國產(chǎn)超聲波液位計包含多項技術，具有安全、清潔、精度高、壽命長、穩(wěn)定可靠、安裝維護方便等特點，適用酸、堿、鹽、防腐、高溫等各種領域。儀表可通過4~20mA或RS485連接到顯示表或各種DCS系統(tǒng)中，為工業(yè)的自動化運行，提供實時的液位數(shù)據(jù)。 </p> <p> 國產(chǎn)超聲波液位計工作原理： </p> <p> 國產(chǎn)超聲波液位計是基于超聲波在礦漿這類均勻懸浮液中傳播時，其振幅隨被測礦漿中固體量的多少及粒子大小變化而變化的超聲衰減測量。只要測出超聲波穿過被測礦漿時的衰減量就可知道被測礦漿的濃度。在一定條件下，當?shù)V漿中粒子很小時，粘滯吸收衰減起主要作用；當顆粒很大時，散射衰減起主要作用。 </p> <p> 國產(chǎn)超聲波液位計特點 </p> <p> ● zui大量程可達40m 固體料位測量可達25m。 </p> <p> ● zui小分辨率1mm。 </p> <p> ● LCD/LED大顯示屏。 </p> <p> ● 智能信號處理技術。 </p> <p> ● 全塑料防腐外殼：防護等級IP67。 </p> <p> ● 的換能器結構：小量程物位計法蘭安裝時，對法蘭接管長度無要求。 </p> <p> ● 簡單的按鍵設定參數(shù)：無需等待容器排空或加滿，無需附加的遙控器。 </p> <p> ● 靈活的安裝方式：螺紋（法蘭）、固定孔（支架）。 </p> <p> ● 探頭可加長：適應寒冷地區(qū)室外密閉容器安裝，防止結霜。 </p> <p> ● 配有高低位雙繼電器：四線制提供此功能。 </p> <p> ● 交流和直流供電形式可選：四線制和分體機主機提供此功能。甘肅水處理液位計用途液位計正確選型才能保證液位計更好的使用。</p><div

1、精密功能檢查 </p> <p> 精度等級和功能根據(jù)測量要求和使用場合選擇儀表精度等級，做到經(jīng)濟合算。比如用于貿易結算、產(chǎn)品交接和能源計量的場合，應該選擇精度等級高些，如1.0級、0.5級，或者更高等級; 用于過程控制的場合，根據(jù)控制要求選擇不同精度等級;有些**是檢測一下過程流量，無需做精確控制和計量的場合，可以選擇精度等級稍低的，如1.5級、2.5級，甚至 4.0級，這時可以選用價格低廉的插入式液位計。 </p> <p> 2、可測量的介質 </p> <p> 測量介質流速、儀表量程與口徑測量一般的介質時，液位計的滿度流量可以在測量介質流速0.5-12m/s范圍內選用，范圍比較寬。選擇儀表規(guī)格(口徑)不一定與工藝管道相同，應視測量流量范圍是否在流速范圍內確定，即當管道流速偏低，不能滿足流量儀表要求時或者在此流速下測量準確度不能保證時，需要縮小儀表口徑，從而提高管內流速，得到滿意測量結果。 </p><p> 靜壓式液位計適用于石油化工、冶金、電力、制藥、供排水、環(huán)保等系統(tǒng)和行業(yè)的各種介質的液位測量。 </p> <p> 性能優(yōu)點：其機械結構對過載及腐蝕性介質具有高抵抗性；高精度、長期穩(wěn)定的陶瓷電容和進口擴散硅測量單元；密封的電子模塊及雙濾波壓力補償系統(tǒng)可抵抗氣候現(xiàn)場變化的影響；電子模塊可輸出4...20mA信號并同時帶有過壓保護的模塊；選擇集成的溫度傳感器Pt100可同時進行物位及溫度的測量；相應的附件可提供完整的測量方案。 </p> <p> 浮球液位變送器廣使用于煉油、化工、造紙、食品、及污水處理等行業(yè)。能對開口、密閉容器或地下池槽里的介質液位在儀表控制室內進行顯示、報警和控制。被檢測的介質可為水、油、酸、堿、工業(yè)污水等導電及非導電液體，并能克服液體的泡沫所造成的假液位的影響。雷達液位計的測量不受介質變化、溫度變化、惰性氣體及蒸汽、粉塵、泡沫等的影響。</p><div

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。在超聲波檢測技術中，不管那種超聲波儀器，都必須把電能轉換超聲波發(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，在遇到水面時被反射回來，又被換能器所接收并轉換為電信號，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。由超聲波在介質中傳播原理可知，若介質壓力、溫度、密度、濕度等條件一定，則超聲波在該介質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。投入式液位計采用帶不銹鋼隔離膜的擴散硅壓阻式壓力傳感器作為信號測量元件。甘肅水處理液位計用途</p><p style="text-indent:25px">導波雷達液位計應用于水液儲罐、酸堿儲罐、漿料儲罐、固體顆粒、小型儲油罐。寧夏汽油液位計</p><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力波脈沖，脈沖速度已知，計算脈沖傳播時間即對應液位**變化。 </p> <p> 精度較高。適用于油類液體。 </p> <p> 安裝維護復雜，市場普及率低。（注：脈沖原理，疑也有雷達液位計的缺點）寧夏汽油液位計</p><p
