<p> 差壓式流量計(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。 </p> <p> <span style="font-size:12px;">差壓式流量計(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)差壓式流量計(jì)分類,如孔板流量計(jì)、文丘里流量計(jì)、均速管流量計(jì)等。</span> </p> <p> <span style="font-size:12px;">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、種類規(guī)格龐雜的一大類儀表,它既可測(cè)量流量參數(shù)，無(wú)錫電磁流量計(jì)多少錢,也可測(cè)量其它參數(shù)(如壓力、物位、密度等)。</span><span style="font-size:12px;">差壓式流量計(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，無(wú)錫電磁流量計(jì)多少錢、離心式，無(wú)錫電磁流量計(jì)多少錢、動(dòng)壓頭式、動(dòng)壓頭增益式及射流式幾大類。</span>

主要安裝要求是對(duì)于直管段的要求及管道振動(dòng)要求，渦街流量傳感器的上游側(cè)和下游側(cè)應(yīng)有較長(zhǎng)的直管段;管道不能有振動(dòng)，如有振動(dòng)，則需對(duì)流量計(jì)兩側(cè)加固定裝置。 </p> <p> 對(duì)于渦街流量計(jì)來(lái)說，測(cè)量氣體流量時(shí)，若被測(cè)氣體含有少量的液體，流量計(jì)應(yīng)安裝在管線的較高處。測(cè)量液體時(shí)，若被測(cè)液體中含有少量的氣體，流量計(jì)應(yīng)安裝在管線的較低處。測(cè)壓孔和測(cè)溫孔：需要測(cè)壓時(shí),須將測(cè)壓孔設(shè)置在流量計(jì)下游2~7D的地方。需要測(cè)溫時(shí),將溫度傳感器設(shè)置在離測(cè)壓點(diǎn)下游的1~2D之間處。 </p> <p> 管道支撐：盡量將流量計(jì)安裝在振動(dòng)加速度小于20m/s2的地方。當(dāng)管道振動(dòng)過強(qiáng)時(shí),應(yīng)對(duì)管道安裝加固支撐。封墊片：切不可將密封墊片突出到管道中,否則將導(dǎo)致無(wú)法接受的誤差。山東插入式巴類流量計(jì)銷售廠家孔板流量計(jì)又稱為差壓式流量計(jì),廣泛應(yīng)用于氣體、蒸汽和液體的流量測(cè)量。</p><div

src="https://tyunfile.71360.com/UploadFile/jszhck/637312837271718750/6710757.png"></div><p> 電磁流量計(jì)接地的原因： </p> <p> 電磁流量計(jì)內(nèi)的測(cè)量電極處于一個(gè)直流或交流電場(chǎng)內(nèi)，如果其環(huán)境不能有效地被屏蔽于一個(gè)無(wú)干擾的條件下，對(duì)測(cè)量有嚴(yán)重干擾。傳感器外殼接地與否，直接關(guān)系到測(cè)量的精度和穩(wěn)定性，接地導(dǎo)線必須不傳任何干擾電壓，因此電磁流量計(jì)要求有非?？煽康慕拥?，要做好接地屏蔽，否則就會(huì)產(chǎn)生干擾電流。<span style="font-size:12px;"> </span> </p> <p> 電磁流量計(jì)接地的好處： </p> <p> 若連接流量計(jì)的管道是(相對(duì)于被測(cè)介質(zhì))絕緣的則要用接地環(huán)，它的材質(zhì)應(yīng)根據(jù)被測(cè)介質(zhì)的腐蝕性選用。如果是聚四氟乙烯內(nèi)襯的測(cè)量傳感器，為了保測(cè)量傳感器能正常工作，要選用接地環(huán)。 </p> <p> 超聲波流量計(jì) </p><p> 電磁流量計(jì)的安裝與調(diào)試比其它流量計(jì)復(fù)雜，且要求更嚴(yán)格。變送器和轉(zhuǎn)換器必須配套使用，兩者之間不能用兩種不同型號(hào)的儀表配用。在安裝變送器時(shí)，從安裝地點(diǎn)的選擇到具體的安裝調(diào)試，必須嚴(yán)格按照產(chǎn)品說明書要求進(jìn)行。安裝地點(diǎn)不能有振動(dòng)，不能有強(qiáng)磁場(chǎng)。在安裝時(shí)必須使變送器和管道有良好的接觸及良好的接地。變送器的電位與被測(cè)流體等電位。在使用時(shí)，必須排盡測(cè)量管中存留的氣體，否則會(huì)造成較大的測(cè)量誤差。 </p> <p> 電磁流量計(jì)用來(lái)測(cè)量帶有污垢的粘性液體時(shí)，粘性物或沉淀物附著在測(cè)量管內(nèi)壁或電極上，使變送器輸出電勢(shì)變化，帶來(lái)測(cè)量誤差，電極上污垢物達(dá)到一定厚度，可能導(dǎo)致儀表無(wú)法測(cè)量。電磁流量計(jì)的常規(guī)直管段要求是**D后5D，在有彎管、閥門的情況分別有不同的要求。</p><div
