1.恒浮力式液位計原理：在整個測量過程中其浮力維持不變，·在工作時浮標(biāo)隨液位面高、低而變化，如浮標(biāo)式、浮球式液位計、浮子鋼帶液位計等;其中浮球式液位計特別適用高溫、高粘度、小測暈范圍的液位測量。浮子鋼帶液位計則是用于大的球罐和柱罐的液位測量。 2.變浮力式液位計原理:它根據(jù)浮簡在液體內(nèi)浸沒的深度不同而所受浮力不同來測量液位，如浮筒式液位計，可用來測高溫、高壓介質(zhì)的液位。</p><p style="text-indent:25px">靜壓式液位計（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(zhì)的液位測量。精巧的結(jié)構(gòu)，簡單的調(diào)校和靈活的安裝方式為用戶輕松地使用提供了方便。4～20mA、 0～5v、 0～10mA等標(biāo)準(zhǔn)信號輸出方式由用戶根據(jù)需要任選。功能特點： 1、穩(wěn)定性好，滿度、零位長期穩(wěn)定性可達(dá) 0.１%FS/ 年。在補償溫度 0 ～ 70 ℃范圍內(nèi)，溫度飄移低于 0.１%FS ，在整個允許工作溫度范圍內(nèi)低于 0.３%FS 。 2、具有反向保護、限流保護電路，在安裝時正負(fù)極接反不會損壞變送器，異常時送器會自動限流在 35MA 以內(nèi)。 3、固態(tài)結(jié)構(gòu)，無可動部件，高可靠性，使用壽命長。 4、安裝方便、結(jié)構(gòu)簡單、經(jīng)濟耐用。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">磁浮球液位計（液位開關(guān)）結(jié)構(gòu)主要基于浮力和靜磁場原理設(shè)計生產(chǎn)的。帶有磁體的浮球（簡稱浮球）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，使串聯(lián)入電路的元件（如定值電阻）的數(shù)量發(fā)生變化，進而使儀表電路系統(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。通過檢測電學(xué)量的變化來反映容器內(nèi)液位的情況。該液位計可以直接輸出電阻值信號，也可以配合使用變送模塊，輸出電流值（4～20mA）信號；同時配合其他轉(zhuǎn)換器，輸出電壓信號或者開關(guān)信號（也可以按照客戶需求轉(zhuǎn)換器由公司配送）。從而實現(xiàn)電學(xué)信號的遠(yuǎn)程傳輸、分析與控制。攀枝花液位儀表供應(yīng)</p><p

style="text-indent:25px">很多現(xiàn)場在出現(xiàn)液位異常波動的問題經(jīng)過判斷查找，并不是儀表本體的問題，經(jīng)常是由于液位控制系統(tǒng)的調(diào)節(jié)性能造成的。這時要和工藝人員結(jié)合檢查進料、出料情況，確定工藝狀況正常后，可通過調(diào)整液位控制回路的PID參數(shù)來穩(wěn)定液位數(shù)值。具體方法是：調(diào)節(jié)閥投手動狀態(tài)，先調(diào)整設(shè)定值與測量值一致，使液位波動平穩(wěn)下來，再慢慢調(diào)整調(diào)節(jié)閥開度，使液位緩慢上升或下降，達(dá)到工藝要求，再調(diào)整設(shè)定值與測量值一致，待參數(shù)穩(wěn)定后調(diào)節(jié)閥投自動?？傊?，一旦發(fā)現(xiàn)儀表參數(shù)有些異常，首先與工藝人員結(jié)合，從工藝操作系統(tǒng)和現(xiàn)場儀表系統(tǒng)兩方面入手，綜合考慮，認(rèn)真分析，特別要考慮被測參數(shù)和控制閥之間的關(guān)聯(lián)，將故障分步分段判定，也就很容易找出問題所在，對癥下藥解決問題。攀枝花液位儀表供應(yīng)</p><p
