style="text-indent:25px">孔板流量計的取壓方式孔板流量計的取壓方式有以下幾種：1、角接取壓包括鉆孔取壓和環(huán)室取壓，有利于縮短直管段，精度較高。其中鉆孔取壓適合管徑為DN400-DN3000，環(huán)室取壓適合DN50-DN400。2、法蘭取壓具有加工簡單、易安裝易清理等特點，但精度低于角接取壓，適合管徑為DN50-DN1000。3、徑距取壓點固定，適合雷諾數(shù)大的場合，適合管徑為DN50-DN1000。環(huán)室取壓就屬于角接取壓，用上環(huán)室進行均壓效果更好一些，但是DN600的孔板用環(huán)室成本就提高不少，若只用法蘭式角接取壓安裝時要注意到位也行，準(zhǔn)確度會有所降低；法蘭取壓較簡單，容易裝配，但準(zhǔn)確度較角接取壓低一些；此外還有徑距取壓，但其壓差較小不易測量，因此很少采用，但徑距取壓適用于大管道的過熱蒸汽測量；根據(jù)你這種情況采用環(huán)室角接取壓效果，準(zhǔn)確度和靈敏度都高，但是成本稍高一些。</p><p> 變送器零點漂移：如果使用時間較長，變送器的零點可能會發(fā)生漂移，如果是負漂移，顯示壓差將會減小，顯示的流量也會減小。解決辦法：對變送器的零點進行校正。上下游直管段長度不夠，上下游直管段如果不夠長，氣體將得不到充分發(fā)展，會使計量結(jié)果造成較大誤差，如果上游在規(guī)定直管段內(nèi)存在多個彎頭，將使計量結(jié)果偏低。解決辦法：改造蒸汽管道，是上下游直管段長度達到規(guī)定要求。在節(jié)流裝置前加整流器。、差壓變送器的三閥組漏氣，如果三閥組中的高壓閥貨平衡閥漏氣，將會導(dǎo)致測量差壓值減小，測量結(jié)果就會偏低。解決辦法：如果三閥組中的高壓閥門漏氣，將該閥門進行緊固，必要時進行更換，如果三閥組中的平衡閥內(nèi)漏，將該閥門進行緊固，必要時進行更換。 </p> <p> <br /> </p> <p> <br /> 便攜式超聲波流量計具有很大的機動性，首要用于對不一樣管道的流體流量作臨時性丈量。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川液體渦輪流量計源頭直供廠家,流量計"

流體流經(jīng)管道內(nèi)的節(jié)流裝置，在節(jié)流件附近造成局部收縮，流速增加，在其上、下游兩側(cè)產(chǎn)生靜壓力差。在已知有關(guān)參數(shù)的條件下，根據(jù)流動連續(xù)性原理和伯努利方程可以推導(dǎo)出差壓與流量之間的關(guān)系而求得流量。孔板流量計的節(jié)流裝置結(jié)構(gòu)簡單，且牢固、性能穩(wěn)定可靠，使用期限長，價格較低，是工業(yè)中常用到的流量測量儀表，整個加工過程采用國際標(biāo)準(zhǔn)，并經(jīng)過嚴(yán)格的校驗檢測，用戶在購買后可放心使用。該流量計應(yīng)用領(lǐng)域比較，所有的單相流速都可以測量，一部分混相流也可以使用該產(chǎn)品孔板流量計可測量管道中各種流體的流量，可測量的介質(zhì)有液體、氣體、蒸汽，被應(yīng)用于石油、化工、冶金、輕工、煤礦等工業(yè)部門。測量原理：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，流束將在節(jié)流裝置的節(jié)流件處形成局部收縮孔板流量計前后產(chǎn)生一個靜壓力差,該壓力差與流量存在著一定的函數(shù)關(guān)系,流量越大,壓力差就越大.差壓信號傳送給差壓變送器。流量計有堰槽式流量計，它是通過測量液位來反映流量。四川液體渦輪流量計源頭直供廠家</p><p
