差壓式超聲波液位計(jì)工作原理：差壓式超聲波液位計(jì)是根據(jù)安裝于管道中流量檢測(cè)件產(chǎn)生的差壓,已知的流體條件和檢測(cè)件與管道的幾何尺寸來(lái)計(jì)算流量的儀表。差壓式超聲波液位計(jì)由一次裝置（檢測(cè)件）和二次裝置（差壓轉(zhuǎn)換和流量顯示儀表）組成。通常以檢測(cè)件形式對(duì)差壓式超聲波液位計(jì)分類(lèi),如孔板超聲波液位計(jì)、文丘里超聲波液位計(jì)、均速管超聲波液位計(jì)等。二次裝置為各種機(jī)械、電子、機(jī)電一體式差壓計(jì),差壓變送器及流量顯示儀表。它已發(fā)展為三化（系列化、通用化及標(biāo)準(zhǔn)化）程度很高的、種類(lèi)規(guī)格龐雜的一大類(lèi)儀表,它既可測(cè)量流量參數(shù),也可測(cè)量其它參數(shù)（如壓力、物位、密度等）。差壓式超聲波液位計(jì)的檢測(cè)件按其作用原理可分為:節(jié)流裝置、水力阻力式、離心式、動(dòng)壓頭式、動(dòng)壓頭增益式及射流式幾大類(lèi)。檢測(cè)件又可按其標(biāo)準(zhǔn)化程度分為二大類(lèi):標(biāo)準(zhǔn)的和非標(biāo)準(zhǔn)的。所謂標(biāo)準(zhǔn)檢測(cè)件是只要按照標(biāo)準(zhǔn)文件設(shè)計(jì)、制造、安裝和使用,無(wú)須經(jīng)實(shí)流標(biāo)定即可確定其流量值和估算測(cè)量誤差。非標(biāo)準(zhǔn)檢測(cè)件是成熟程度較差的,尚未列入國(guó)際標(biāo)準(zhǔn)中的檢測(cè)件。差壓式超聲波液位計(jì)是一類(lèi)應(yīng)用的超聲波液位計(jì),在各類(lèi)流量?jī)x表中其使用量占居**。近年來(lái),由于各種新型超聲波液位計(jì)的問(wèn)世,它的使用量百分?jǐn)?shù)逐漸下降。 </p><p> 頂裝磁翻板液位計(jì)是安裝在容器頂部的一種安裝方式，非常適合一些地下儲(chǔ)罐，或側(cè)面不方便開(kāi)孔的容器，或所測(cè)液體介質(zhì)粘度較大不易采用側(cè)裝的液位計(jì)等等。頂裝磁翻板液位計(jì)一般分為上下兩部分結(jié)構(gòu)。上部分為液位計(jì)的主測(cè)量管，在管外捆綁有帶磁性翻片的顯示面板，用于指示液體的液位，這部分被安裝在容器的頂部，通過(guò)法蘭與容器的法蘭連接，一般選配DN80或DN100法蘭即可，法蘭規(guī)格不宜小于DN80；下部分為導(dǎo)筒部分，為浮子的通道，導(dǎo)筒內(nèi)浮子通過(guò)連桿與上部測(cè)量管內(nèi)的磁性浮球連成一體，當(dāng)液位出現(xiàn)上下變化時(shí)，浮子帶動(dòng)磁鋼在導(dǎo)筒內(nèi)上下移動(dòng)，利用上浮子的磁耦合的作用驅(qū)動(dòng)顯示面板內(nèi)的翻片翻轉(zhuǎn)指示出液位。在浮筒外還可捆綁干簧管液位變送器以實(shí)現(xiàn)信號(hào)遠(yuǎn)距離傳送和自動(dòng)控制。1、磁翻板液位計(jì)在安裝時(shí)護(hù)導(dǎo)管和主體測(cè)量管必須要保持垂直，上下浮球連桿不能彎曲，必須挺直插入；2、磁翻板液位計(jì)安裝位置應(yīng)避開(kāi)加液口，防止液位計(jì)護(hù)導(dǎo)管或浮球受到?jīng)_擊；3、安裝連接法蘭不宜選得太小，否則容易造成盲區(qū)過(guò)大，且因護(hù)筒小浮子運(yùn)行阻力也較大，浮子運(yùn)行容易卡住，一般安裝連接法蘭不小于DN80為宜；4、在安裝防腐型液位計(jì)時(shí)，注意不要破壞防腐層，以使防腐層失效。界面：兩種互不相溶的物質(zhì)的界面位置。</p><div
