳和調(diào)節(jié)，適用于具有腐蝕性和高壓的介質(zhì)的液位測(cè)量。杭州投入式液位計(jì)訂購超聲波液位計(jì)適用于哪些場(chǎng)所呢？</p><div

style="text-indent:25px">投入式液位計(jì)工作原理：投入式液位計(jì)的基本工作原理就是靜壓液位測(cè)量。液體介質(zhì)中，某一個(gè)深度產(chǎn)生的壓力就是測(cè)量點(diǎn)以上的介質(zhì)自身的重量所產(chǎn)生的。它與介質(zhì)的密度和當(dāng)?shù)氐闹亓铀俣瘸烧?。通過公式P=ρgh反映了他們之間的比例關(guān)系。其中P=壓力，ρ＝介質(zhì)密度，g＝重力加速度，h＝測(cè)量點(diǎn)的深度。所以投入式液位計(jì)測(cè)量的物理量其實(shí)是壓力，通過投入式液位計(jì)的標(biāo)定單位mH2O 就可以了解。而實(shí)際的液位必須通過知道密度和重力加速度這兩個(gè)參數(shù)后，通過換算獲得。這樣的換算在工業(yè)領(lǐng)域中通常是通過二次儀表或者PLC進(jìn)行的。投入式液位計(jì)主要測(cè)量鹽酸、硫酸、硝酸、氫氟酸、氫氧化鈉、雙氧水等有腐蝕性的液體，或者化工、電鍍廢水。主要應(yīng)用在測(cè)量腐蝕性介質(zhì)，其具有耐腐蝕強(qiáng)，性能穩(wěn)定等優(yōu)點(diǎn)?！　?/p><p style="text-indent:25px">磁致伸縮液位計(jì)優(yōu)缺點(diǎn)：優(yōu)點(diǎn)1.防爆型智能電子線路設(shè)計(jì)可計(jì)算出容積量2.磁致伸縮液位計(jì)可動(dòng)部件為浮子，維護(hù)量極低。應(yīng)用于各類儲(chǔ)罐的液位測(cè)量環(huán)境適應(yīng)性強(qiáng)安裝方便等特點(diǎn)。在短量程測(cè)量上相對(duì)雷達(dá)等液位計(jì)其性價(jià)比極高，功用也很多。顯示屏有電流、溫度、界面顯示。這正是磁致伸縮液位計(jì)能成為當(dāng)今加油站等計(jì)量罐上用得多普遍的產(chǎn)品之一。缺點(diǎn)：1、抗干擾能力略差（一般不建議用在電廠等強(qiáng)電磁輻射的場(chǎng)所）。2、必須是接觸式測(cè)量，但是真正的測(cè)量單元是不與液體接觸的，接觸液體的只是他的保護(hù)管。3、介質(zhì)直接接觸，浮球密封要求要嚴(yán)格，不能測(cè)量粘性介質(zhì)。4、安裝受限。較高的安裝、維護(hù)要求，所以導(dǎo)致市場(chǎng)普及不廣。超聲波液位計(jì)針都采用了Echo-Pipe技術(shù)。</p><div
