工作原理：伺服液位計的測量是基于浮力平衡原理而設(shè)計的。固定在驅(qū)動電機(jī)的內(nèi)磁鐵輪與經(jīng)過精密加匿報輪鼓（即外磁鐵輪）之間完成磁偶合。使得輪鼓和驅(qū)動電機(jī)形成同步旋轉(zhuǎn)，而內(nèi)磁與輪鼓（外磁鐵輪）之間被外殼完全隔離，從而使得被測液體腔與與電氣部分完全隔離而滿足防爆要求，將測量鋼絲均勻整齊的排列在輪鼓上。浮子通過測量鋼絲被送到罐內(nèi)。當(dāng)罐內(nèi)液位（界面或比重）變化時，由于浮子的重量隨變化的液位而改變，浮子變化的重量使得輪鼓（外磁鐵輪）與內(nèi)磁鐵輪之間形成耦合差。將該信號送入微處理器進(jìn)行計算判斷后，給伺服電機(jī)發(fā)出控制指令，使得罐內(nèi)浮子始終隨液位高度的變化而變化。從而即可以通過測量輪鼓的旋轉(zhuǎn)角度，計算后得到液位的高度值。 </p> <p> 應(yīng)用范圍：石**業(yè)、化工行業(yè)、食品行業(yè) </p> <p> 使用限制：主要應(yīng)用在(無腐蝕性的液體）輕油品的高精度測量中。 </p> <p> 精度等級：士0，浙江雷達(dá)液位計供貨商.3mm/±1mm </p> <p> 優(yōu)點：位測精度正負(fù)1毫米；液體表面氣泡及乳化層不影響測量精度；罐底沉積物不影響測量精度；可選用各種罐型的測量；同時測量液位、界面、比重及罐內(nèi)溫度，浙江雷達(dá)液位計供貨商。 </p> <p> 缺點：接觸式液位計，浙江雷達(dá)液位計供貨商、售價較高；安裝調(diào)試比較麻煩。雷達(dá)液位計的天線發(fā)射出電磁波，這些波經(jīng)被測對象表面反射后，再被天線接收；浙江雷達(dá)液位計供貨商</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

應(yīng)用范圍：高溫磁翻板液位計適合在高溫高壓的液體里面進(jìn)行測量的，液位介質(zhì)較高溫度可達(dá)450度。被廣泛應(yīng)用到石油化工、食品、環(huán)保冶金等行業(yè)中。由于介質(zhì)完全密封在液位計中，所以對于易燃、易爆、有毒、腐蝕的液體非常適用。 </p> <p> 使用限制：測量介質(zhì)無雜質(zhì)或者很少的雜質(zhì)；不粘稠，不結(jié)晶。 </p> <p> 精度等級：精度在±5.0mm－±10mm之間。 </p> <p> 優(yōu)點：1、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，如紙漿、泥漿、污水等；2、不產(chǎn)生流量檢測所造成的壓力損失，節(jié)能效果好；3、所測得體積流量實際不不受液體密度、粘度、溫度、壓力和電導(dǎo)率變化的明顯影響；4、流量范圍大、口徑范圍寬；能夠快速、直觀地讀數(shù)；價格較低；可實現(xiàn) 遠(yuǎn)傳和調(diào)節(jié)；體積較小，容易實現(xiàn)遠(yuǎn)傳和調(diào)節(jié)；適用于具有腐蝕性和高壓介質(zhì)。 </p> <p> 缺點：精度較低，測量精度一般在±5.0mm－±10mm之間；安裝復(fù)雜；有一定量程限制；不能測量氣體、蒸汽和含有較大氣泡的液體；不能用于較高溫度；大量磁翻板液體計運輸不方便，且安裝體積較大。 </p> <p> <br /> 山東導(dǎo)波雷達(dá)液位計生產(chǎn)廠家雷達(dá)液位計采用發(fā)射—反射—接收的工作模式。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江雷達(dá)液位計供貨商,位計" src="https://tyunfile.71360.com/UploadFile/jszhck/637412295631611826/4039069.png"></div><p> 雷達(dá)液位計（導(dǎo)波雷達(dá)液位計） </p> <p> 工作原理：雷達(dá)液位計采用發(fā)射—反射—接收的工作模式。雷達(dá)液位計的天線發(fā)射出電磁波，這些波經(jīng)被測對象表面反射后，再被天線接收，電磁波從發(fā)射到接收的時間與到液面的距離成正比，關(guān)系式如下：D=CT/2（D：雷達(dá)液位計到液面的距離C：光速T：電磁波運行時間）雷達(dá)液位計記錄脈沖波經(jīng)歷的時間，而電磁波的傳輸速度為常數(shù)，則可算出液面到雷達(dá)天線的距離，從而知道液面的液位。 </p> <p> 優(yōu)點：不需要傳輸媒介，不受大氣、蒸氣、槽內(nèi)揮發(fā)霧影響的特點，能用于揮發(fā)介質(zhì)的液位測量。采用非接觸式測量，不受槽內(nèi)液體的密度、濃度等物理特性的影響。 </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。 </p> <p> 應(yīng)用范圍：中石油及中石化成品油流通行業(yè)。 </p> <p> 使用限制：溫度過高、量程過大、粘度過大的儲罐 </p> <p> 精度等級：±0.01%FS/±0.3mm 差壓式液位汁是利用容器內(nèi)液位改變時，由液柱產(chǎn)生的靜壓也相應(yīng)變化的原理而工作的；</p><div style="width:100%;text-align:

渦輪超聲波液位計,是速度式超聲波液位計中的主要種類,它采用多葉片的轉(zhuǎn)子（渦輪）感受流體平均流速,從而且推導(dǎo)出流量或總量的儀表。 </p> <p> 一般它由傳感器和顯示儀兩部分組成,也可做成整體式。渦輪超聲波液位計和容積式超聲波液位計、科里奧利質(zhì)量超聲波液位計稱為超聲波液位計中三類重復(fù)性、精度比較好的產(chǎn)品,作為**類型超聲波液位計之一,其產(chǎn)品已發(fā)展為多品種、多系列批量生產(chǎn)的規(guī)模。 </p> <p> 優(yōu)點: 高精度,在所有超聲波液位計中,屬于精確的超聲波液位計; </p> <p> 重復(fù)性好; </p> <p> 元零點漂移,抗干擾能力好; </p> <p> 范圍度寬; </p> <p> 結(jié)構(gòu)緊湊。 </p> <p> 缺點: 不能長期保持校準(zhǔn)特性; </p> <p> 流體物性對流量特性有較大影響。 </p> <p> 應(yīng)用概況:渦輪超聲波液位計在以下一些測量對象獲得廣泛應(yīng)用:石油、有機(jī)液體、無機(jī)液、液化氣、天然氣和低溫流體統(tǒng)在歐洲和美國,渦輪超聲波液位計在用量上是*次于孔板超聲波液位計的天然計量儀表,*荷蘭在天然氣管線上就采用了2600多臺各種尺寸,壓力從0.8~6.5MPa的氣體渦輪超聲波液位計,它們已成為優(yōu)良的天然氣計量儀表。磁翻板液位計的結(jié)構(gòu)由浮筒（主導(dǎo)管）、磁浮子、磁翻板（磁翻柱）、指示器、排污閥、連接法蘭等組成。浙江雷達(dá)液位計供貨商</p><p style="text-indent:25px">當(dāng)介質(zhì)內(nèi)出現(xiàn)真空啊、蒸汽含量過高、以及液面泡沫等情況時是不能選用超聲波液位計的；浙江雷達(dá)液位計供貨商</p><p> 浮筒液位（界面）計 </p> <p> 工作原理：浮筒液位計是根據(jù)阿基米德定律和磁耦合原理設(shè)計而成的液位測量儀表，儀表可用來測量液位、界位和密度，負(fù)責(zé)上下限報警信號輸出。**于測量壓力容器內(nèi)液位，同四個基本部分組成：浮筒、彈簧、磁鋼室和指示器。 </p> <p> 應(yīng)用范圍：用于石油、化工、冶金、電力、醫(yī)藥、食品、造紙等行業(yè)液體的測量與過程控制。 </p> <p> 使用限制：一般的液態(tài)介質(zhì)都是可以測量的，但局限于小量程，大量程的浮筒液位計運輸、安裝非常不方便，其他的費用非常高，所以特別大量程的現(xiàn)場不建議使用浮筒液位計，超過5M基本上就沒有人做了 </p> <p> 精度等級：±0.5%FS </p> <p> 優(yōu)點：測量精度高； </p> <p> 智能化：利用HART通訊協(xié)議的該儀表使用戶容易存取過程操作的信息； </p> <p> 高靈敏：能反應(yīng)過程的小變化： </p> <p> 扭力管采用優(yōu)化的熱處理工藝，具有優(yōu)良的溫度和時間穩(wěn)定性； </p> <p> 結(jié)構(gòu)堅固，耐腐蝕； </p> <p> 應(yīng)用面廣，適用性強(qiáng)。 </p> <p> 缺點：安裝，運輸不方便，如果液罐過高則不適用。浙江雷達(dá)液位計供貨商</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/3063978.html</p></div></div></div></div></div><div id="tlnxlbh" class="page-right twoColRt"><div id="zr7p7zv"
