<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(mào)易結(jié)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(zhì) </p> <p> 測量介質(zhì)流速，加油站液位計價格、儀表量程與口徑測量一般的介質(zhì)時，液位計的滿度流量可以在測量介質(zhì)流速0.5-12m/s范圍內(nèi) 選用，范圍比較寬，加油站液位計價格。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(nèi)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(nèi)流速，得到滿意測量結(jié)果。磁浮子液位計和頂裝浮球液位計，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。加油站液位計價格</p><div

雷達液位計具有故障報警及自診斷功能。根據(jù)操作顯示模塊提示的錯誤代碼分析故障，及時確定故障予以排除，使維護校正更加方便、準確，保障儀表的正常運行。 </p> <p> 適用范圍廣，幾乎可以測量所有介質(zhì); </p> <p> 從槽罐體的形狀來說，雷達液位計可以對球罐、臥罐、柱形罐、圓柱椎體罐等的液位進行測量;從罐體功能來說，可以對儲罐、緩沖罐、微波管、旁通管中的液位進行測量;從被測介質(zhì)來說，可以對液體、顆粒、料漿等進行測量。加油站液位計價格液位計常規(guī)檢查及故障解決方法,適用于磁翻板液位計，雙色石英管液位計，玻璃管液位計等。</p><div style="width:100%;text-align:

帶有磁體的浮球在被測介質(zhì)中的位置受浮力作用影響：液位的變化導致磁性浮子位置的變化。 </p> <p> 浮球中的磁體和傳感器作用，使串連入電路的元件的數(shù)量發(fā)生變化，進而使儀表電路系統(tǒng)的電學量發(fā)生改變。通過檢測電學量的變化來反映容器內(nèi)液位的情況。 </p> <p> 應用場合及特點: </p> <p> 應用場合：浮球液位計可適用于高溫、高壓、粘稠、臟污介質(zhì)、瀝青、含臘等油品以及易燃、易爆、腐蝕性等介質(zhì)的液位(界位)的連續(xù)測量。 </p> <p> 特點：浮球液位計結(jié)構(gòu)簡單，調(diào)試方便，可靠性好，精度高等。 </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。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

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）導波雷達物位計對蒸汽和泡沫有很強的阻止能力，測量不受影響。加油站液位計價格</p><p style="text-indent:25px">浮子式液位計和被測容器形成連通器，保證被測量容器與測量管體間的液位相等。加油站液位計價格</p><p> 帶有液位變送器的磁翻板液位計，應使用備用工具磁鋼吸引浮子室內(nèi)磁浮子運動，模擬液位變化，來檢測液位變送器工作是否正常。對于防爆型儀表不*要檢測變送器的工作狀態(tài)參數(shù)，還要檢測器防爆性能。另外： </p> <p> a.液位計變送器和關聯(lián)設備之間的連接電纜為二芯屏蔽電纜，電纜芯線截面應不小于0.5mm。電纜的屏蔽層應在安全場所接地。 </p> <p> b.有防爆要求的儀表安裝時，維修必須在安全場所進行。在安裝和維修時必須切斷電源。在確認電源斷開后，再打開儀表接線盒。儀表的接線盒上的接地端子必須接有可靠的地線。在調(diào)整和使用的過程中，應注意保護儀表接線盒上的防爆螺紋接合面，不得有劃痕、碰撞等損傷。 </p> <p> c.儀表現(xiàn)場顯示部分投入運行后，接好電遠傳后，蓋上儀表接線盒，確認密封后通電。觀察數(shù)字顯示儀的液位值，如果電遠傳的液位值與現(xiàn)場顯示的液位值不一致時，可以松開喉箍，適當調(diào)整變送器的上下位置，直到達到一致。然后緊固喉箍。 </p> <p> d.帶有報警開關的液位計其報警開關為無源干接點開關。開關大體上可以分為常開、常閉、自保持等幾種，也可以根據(jù)用戶的需要，制作單刀雙擲開關。本液位計配套的液位計控制器主要用于控制小功率負載。不能用于直接控制大功率負載. 加油站液位計價格</p></p><br /><p>文章來源地址:
