超聲波液位計的工作原理是通過一個可以發(fā)射能量波(一般為脈沖信號)的裝置發(fā)射能量波，能量波遇到障礙物反射，由一個接收裝置接收反射信號。根據(jù)測量能量波運動過程的時間差來確定液(物)位變化情況。由電子裝置對微波信號進行處理，zui終轉(zhuǎn)化成與液位相關(guān)的電信號。一次探頭向被測介質(zhì)表面發(fā)射超聲波脈沖信號，超聲波在傳輸過程中遇到被測介質(zhì)(障礙物)后反射，反射回來的超聲波信號通過電子模塊檢測，通過**軟件加以處理，分析發(fā)射超聲波和回波的時間差，結(jié)合超聲波的傳播速度，可以精確計算出超聲波傳播的路程，寧夏油罐液位計維保，進而可以反映出液位的情況，寧夏油罐液位計維保. 磁浮子液位計和頂裝浮球液位計，寧夏油罐液位計維保，可配置遠傳液位變送器，用以實現(xiàn)液位信號遠傳的數(shù)/模顯示。寧夏油罐液位計維保</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="寧夏油罐液位計維保,液位計"

超聲波液位計的盲區(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的時候盲區(qū)一定是要考慮進去的。在特殊場合，會要求盲區(qū)很小，這個時候可以考慮小盲區(qū)超聲波液位計，其盲區(qū)一般只有4-6cm。但其量程也相對較小，只有。在很多液位測量的領(lǐng)域，因為空間的限制，安裝條件的限制，需要盲區(qū)很小的超聲波液位計。超聲波液位計液位進入盲區(qū)，通常會顯示二次回波對應(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，則液位計會顯示對應(yīng)空間距離為。由于在測量液位時，液面反射良好，因此超聲波液位計發(fā)出的聲脈沖，經(jīng)液面反射后，回波到達換能器(或探頭)表面后又會被重新反射回液面，并被再次反射回換能器并接收，這時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)。寧夏磁翻板液位計特點內(nèi)浮式磁性液位計是一種雙腔液位計，清晰準確地指示出液位的高度。</p><div

在超聲波持續(xù)零液位時，頂部燈亮，輸出電流為22MA。而且隔一段時間后恢復(fù)液位時，故障不能自動解除，需關(guān)電重啟后正常，給客戶帶來不必要的麻煩甚至損失(例如晚上無人值守時)。出現(xiàn)這種故障是安裝附件的選擇問題。超聲波的發(fā)射除了平面頭外，在螺紋這里也是有發(fā)射的。如果持續(xù)的零位，在加上安裝件選用金屬支架。超聲波液位計就會識別到支架部分的信號強度大于平面頭接收的信號強度。而金屬支架部分與發(fā)射波之間處于盲區(qū)距離。所以超聲波處于保護狀態(tài)，故障燈常亮，輸出22MA。解決的辦法就是選用非金屬支架。因為選用非金屬支架后，螺紋處的發(fā)射波能穿透出去，而零點液位的回波信號優(yōu)良會大于螺紋處的回波信號。經(jīng)過上述解釋與實際改進后，故障全部解決，供需雙方皆大歡喜。從而進一步加強了合作。 </p><p> 磁性浮子液位計 </p> <p> 根據(jù)浮力原理和磁性耦合作用研制而成。當(dāng)被測容器中的液位升降時，液位計本體管中的磁性浮子也隨之升降，浮子內(nèi)的長久磁鋼通過磁耦合傳遞到磁翻柱指示器，驅(qū)動紅、白翻柱翻轉(zhuǎn)，當(dāng)液位上升時翻柱由白色轉(zhuǎn)變?yōu)榧t色，當(dāng)液位下降時翻柱由紅色轉(zhuǎn)變?yōu)榘咨甘酒鞯募t白交界處為容器內(nèi)部液位的實際高度，從而實現(xiàn)液位清晰的指示。 </p> <p> 可以做到高密封，防泄漏和適用于高溫、高壓、耐腐蝕的場合。