<p> 1、工作原理浮筒液位計(jì)由四個(gè)基本部分組成：浮筒、彈簧、磁鋼室和指示器。浸在液體中的浮筒受到向下的重力，向上的浮力和彈簧彈力的復(fù)合作用。當(dāng)這三個(gè)力達(dá)到平衡時(shí)，浮筒就靜止在某一位置。當(dāng)液位發(fā)生變化時(shí)，浮筒所受浮力相應(yīng)改變，平衡狀態(tài)被打破，從而引起彈力變化即彈簧的伸縮，以達(dá)到新的平衡。彈簧的伸縮使其與剛性連接的磁鋼產(chǎn)生位移。這樣，通過指示器內(nèi)磁感應(yīng)元件和傳動(dòng)裝置使其指示出液位。 </p> <p> 2、特點(diǎn)及適用場(chǎng)合 </p> <p> 2.1現(xiàn)場(chǎng)指示，江西雷達(dá)液位計(jì)哪家比較好、遠(yuǎn)傳兼容； </p> <p> 2.2測(cè)量范圍大，比較大可達(dá)3000mm； </p> <p> 2.3工作可靠，良好的精度和靈敏度； </p> <p> 2.4耐高溫、高壓，耐腐蝕性能強(qiáng)； </p> <p> 2.5現(xiàn)場(chǎng)調(diào)試方便，易于檢查和維護(hù)，江西雷達(dá)液位計(jì)哪家比較好。由于它直觀、穩(wěn)定、可靠性高、因而對(duì)連續(xù)生產(chǎn)的煉油、化工中的重要容器、設(shè)備，如塔類、貯罐中間容器等的液位測(cè)量都非常適用，但不適合高粘度介質(zhì)液位的測(cè)量，江西雷達(dá)液位計(jì)哪家比較好。液位開關(guān)是一種結(jié)構(gòu)簡(jiǎn)單、使用方便、安全可靠的液位控制器。江西雷達(dá)液位計(jì)哪家比較好</p><div

電容式液位開關(guān)的測(cè)量原理是：固體物料的物位高低變化導(dǎo)致探頭被覆蓋區(qū)域大小發(fā)生變化，從而導(dǎo)致電容值發(fā)生變化。探頭與罐壁（導(dǎo)電材料制成）構(gòu)成一個(gè)電容。探頭處于空氣中時(shí)，測(cè)量到的是一個(gè)小數(shù)值的初始電容值。當(dāng)罐體中有物料注入時(shí)，電容值將隨探頭被物料所覆蓋區(qū)域面積的增加而相應(yīng)地加大，開關(guān)狀態(tài)發(fā)生變化。 </p> <p> 外測(cè)液位開關(guān) </p> <p> 外測(cè)液位開關(guān)是一種利用“變頻超聲波技術(shù)”實(shí)現(xiàn)的非接觸式液位開關(guān)，使用于各種液體的液體檢測(cè)。其測(cè)量探頭安裝在容器外壁上，屬于一種從罐外檢測(cè)液位的完全非接觸檢測(cè)儀表。儀表測(cè)量探頭發(fā)射超聲波，并檢測(cè)其在容器壁中的余振信號(hào)，當(dāng)液體漫過探頭時(shí)，此余振信號(hào)的幅值會(huì)變小，這個(gè)改變被儀表檢測(cè)到后輸出一個(gè)開關(guān)信號(hào)，達(dá)到液位報(bào)警的目的。

工作原理：浮筒液位計(jì)是根據(jù)阿基米德定律和磁耦合原理設(shè)計(jì)而成的液位測(cè)量?jī)x表，儀表可用來測(cè)量液位、界位和密度，負(fù)責(zé)上下限報(bào)警信號(hào)輸出。**于測(cè)量壓力容器內(nèi)液位，同四個(gè)基本部分組成：浮筒、彈簧、磁鋼室和指示器。 </p> <p> 應(yīng)用范圍：用于石油、化工、冶金、電力、醫(yī)藥、食品、造紙等行業(yè)液體的測(cè)量與過程控制。 </p> <p> 使用限制：一般的液態(tài)介質(zhì)都是可以測(cè)量的，但局限于小量程，大量程的浮筒液位計(jì)運(yùn)輸、安裝非常不方便，其他的費(fèi)用非常高，所以特別大量程的現(xiàn)場(chǎng)不建議使用浮筒液位計(jì)，超過5M基本上就沒有人做了 </p> <p> 精度等級(jí)：±0.5%FS </p> <p> 優(yōu)點(diǎn)：測(cè)量精度高； </p> <p> 智能化：利用HART通訊協(xié)議的該儀表使用戶容易存取過程操作的信息； </p> <p> 高靈敏：能反應(yīng)過程的小變化： </p> <p> 扭力管采用優(yōu)化的熱處理工藝，具有優(yōu)良的溫度和時(shí)間穩(wěn)定性； </p> <p> 結(jié)構(gòu)堅(jiān)固，耐腐蝕 </p> <p> 應(yīng)用面廣，適用性強(qiáng)。 </p> <p> 缺點(diǎn)：安裝，運(yùn)輸不方便，如果液罐過高則不適用。差壓式超聲波液位計(jì)應(yīng)用范圍特別大量,在封閉管道的流量測(cè)量中各種對(duì)象都有應(yīng)用；</p><div style="width:100%;text-align: center;"><img style="max-width:
