孔板流量計的節(jié)流裝置結構簡單，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準，并經(jīng)過嚴格的校驗檢測，用戶在購買后可放心使用。該流量計應用領域比較，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 </p> <p> 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 </p> <p> 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)關系,流量越大,壓力差就越大.差壓信號傳送給差壓變送器，鹽城液體渦輪流量計生產(chǎn)廠家,轉換成4-20ma，鹽城液體渦輪流量計生產(chǎn)廠家.DC模擬信號輸出,遠轉給流量積算儀,實現(xiàn)流體流量的計量，鹽城液體渦輪流量計生產(chǎn)廠家.質(zhì)量型流量計,利用智能型差壓變送器,對工況溫/壓進行自動補償后,實現(xiàn)對流體質(zhì)量流量的測量流量計是利用伯努利方程原理，通過測量流體差壓信號反映流量;鹽城液體渦輪流量計生產(chǎn)廠家</p><div

m;流動條件方面:亞音速、音速、脈動流等。它在各工業(yè)部門的用量約占流量計全部用量的 1/4~1/3。 </p> <p> 孔板以內(nèi)孔銳角線來保證精度，因此對腐蝕、磨損、結垢、臟污敏感，長期使用精度難以保證，需每年拆下強檢一次。采用法蘭連接，易產(chǎn)生跑、冒、滴、漏問題，增加了維護工作量。 </p> <p> 工業(yè)發(fā)達國家近年 PD流量計(不包括家用煤氣表和家用水表)的銷售金額占流量儀表的 13%~23%;我國約占 20%,1990 年產(chǎn)量(不包括家用煤氣表)估計為 34 萬臺,其中橢圓齒輪式和腰輪式分別約占 70%和 20%。鹽城液體渦輪流量計生產(chǎn)廠家電磁流量計的應用有一定局限性，它只能測量導電介質(zhì)的液體流量，不能測量非導電介質(zhì)的流量；</p><div

style="font-size:12px;">差壓式流量計由一次裝置(檢測件)和二次裝置(差壓轉換和流量顯示儀表)組成。通常以檢測件形式對差壓式流量計分類,如孔板流量計、文丘里流量計、均速管流量計等。</span> </p> <p> <span style="font-size:12px;">二次裝置為各種機械、電子、機電一體式差壓計,差壓變送器及流量顯示儀表。它已發(fā)展為三化(系列化、通用化及標準化)程度很高的、種類規(guī)格龐雜的一大類儀表,它既可測量流量參數(shù),也可測量其它參數(shù)(如壓力、物位、密度等)。</span><span

測量流體流量的儀表統(tǒng)稱為流量計或流量表．流量計是工業(yè)測量中重要的儀表之一．隨著工業(yè)生產(chǎn)的發(fā)展，對流量測量的準確度和范圍的要求越來越高，流量測量技術日新月異．為了適應各種用途，各種類型的流量計相繼問世。目前已投入使用的流量計已超過 100 種。 </p> <p> 每種產(chǎn)品都有它特定的適用性,也都有它的局限性。按測量原理分有力學原理、熱學原理、聲學原理、電學原理、光學原理、原子物理學原理等。 </p> <p> 檢測件又可按其標準化程度分為二大類:標準的和非標準的。 </p> <p> 所謂標準檢測件是只要按照標準文件設計、制造、安裝和使用,無須經(jīng)實流標定即可確定其流量值和估算測量誤差。 </p> <p> <span

電磁流量計的安裝與調(diào)試比其它流量計復雜，且要求更嚴格。變送器和轉換器必須配套使用，兩者之間不能用兩種不同型號的儀表配用。在安裝變送器時，從安裝地點的選擇到具體的安裝調(diào)試，必須嚴格按照產(chǎn)品說明書要求進行。安裝地點不能有振動，不能有強磁場。在安裝時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流體等電位。在使用時，必須排盡測量管中存留的氣體，否則會造成較大的測量誤差。 </p> <p> 電磁流量計用來測量帶有污垢的粘性液體時，粘性物或沉淀物附著在測量管內(nèi)壁或電極上，使變送器輸出電勢變化，帶來測量誤差，電極上污垢物達到一定厚度，可能導致儀表無法測量。污水流量計結構簡單、牢固可靠、使用壽命長。連云港液體渦輪流量計哪家比較好</p><p

style="font-size:12px;">渦輪流量計可水平、垂直安裝，垂直安裝時流體方向必須向上。液體應充滿管道，不得有氣泡。安裝時，液體流動方向應與傳感器外殼上指示流向的箭頭方向一致。安裝時必須使管道內(nèi)流體滿管，才能保證測量精細。 </span> <p> 流量計上游端至少應有10倍公稱通徑長度的直管段，下游端應不少于5倍公稱通徑的直管段，其內(nèi)壁應光滑清潔，無凹痕、積垢和起皮等缺陷。傳感器的管道軸心應與相鄰管道軸心對準，連接密封用的墊圈不得深入管道內(nèi)腔。不同情況下的直管段要求如下圖。 </p> <p> 同時在安裝時應避免管道內(nèi)產(chǎn)生氣泡，否則會影響測量的精度。 </p> <p> 威力巴流量計 </p> <p>
