應(yīng)用范圍：液態(tài)瀝青、聚合反應(yīng)堆容器（高壓）、反應(yīng)堆容器（真空）、熔融態(tài)玻璃、黑色及有色金屬、合金聚笨已烯，尼龍、聚氯已稀等芯塊、滑石粉或石灰粉、礦石、放礦溜井里的廢石、濕或干木屑；采礦，化工；制藥，造紙，塑料，油氣等高風(fēng)險區(qū)域。 </p> <p> 使用限制：有霧的工況下使用精度很差或者使用不了 </p> <p> 精度等級：液體:≤2 cm/固體:≤4 cm </p> <p> 優(yōu)點(diǎn)：測量光束發(fā)散角小，方向性好；量程大，測距遠(yuǎn)、盲點(diǎn)??；不受介質(zhì)溫度影響；非插入式測量，非接觸測量；測量速度快，適合變化快的液位及料位測量；操作簡單，可編程測量；測量精確、高精度適合高要求項目；分辨率高出一般表十倍；波束角小，適合長距離定位，避免障礙物。 </p>

差壓式超聲波液位計工作原理：差壓式超聲波液位計是根據(jù)安裝于管道中流量檢測件產(chǎn)生的差壓,已知的流體條件和檢測件與管道的幾何尺寸來計算流量的儀表。差壓式超聲波液位計由一次裝置（檢測件）和二次裝置（差壓轉(zhuǎn)換和流量顯示儀表）組成。通常以檢測件形式對差壓式超聲波液位計分類,如孔板超聲波液位計、文丘里超聲波液位計、均速管超聲波液位計等。二次裝置為各種機(jī)械、電子、機(jī)電一體式差壓計,差壓變送器及流量顯示儀表。它已發(fā)展為三化（系列化、通用化及標(biāo)準(zhǔn)化）程度很高的、種類規(guī)格龐雜的一大類儀表,它既可測量流量參數(shù),也可測量其它參數(shù)（如壓力、物位、密度等）。差壓式超聲波液位計的檢測件按其作用原理可分為:節(jié)流裝置、水力阻力式、離心式、動壓頭式、動壓頭增益式及射流式幾大類。檢測件又可按其標(biāo)準(zhǔn)化程度分為二大類:標(biāo)準(zhǔn)的和非標(biāo)準(zhǔn)的。所謂標(biāo)準(zhǔn)檢測件是只要按照標(biāo)準(zhǔn)文件設(shè)計、制造、安裝和使用,無須經(jīng)實(shí)流標(biāo)定即可確定其流量值和估算測量誤差。非標(biāo)準(zhǔn)檢測件是成熟程度較差的,尚未列入國際標(biāo)準(zhǔn)中的檢測件。差壓式超聲波液位計是一類應(yīng)用的超聲波液位計,在各類流量儀表中其使用量占居**。近年來,由于各種新型超聲波液位計的問世,它的使用量百分?jǐn)?shù)逐漸下降。連云港導(dǎo)波雷達(dá)液位計磁翻板液位計的兼容性高，一直以來在工業(yè)生產(chǎn)中都得到了大量的應(yīng)用，是槽、罐等容器液位測量中的理想之選。</p><div

