優(yōu)點(diǎn)：測量光束發(fā)散角小，方向性好；量程大，測距遠(yuǎn)、盲點(diǎn)小；不受介質(zhì)溫度影響；非插入式測量，非接觸測量；測量速度快，適合變化快的液位及料位測量；操作簡單，可編程測量；測量精確、高精度適合高要求項目；分辨率高出一般表十倍；波束角小，適合長距離定位，避免障礙物。 </p> <p> 缺點(diǎn)：易受測試波段光源干擾、深色被測物吸收；價位高。雷達(dá)液位計采用非接觸式測量，不受槽內(nèi)液體的密度、濃度等物理特性的影響。天津80HZ調(diào)頻雷達(dá)料位計生產(chǎn)廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

液位開關(guān)，顧名思義，就是用來控制液位的開關(guān)。從形式上主要分為接觸式和非接觸式。非接觸式的如電容式液位開關(guān),接觸式的例如:浮球式液位開關(guān)、電極式液位開關(guān)、電子式液位開關(guān)。電容式液位開關(guān)也可以采用接觸式方法實現(xiàn)。 </p> <p> 液位開關(guān)種類及原理 </p> <p> 浮球液位開關(guān) </p> <p> 浮球液位開關(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，產(chǎn)生開關(guān)信號。 </p> <p> 音叉液位開關(guān) </p> <p> 音叉液位開關(guān)的工作原理是通過安裝在基座上的一對壓電晶體使音叉在一定共振頻率下振動。當(dāng)音叉液位開關(guān)的音叉與被測介質(zhì)相接觸時，音叉的頻率和振幅將改變，音叉液位開關(guān)的這些變化由智能電路來進(jìn)行檢測，處理并將之轉(zhuǎn)換為一個開關(guān)信號，達(dá)到液位報警或控制的目的。為了讓音叉伸到罐內(nèi)，通常使用法蘭或者帶螺紋的工藝接頭將音叉開關(guān)安裝到罐體的側(cè)面或者頂部。 </p><p> 導(dǎo)波雷達(dá)液位計與普通雷達(dá)液位計的比較 </p> <p> 普通雷達(dá)為非接觸式測量，導(dǎo)波雷達(dá)為接觸式測量，這樣就意味導(dǎo)波雷達(dá)更需考慮介質(zhì)的腐蝕性和粘附性，而且過長的導(dǎo)波雷達(dá)安裝和維護(hù)更加困難。普通雷達(dá)可以互換使用，而導(dǎo)波雷達(dá)由于導(dǎo)波桿（纜）長度根據(jù)原工況固定，一般不能互換使用，受此影響導(dǎo)波雷達(dá)的選型要比普通雷達(dá)麻煩。 </p> <p> 測量固體物料時，導(dǎo)波雷達(dá)還要考慮導(dǎo)波桿（纜）的受力情況，也是由于受力的原因一般用導(dǎo)波雷達(dá)的測量距離不會很長，而普通雷達(dá)在30、40m的罐體上應(yīng)用比較常見，甚至可測到60m。另外一般的導(dǎo)波雷達(dá)還有底部探測功能，可以根據(jù)底部回波信號能測量值加以修正，使信號更為穩(wěn)定準(zhǔn)確。渦輪超聲波液位計它采用多葉片的轉(zhuǎn)子（渦輪）感受流體平均流速,從而且推導(dǎo)出流量或總量的儀表。</p><div