對高溫、高壓、有毒、有害、強腐蝕介質(zhì)更顯其優(yōu)越性。 </p> <p> 與介質(zhì)直接接觸，浮球密封要求要嚴格，不能測量粘性介質(zhì)。磁性材料如退磁易導(dǎo)致液位計不能正常工作 </p> <p> 磁性翻板（柱）式液位計 </p> <p> 翻板容易卡死，造成無法遠傳指示。磁性材料如退磁易導(dǎo)致液位計不能正常工作。液位計投入運行時應(yīng)先打開下引液管閥門讓液體介質(zhì)平穩(wěn)進入主體管，避免液體介質(zhì)帶著浮球組件急速上升。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="寧夏油罐液位計維保,液位計" src="https://tyunfile.71360.com/WaterMark/UploadFile/xalunqian/637329161251162109/5003648.png"></div><p> 靜壓（差壓）式液位計 </p> <p> 由于液柱的靜壓與液位成正比，因此利用壓力表測量基準面上液柱的靜壓就可測得液位。根據(jù)被測介質(zhì)的密度及液體測量范圍計算出壓力或壓差范圍，再選用量程等性能合適的壓力表或差壓表。 </p> <p> 普及范圍廣，容易校準。 </p> <p> 受介質(zhì)密度和溫度影響很大，所以常常精度比較差，而為消除這些影響，需要很多其他測試儀表，結(jié)果搭建一套完善的靜壓測量系統(tǒng)價格很高。 </p> <p> 磁致伸縮式液位計 </p> <p> 探棒上端電子部件產(chǎn)生低壓電流脈沖，開始計時，產(chǎn)生磁場沿磁致伸縮線向下傳播，浮子隨著液位變化沿測量竿上下移動，浮子內(nèi)有磁鐵，也產(chǎn)生磁場，兩個磁場相遇，磁致伸縮線扭曲形成扭應(yīng)力波脈沖，脈沖速度已知，計算脈沖傳播時間即對應(yīng)液位**變化。 </p> <p> 精度較高。適用于油類液體。 </p> <p> 安裝維護復(fù)雜，市場普及率低。（注：脈沖原理，疑也有雷達液位計的缺點）投入式液位計(靜壓液位計/液位變送器/液位傳感器/水位傳感器)是一種測量液位的壓力傳感器。寧夏油罐液位計維保</p><p style="text-indent:25px">液位計安裝必須垂直，以保證浮球組件在主體管內(nèi)上下運動自如。寧夏油罐液位計維保</p><p> 遠傳磁翻板液位計的故障檢查法： </p> <p> 1、替換法：要求有兩臺同型號遠傳磁翻板液位計的儀器或有足夠的備件。將一個好的備品與故障機上的同一元器件進行替換，看故障是否消除。 </p> <p> 2、排除法：通過拔插機內(nèi)一些插件板、器件來判斷故障原因的方法。當(dāng)拔除某一插件板或器件后儀表恢復(fù)正常，就說明故障發(fā)生在那里。 </p> <p> 3、并聯(lián)法：把一塊好的IC芯片安在要檢查的芯片之上，或者把好的元器件與要檢查的元器件并聯(lián)，保持良好接觸，如果故障出自于器件內(nèi)部開路或接觸不佳等原因，則采用這種方法可以排除。 </p> <p> 4、對比法：要求有兩臺同型號的儀表，并有一臺磁性浮子液位計是正常運行的。使用這種方法還要具備必要的設(shè)備。 </p> <p> 5、觀察法：利用視覺、嗅覺、觸覺。某些時候，損壞了的元件會變色、起泡或出現(xiàn)燒焦的斑點;燒壞的器件會產(chǎn)生一些特殊的氣味;短路的芯片會發(fā)燙;用肉眼也能觀察到虛焊或脫焊處。這種方法更適合經(jīng)驗豐富的工作人員。 </p> <p> 6、敲擊手壓法：當(dāng)我們遇到玻璃板液位計運行時好時壞的情況，*好的方法就是應(yīng)用敲擊手壓法。所謂的“敲擊”就是對可能產(chǎn)生故障的部位，通過小橡皮鎯頭或其他敲擊物輕輕敲打插件板或部件，看看是否會引起出錯或停機故障。寧夏油罐液位計維保</p><p
