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行計算判斷后，給伺服電機發(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0.3mm/±1mm </p> <p> 優(yōu)點：位測精度正負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，泰州導(dǎo)波雷達液位計批發(fā)采購、比重及罐內(nèi)溫度。 </p> <p> 缺點：接觸式液位計，泰州導(dǎo)波雷達液位計批發(fā)采購，泰州導(dǎo)波雷達液位計批發(fā)采購、售價較高；安裝調(diào)試比較麻煩。孔板式超聲波液位計結(jié)構(gòu)牢固,性能穩(wěn)定可靠,使用壽命長;泰州導(dǎo)波雷達液位計批發(fā)采購</p><div style="width:100%;text-align: center;"><img

</p> <p> 導(dǎo)波雷達液位計的基礎(chǔ)是電磁波的時域反射原理，微波脈沖不是通過空間傳播，而是通過金屬導(dǎo)波桿傳播，當(dāng)遇到與液面的接觸面時，由于波導(dǎo)體在氣體和液體中的導(dǎo)電性能不同，使波導(dǎo)體的阻抗發(fā)生驟然變化，從而產(chǎn)生一個液位原始脈沖，同時在波導(dǎo)體頂部具有一個預(yù)先設(shè)定的阻抗，該阻抗產(chǎn)生一個可靠的基本脈沖，雷達液位計檢測到液面脈沖后與基本脈沖進行比較，從而計算出液面高度。 </p> <p> 2、特點及適用場合 </p> <p> 2.1測量不受罐體形狀的影響 </p> <p> 2.2不受介電常數(shù)、溫度、壓力和密度的影響 </p> <p> 2.3不受物位表面波動、粉塵、蒸汽和泡沫的影響 </p> <p> 2.4測量長度可以靈活變更，無須標(biāo)定 </p> <p> 2.5測量結(jié)果具有高精度、可重復(fù)性、**辯率 </p> <p> 2.6 適用的壓力范圍高達40bar 導(dǎo)波雷達液位計應(yīng)用于水液儲罐、酸堿儲罐、漿料儲罐、固體顆粒、小型儲油罐。各類導(dǎo)電、非導(dǎo)電介質(zhì)、腐蝕性介質(zhì)。江西雷達液位計廠家磁翻板液位計由于浮筒會吸附介質(zhì)中的污垢，因此磁翻板液位計每年不定期清洗浮筒內(nèi)雜質(zhì)，每天至少清洗一次。</p><div

</p> <p> 超聲波液位開關(guān) </p> <p> 優(yōu)點：超聲波液位計是非接觸測量方式，±0.2%精度，1-25米量程，優(yōu)異的聚焦：5度聲束角，多種傳感器材質(zhì)，內(nèi)置全量程溫度補償。超聲波液位計測量有腐蝕（酸、堿）的介質(zhì)、有污染的場合，或易產(chǎn)生粘附物的物質(zhì)。適合于那些無法用物理方式接觸的液體。 </p> <p> 缺點：1：與被測介質(zhì)粘度有關(guān)，被測介質(zhì)粘度較大時不鞥測量； </p> <p> 2：受溫度影響，當(dāng)溫度高時，傳播速度回發(fā)生變化，儀表反應(yīng)遲緩，會延遲報警。 </p><p> Y射線液位計 </p> <p> 工作原理：該儀表基于Y射線穿透物質(zhì)層粒子被吸收的工作原理。 </p> <p> 應(yīng)用范圍：特別適用于存在淋雨、液滴及液面波動的高壓容器內(nèi)的液位測量。適用于高溫、高壓、腐蝕性強、毒性大、煙霧大等一般儀表不能或難以使用的復(fù)雜、惡劣工況下位的測量。 </p> <p> 使用限制：一般工況都不適用，對人身體有傷害，一般用在雨淋的反應(yīng)塔 </p> <p> 精度等級：±（3-5)%標(biāo)定量程 </p> <p> 優(yōu)點：非接觸連續(xù)測量； </p> <p> 安裝簡易（不需要發(fā)動設(shè)備或是在設(shè)備上開孔） </p> <p> 缺點：重大污染源；造價使用成本高；測量精度低（正負3%）磁翻板液位計體積較小，容易實現(xiàn)遠傳和調(diào)節(jié)；適用于具有腐蝕性和高壓介質(zhì)。</p><div style="width:100%;text-align:

雷達液位計（導(dǎo)波雷達液位計） </p> <p> 工作原理：雷達液位計采用發(fā)射—反射—接收的工作模式。雷達液位計的天線發(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：雷達液位計到液面的距離C：光速T：電磁波運行時間）雷達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。磁翻板液位計安裝位置應(yīng)避開加液口，防止液位計護導(dǎo)管或浮球受到?jīng)_擊；河北80HZ調(diào)頻雷達料位計多少錢</p><p

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，如圖1所示。差壓變送器的一端接液相，另一端接氣相時根據(jù)流體靜力學(xué)原理，我們知道，變送器正壓室受到的壓力為：Pl=P氣十ρgH。式中H：液位高度;ρ：介質(zhì)密度;g：重力加速度;P氣：氣相壓力。圖1差壓變送器測量液位計示意圖差壓變送器負壓室壓力P2=P氣，則正負壓室的差壓為：ΔP=P1-P2。通常，被測介質(zhì)的密度是已知的。因此，測得差壓值就能知道液位高度。 </p> <p> 2、特點及適用場合 </p> <p> 2.1可做到高密封、防泄漏 </p> <p> 2.2高溫、高壓、高粘度、強腐蝕性條件下安全可靠地測量液位 </p> <p> 2.3全過程測量無盲區(qū)、顯示醒目，讀數(shù)直觀，并且測量范圍大配上液位報警、控制開關(guān)，可實現(xiàn)液位或界位的上下限報警和控制。安裝方便，容易實現(xiàn)遠傳和自動調(diào)節(jié)，工業(yè)上應(yīng)用較多。為比較成熟的液位測量儀表，測量精度較高，維護量少。單法蘭（單引壓線）液位計一般用于敞口或常壓容器，密閉帶壓設(shè)備應(yīng)選用雙法蘭（雙引壓線）液位計。泰州導(dǎo)波雷達液位計批發(fā)采購</p></p><br
