液位計根據(jù)浮力原理和磁性耦合作用原理工作的。當被測容器中的液位升降時，液位計主導管中的浮子也隨之升降，浮子內(nèi)的*磁鋼通過磁耦合傳遞到現(xiàn)場指示器，驅(qū)動紅白翻柱轉(zhuǎn)180°，當液位上升時，翻柱由白色轉(zhuǎn)為紅色，當液位下降時翻柱由紅色轉(zhuǎn)為白色，指示器的紅、白界位處為容器內(nèi)介質(zhì)液位的實際高度，從而實現(xiàn)液位的指示。 </p> <p> 適用范圍: </p> <p> 通用型磁性翻柱液位計是zui常用的側(cè)裝式磁翻柱液位計,適用于工作壓力低于2.5 MPa,工作溫度低于200℃的液體介質(zhì)的液位測量。 </p> <p> 通用型磁性翻柱液位計適合容器內(nèi)液體的液位、界位的測量，除現(xiàn)場指示，還可配遠傳變送器、報警（控制）開關，指示功能齊全。指示新穎，讀數(shù)直觀、醒目，觀察指示器的方向可根據(jù)用戶需要改變角度。測量范圍大，不受儲槽高度限制，指示機構(gòu)與被測介質(zhì)完全隔離，因而密封性好，可靠性高，使用安全。結(jié)構(gòu)簡單，安裝方便，維護費用低。黑龍江高溫導播雷達液位計分類液位計根據(jù)浮力原理和磁性耦合作用原理工作的。</p><div

style="text-indent:25px">磁翻板液位計是根據(jù)浮力原理和磁性耦合作用研制而成。這種液位計一般是利用磁致伸縮原理，由波導絲傳遞磁浮子的信號，再由電路處理信號得到液位值。我們在使用的過程中會出現(xiàn)假液位的問題，那么這個問題要怎樣解決呢？下面就來具體介紹一下磁翻板液位計出現(xiàn)假液位問題的解決方法。由于磁翻板液位計測量顯示部分不與介質(zhì)直接接觸，通常情況下，這種液位計具有很高的可靠性。切記不要帶電測量。使用邏輯筆、示波器檢測信號時，用萬用表歐姆擋時。要注意不使探針同時接觸兩個測量引腳，因為這種情況的實質(zhì)是加電的情況下形成短路。</p><p> 我們一般把聲波頻率超過20kHz的聲波稱為超聲波，超聲波是機械波的一種，它的特征是頻率高、波長短、繞射現(xiàn)象小，另外方向性好，能夠成為射線而定向傳播。超聲波在液體、固體中衰減很小，因而穿透能力強，尤其是在對光不透明的固體中，超聲波可穿透幾十米的長度，碰到雜質(zhì)或界面就會有明顯的反射，超聲波測量物位就是利用了它的這一特征。在超聲波檢測技術(shù)中，不管那種超聲波儀器，都必須把電能轉(zhuǎn)換超聲波發(fā)射出去，再接收回來變換成電信號，完成這項功能的裝置就叫超聲波換能器，也稱探頭。如圖所示，將超聲波換能器置于被測液體上方，向下發(fā)射超聲波，超聲波穿過空氣介質(zhì)，在遇到水面時被反射回來，又被換能器所接收并轉(zhuǎn)換為電信號，電子檢測部分檢測到這一信號后將其變成液位信號進行顯示并輸出。由超聲波在介質(zhì)中傳播原理可知，若介質(zhì)壓力、溫度、密度、濕度等條件一定，則超聲波在該介質(zhì)中傳播速度是一個常數(shù)。因此，當測出超聲波由發(fā)射到遇到液面反射被接收所需要的時間，則可換算出超聲波通過的路程，即得到了液位的數(shù)據(jù)。超聲波有盲區(qū)，安裝時必須計算預留出傳感器安裝位置與測量液體之間的距離。導波雷達液位計，化學工業(yè)中的一種液位測量儀表。</p><div

磁翻板液位計具有優(yōu)良的可靠性和抗腐蝕性，在各種塔、罐、槽等容器內(nèi)的介質(zhì)液位檢測上受到客戶一致的好評。當然若想它能給你正常工作，一些技術(shù)也是要掌握的。下面主要給大家介紹下磁翻板液位計的安裝、使用及維護方法，供學習。1.使用前應先用校正磁鋼將零位以下的小球置成紅色，其它球置成白色;2.介質(zhì)內(nèi)不應含有固體雜質(zhì)或磁性物質(zhì)，以免對浮子造成卡阻;3.磁翻板液位計本體周圍不容許有導磁物質(zhì)接近，禁用鐵絲固定，否則會影響磁翻板液位計的正常工作;4.磁翻板液位計安裝必須垂直，磁翻板液位計與容器引管間應裝有球閥，便于檢修和清洗;5.如用戶自行采用伴熱管路時，必須選用非導磁材料，如紫銅管等。伴熱溫度根據(jù)介質(zhì)情況確定;6.打開底法蘭，裝入磁性浮子(注意：重端帶磁性一端向上，不能倒裝);7.調(diào)試時應先打開上部引管閥門，然后緩慢開啟下部閥門，讓介質(zhì)平穩(wěn)進入主導管(運行中應避免介質(zhì)急速沖擊浮子，引起浮子劇列波動，影響顯示準確性)，觀察磁性紅白球翻轉(zhuǎn)是否正常，然后關閉下引管閥門，打開排污閥，讓主導管內(nèi)液位下降，據(jù)此方法操作三次，確屬正常，即可投入運行(腐蝕性等特殊液體除外)。磁翻板液位計清晰的指示出液位的高度,指示器與貯罐完全隔離、安裝方便可靠、性能穩(wěn)定、使用壽命長等優(yōu)點。西安汽油液位計推薦</p><p
