孔板流量計(jì)安裝對(duì)管道的要求： </p> <p> 1．孔板流量計(jì)安裝時(shí)應(yīng)配有一段測(cè)量管,至少保持**DN、后5DN的等徑直管段，以提高測(cè)量精度。 </p> <p> 2．在孔板流量計(jì)前后若需安裝閥門，比較好選閘閥且在運(yùn)行中全開(kāi)；調(diào)節(jié)閥則應(yīng)在下游5DN之后的管路中。 </p> <p> 3．引壓管路的內(nèi)徑與管路長(zhǎng)度和介質(zhì)臟污程度有關(guān)，通常在45米以內(nèi)用內(nèi)徑為8-12mm的管子，四川氣體渦輪流量計(jì)源頭直供廠家。 </p> <p> 4．測(cè)量液體流量時(shí)引壓管水平段應(yīng)在同一水平面內(nèi)。若是在垂直管道上安裝節(jié)流件，引壓短管之間相距一定的距離（垂線方向），這對(duì)差壓變送器的零點(diǎn)有影響，應(yīng)通過(guò)“零點(diǎn)遷移”來(lái)校正。 </p> <p> 5．引壓管路應(yīng)有牢固的支架托承，兩根取壓管路應(yīng)盡可能互相靠近并遠(yuǎn)離熱源或震動(dòng)源，測(cè)量水蒸汽流量時(shí)，應(yīng)用保溫材料一同包扎，必須時(shí)（如氣溫0℃以下）加伴熱管防止結(jié)冰。在測(cè)量臟污流量時(shí)，四川氣體渦輪流量計(jì)源頭直供廠家，應(yīng)附設(shè)隔離器或沉降器。 </p> <p> 6．引壓管路內(nèi)必須始終保持單相流體狀態(tài)。被測(cè)流體是氣體時(shí)，引壓管路（包括差壓計(jì)的壓力腔）內(nèi)全部是氣相；被測(cè)流體是液體時(shí)，引壓管路內(nèi)全部是液相，四川氣體渦輪流量計(jì)源頭直供廠家，不能有氣泡。為此應(yīng)在引壓管路的比較低點(diǎn)裝排水閥或在比較高點(diǎn)裝排氣閥，在新裝或檢修差壓變送器時(shí)時(shí)應(yīng)特別注意。質(zhì)量流量計(jì)的測(cè)量管無(wú)論是向上還是向下安裝，都要盡量使測(cè)量管與地平面保持垂直或水平。四川氣體渦輪流量計(jì)源頭直供廠家</p><div

孔板流量計(jì)使流速增加，靜壓力低，于是在節(jié)流件前后便產(chǎn)生了壓力降，即壓差，介質(zhì)流動(dòng)的流量越大，在節(jié)流件前后產(chǎn)生的壓差就越大，所以孔板流量計(jì)可以通過(guò)測(cè)量壓差來(lái)衡量流體流量的大小。這種測(cè)量方法是以能量守衡定律和流動(dòng)連續(xù)性定律為基準(zhǔn)的。<span style="font-size:12px;">孔板流量計(jì)可測(cè)量管道中各種流體的流量，可測(cè)量的介質(zhì)有液體、氣體、蒸汽，被廣泛應(yīng)用于石油、化工、冶金、輕工、煤礦等工業(yè)部門。測(cè)量原理：充滿管道的流體，當(dāng)它們流經(jīng)管道內(nèi)的節(jié)流裝置時(shí)，流束將在節(jié)流裝置的節(jié)流件處形成局部收縮.</span>

style="text-indent:25px">智能電磁流量計(jì)傳感器接地很重要，尤其在管道存在雜散電流干擾時(shí)，只有良好的接地保護(hù)，才能使智能電磁流量計(jì)準(zhǔn)確地測(cè)量。也許在沒(méi)有這種干擾的環(huán)境里，不接地并不影響流量計(jì)準(zhǔn)確測(cè)量，但是一旦環(huán)境改變，即造成流量計(jì)不能準(zhǔn)確穩(wěn)定地工作，所以我們?cè)诎惭b時(shí)比較好做好傳感器接地保護(hù)，給智能電磁流量計(jì)創(chuàng)造一個(gè)良好的工作環(huán)境。接地環(huán)分為普通型和保護(hù)型，一般是使用普通型，若被測(cè)介質(zhì)是磨損性的，宜使用帶頸的保護(hù)接地環(huán)。以保護(hù)進(jìn)口端的襯里，延長(zhǎng)使用壽命。若口徑在200mm以下的智能電磁流量計(jì)，選用聚四氟乙烯襯里時(shí)，應(yīng)選用接地環(huán)，以保證在管道連接安裝時(shí)保護(hù)襯里不受損壞，接地環(huán)通常是不銹鋼或Hc合金的。</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(shuō)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。孔板流量計(jì)孔板計(jì)算采用國(guó)際標(biāo)準(zhǔn)與加工；四川氣體渦輪流量計(jì)源頭直供廠家</p><p
