zui低料位也就是使超聲波能到達(dá)的距離傳感器的zui遠(yuǎn)距離，并且使反射回波能被傳感器接收。由于超聲波在傳播過程中的衰減以及物料表面對聲波的吸收，這一傳播距離對物料性質(zhì)依賴性很強(qiáng)，對于DU33來說，西安桿式導(dǎo)波雷達(dá)物位計(jì)，可測液體范圍為25m，固體范圍為15m。 </p> <p> 總之，只要儀表選型、安裝適當(dāng)，超聲波物位計(jì)的應(yīng)用效果還是比較滿意的，西安桿式導(dǎo)波雷達(dá)物位計(jì)。 </p> <p> 超聲波類儀表(超聲波流量計(jì))是現(xiàn)代科學(xué)技術(shù)在工業(yè)測量中的具體運(yùn)用，是高新電子技術(shù)和聲學(xué)原理相結(jié)合的產(chǎn)物。比起常規(guī)儀表，西安桿式導(dǎo)波雷達(dá)物位計(jì)，它們的智能化更高，應(yīng)用的技術(shù)更先進(jìn)，也給用戶帶來更大方便。雷達(dá)物位計(jì)在使用上具有的優(yōu)勢：由于雷達(dá)物位計(jì)不與被測介質(zhì)接觸，且受溫度、壓力、氣體等影響非常小。西安桿式導(dǎo)波雷達(dá)物位計(jì)</p><div

超聲波液位計(jì)用途：液位和料位測量是工業(yè)上經(jīng)常遇到的一個問題，超聲測位技術(shù)有很多優(yōu)點(diǎn)，它不僅能定點(diǎn)和連續(xù)測位，而且能方便的提供遙測或遙控所需的信號。與放射性測位技術(shù)相比，超聲技術(shù)不需要防護(hù)，與激光測距技術(shù)相比，它又有簡單和經(jīng)濟(jì)的優(yōu)點(diǎn)，同時超聲技術(shù)一般不需要運(yùn)動部件，所以在安裝和維護(hù)上又相應(yīng)比較方便。超聲波物位計(jì)可廣泛應(yīng)用于石油、礦業(yè)、發(fā)電廠、化工廠、水處理廠、污水處理站、農(nóng)業(yè)用水、環(huán)保監(jiān)測、食品（釀酒業(yè)，飲料業(yè)、添加劑、食用油、奶制品）、抗洪防汛、水文監(jiān)測、明渠、空間定位等許多行業(yè)。超聲波物位計(jì)原理：物位測量過程中，超聲波信號由超聲波探頭發(fā)出，經(jīng)液體或固體物料表面反射后折回，由同一個探頭接收，測量超聲波的整個運(yùn)行時間，從而實(shí)現(xiàn)物位的測量。聲波傳輸距離與聲速和聲傳輸時間的關(guān)系可用公式表示：超聲波物位計(jì)的算式L：超聲波探頭距所測料面距離。單位：m；v：經(jīng)溫度補(bǔ)償后的聲速值。單位：m/s；t：測量范圍內(nèi)聲波的運(yùn)行時間。甘肅導(dǎo)波雷達(dá)物位計(jì)特點(diǎn)超聲波物位計(jì)具有高精度，高穩(wěn)定性能，較強(qiáng)抗干擾能力，發(fā)射角小，發(fā)射頻率高，防過壓防雷擊等功能。</p><div

射頻電容物位計(jì)可以解決大多數(shù)高溫，高壓，腐蝕性液位的測量。它采用美國公司射頻電容技術(shù)和芯片及聚四氟乙烯做絕緣材料。與雙法蘭液位計(jì)，浮筒式液位計(jì)，同位素式液位計(jì)相比，它是一種簡單，耐用，方便的儀表。 </p> <p> 特點(diǎn):<span style="display:none;"></span>結(jié)構(gòu)簡單，安裝容易。耐腐蝕性強(qiáng)，用聚四氟乙烯做探桿。耐高溫，一般為200℃，特殊可達(dá)到1000℃。耐高壓，zui高壓為32MPa。 <p> 原理用途： </p> <p> 如果將探桿和容器壁視做兩塊相互平行的電極板，被測液體視做它們之間的介質(zhì)，那么一個簡單的電容形成了。當(dāng)液位上升時，電容量就會增加，射頻電路將這一變化轉(zhuǎn)換為模擬信號輸出。酸類，堿類，氯化物，有機(jī)溶劑，液態(tài)CO2，氨水，PVC粉料，灰料，油水界面，中藥等液**測量。 </p> 射頻導(dǎo)納物位計(jì)通用性強(qiáng),可抗粘附,探頭可拆,耐高低溫,并且具有智能診斷等。甘肅導(dǎo)波雷達(dá)物位計(jì)特點(diǎn)</p><p style="text-indent:25px">雷達(dá)物位計(jì)已成為物位測量儀表市場上的主流產(chǎn)品，主要分為雷達(dá)物位計(jì)和導(dǎo)波雷達(dá)物位計(jì)。西安桿式導(dǎo)波雷達(dá)物位計(jì)</p><p> 液體、物位的測量：對于液面相對平穩(wěn)的罐體，且被測液體的介電常數(shù)較高，可以選擇普通雷達(dá)物位計(jì)。對于液面波動大、或帶有攪拌的罐體，或被測液體的介電常數(shù)較低，應(yīng)推薦導(dǎo)波雷達(dá)。因?yàn)閷?dǎo)波管對液面有整型作用，且導(dǎo)波雷達(dá)的微波反射不易受環(huán)境條件變化的影響。被測液體的介電常數(shù)和密度變化對測量結(jié)果沒有影響。對于被測液體的粘度≥500cst，且液體粘附性較強(qiáng)的情況，不能選擇導(dǎo)波管方式測量，因?yàn)檎掣胶徒Y(jié)晶會堵死導(dǎo)波管。從而形成虛假物位。可以選擇導(dǎo)波桿方式來測量。當(dāng)介質(zhì)在探頭上的涂污對測量物位的影響可分為兩種：膜狀涂污和橋接。膜狀涂污是在物位降低時，高粘液體或輕油漿在探頭上形成的一種覆蓋層。由于這種涂污在探頭上涂層均勻，因此對測量基本無影響；但橋接性涂污的形成卻能導(dǎo)致明顯的測量誤差，當(dāng)塊狀或條狀介質(zhì)污垢粘結(jié)于波導(dǎo)體上或橋接于兩個波導(dǎo)體之間時，就會在該點(diǎn)測得虛假物位。西安桿式導(dǎo)波雷達(dá)物位計(jì)</p></p><br
