浮球液位計(jì)結(jié)構(gòu)主要是基于浮力和靜磁場原理設(shè)計(jì)生產(chǎn)的。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(dǎo)致磁性浮子位置的變化。浮球中的磁體和傳感器（磁簧開關(guān)）作用，使串連入電路的元件（如定值電阻）的數(shù)量發(fā)生變化，進(jìn)而使儀表電路系統(tǒng)的電學(xué)量發(fā)生改變。也就是使磁性浮子位置的變化引起電學(xué)量的變化。通過測量電學(xué)量的變化來反映容器內(nèi)液位的情況。 </p> <p> 2、特點(diǎn)及適用場合 </p> <p> 2.1結(jié)構(gòu)簡單、使用方便 </p> <p> 2.2性能穩(wěn)定、使用壽命長、便于安裝維護(hù) 幾乎可以適用于各種工業(yè)自動化過程控制中的液位測量和控制，可以運(yùn)用于石油加工、食品加工、化工、水處理、制藥、電力、造紙、冶金、船舶和鍋爐等領(lǐng)域中的液位測量、控制與檢測。 </p><p> 浮筒液位（界面）計(jì) </p> <p> 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)而成的液位測量儀表，儀表可用來測量液位、界位和密度，負(fù)責(zé)上下限報(bào)警信號輸出。**于測量壓力容器內(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：±0.5%FS </p> <p> 優(yōu)點(diǎn)：測量精度高； </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。電磁超聲波液位計(jì)是根據(jù)法拉弟電磁感應(yīng)定律制成的一種測量導(dǎo)電性液體的儀表。</p><div style="width:100%;text-align:

</p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 缺點(diǎn)：音叉開關(guān)不適合用于非常粘的介質(zhì)。導(dǎo)致叉子被連接在一起的叉間物料堆積，將干擾物位檢測。 </p> <p> <br />

電容式液位開關(guān)的測量原理是：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> 外測液位開關(guān) </p> <p> 外測液位開關(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。其測量探頭安裝在容器外壁上，屬于一種從罐外檢測液位的完全非接觸檢測儀表。儀表測量探頭發(fā)射超聲波，并檢測其在容器壁中的余振信號，當(dāng)液體漫過探頭時(shí)，此余振信號的幅值會變小，這個(gè)改變被儀表檢測到后輸出一個(gè)開關(guān)信號，達(dá)到液位報(bào)警的目的。