導(dǎo)波雷達(dá)液位計與普通雷達(dá)液位計的比較普通雷達(dá)為非接觸式測量，導(dǎo)波雷達(dá)為接觸式測量，這樣就意味導(dǎo)波雷達(dá)更需考慮介質(zhì)的腐蝕性和粘附性，而且過長的導(dǎo)波雷達(dá)安裝和維護(hù)更加困難。普通雷達(dá)可以互換使用，而導(dǎo)波雷達(dá)由于導(dǎo)波桿（纜）長度根據(jù)原工況固定，一般不能互換使用，受此影響導(dǎo)波雷達(dá)的選型要比普通雷達(dá)麻煩。測量固體物料時，導(dǎo)波雷達(dá)還要考慮導(dǎo)波桿（纜）的受力情況，也是由于受力的原因一般用導(dǎo)波雷達(dá)的測量距離不會很長，而普通雷達(dá)在30、40m的罐體上應(yīng)用比較常見，甚至可測到60m。另外一般的導(dǎo)波雷達(dá)還有底部探測功能，可以根據(jù)底部回波信號能測量值加以修正，使信號更為穩(wěn)定準(zhǔn)確。不過在一些特殊工況導(dǎo)波雷達(dá)有明顯的優(yōu)勢，如罐內(nèi)有攪拌，介質(zhì)波動大，這樣的工況用底部固定的導(dǎo)波雷達(dá)測量值要比變通雷達(dá)穩(wěn)定；還有小罐體內(nèi)的物位測量，由于安裝測量空間?。ɑ蚬迌?nèi)干擾物較多），一般普通雷達(dá)不適用，這時導(dǎo)波雷達(dá)的優(yōu)勢就顯現(xiàn)出來了；再有是低介電常數(shù)的工況，無論雷達(dá)還是導(dǎo)波雷達(dá)測量原理都是基于介質(zhì)介電常數(shù)差別，由于普通雷達(dá)的發(fā)射的波是發(fā)散的，當(dāng)介質(zhì)介電常數(shù)過低時，信號太弱測量不穩(wěn)定，而導(dǎo)波雷達(dá)波是沿導(dǎo)波桿傳播信號相對穩(wěn)定。 </p><p> 磁致伸縮液位計 </p> <p> 工作原理：磁致伸縮計的傳感器工作時，傳感器的電路部分將在波導(dǎo)絲上激勵出脈沖電流，該電流沿波導(dǎo)絲傳播時會在波導(dǎo)絲的周圍產(chǎn)生脈沖電流磁場。在磁致伸縮液位計的傳感器測桿外配有一浮子，此浮子可以沿測桿隨液位的變化而上下移動。在浮在內(nèi)部有一組長久磁環(huán)。當(dāng)脈沖電流磁場與浮子產(chǎn)生的磁環(huán)磁場相遇時，浮子周圍的磁場發(fā)生改變從而使得由磁致伸縮材料做成的波導(dǎo)絲在浮子所在的位置產(chǎn)生一個扭轉(zhuǎn)波脈沖，這個脈沖以固定的速度沿波導(dǎo)絲傳回并由檢出機(jī)構(gòu)檢出。通過測量脈沖電流與扭轉(zhuǎn)波的時間差可以精確地確定浮子所在的位，即液面的位置。

原理：對于不可壓縮的液體，液位高度與液體的靜壓力成正比，所以，測出液體的靜壓力，即可知道液位高度?！静顗鹤兯推?、單法蘭差壓變送器、雙法蘭差壓變送器、（可測壓力容器的液位，但不能用于高溫測量）投入式液位計（可測常壓容器的液位）】。 </p> <p> 電容式液位計 </p> <p> 原理：在平行板電容器之間充以不同介質(zhì)時，其電容量的大小是不同的。可以用測量容器的變化來檢測液位或兩種不同介質(zhì)的液位分界面。 </p> <p> 雷達(dá)式液位汁 </p> <p> 原理：利用超高頻電磁波經(jīng)天線向被測容器的液面發(fā)射，當(dāng)電磁波遇到液面后反射回來，通過測出發(fā)射波和反射波的時間差，計算出液面高度。這種液位計為非接觸式液位計，可測壓力容器的液位。磁翻板液位計測量通道是段光滑直管，不會阻塞，適用于測量含固體顆粒的液固二相液體，如泥漿、污水等；徐州導(dǎo)波雷達(dá)液位計批發(fā)采購</p><p style="text-indent:25px">在形形**的傳感器大軍中，液位計占有重要的地位，它是我們生產(chǎn)生活的安全保障。徐州導(dǎo)波雷達(dá)液位計批發(fā)采購</p><p> 浮球液位計 </p> <p> 1、工作原理 </p> <p> 浮球液位計結(jié)構(gòu)主要是基于浮力和靜磁場原理設(shè)計生產(chǎn)的。帶有磁體的浮球在被測介質(zhì)中的位置受浮力作用影響，液位的變化導(dǎo)致磁性浮子位置的變化。浮球中的磁體和傳感器（磁簧開關(guān)）作用，使串連入電路的元件（如定值電阻）的數(shù)量發(fā)生變化，進(jìn)而使儀表電路系統(tǒng)的電學(xué)量發(fā)生改變。也就是使磁性浮子位置的變化引起電學(xué)量的變化。通過測量電學(xué)量的變化來反映容器內(nèi)液位的情況。 </p> <p> 2、特點(diǎn)及適用場合 </p> <p> 2.1結(jié)構(gòu)簡單、使用方便 </p> <p> 2.2性能穩(wěn)定、使用壽命長、便于安裝維護(hù) 幾乎可以適用于各種工業(yè)自動化過程控制中的液位測量和控制，可以運(yùn)用于石油加工、食品加工、化工、水處理、制藥、電力、造紙、冶金、船舶和鍋爐等領(lǐng)域中的液位測量、控制與檢測。徐州導(dǎo)波雷達(dá)液位計批發(fā)采購</p></p><br /><p>文章來源地址:
