style="text-indent:25px">在安裝和使用流量計的過程當中，應該要保持電纜接頭足夠的清潔和干燥并且做好防水防潮的措施，每次使用完成之后，應該要把流量計和電纜頭本來就有的一個保護的裝置蓋子蓋好做密封的包裝處理，或者使用防水塑料包好。循環(huán)水管道流量計廠家強調(diào)尤其要注意使用完成之后，不可以等待并應該馬上把它蓋起來，尤其是電磁流量計變送器也同樣的要做好清潔以及防潮的工作。做好對流量計的保護工作避免損傷，循環(huán)時禁止連接流量計，這樣做是為了避免在其中還有一些堅硬的巖石會損傷流量計內(nèi)部的結(jié)構(gòu)，從而導致測量精度不準。因此測量氣體流量計廠家提醒每次施工完成之后，要采取些措施保護流量計內(nèi)襯，并且一定要避免流量計的內(nèi)襯，接觸到油類物質(zhì)以免影響到絕緣內(nèi)襯，不可以讓硬物劃傷挫傷，以及破壞表面的光潔度。非接觸式流量計批發(fā)電磁流量計的測量原理不依賴流量的特性。</p><div

style="text-indent:25px">轉(zhuǎn)子流量計儀表安裝方向：大部分轉(zhuǎn)子流量計必須垂直安裝在無振動的管道上，不應有明顯的傾斜，流體自下而上流過儀表。轉(zhuǎn)子流量計中心線與鉛垂線間夾角一般不超過5度，高精度(1.5級以上)儀表θ≤20°。如果θ＝12°則會產(chǎn)生1％附加誤差。儀表無嚴格上游直管段長度要求，但也有制造廠要求(2-5)D長度的，實際上必要性不大。轉(zhuǎn)子流量計擴大范圍度的安裝：如果測量要求的流量范圍度寬，范圍度超過10時，可以在一臺儀表內(nèi)放兩只不同形狀和重量的浮子，小流量時取輕浮子讀數(shù)，浮子到頂部后取重浮子讀數(shù)，范圍度可擴大到50-100。</p><p

超聲波流量計可以測量各種液體和污水流量。(5) 超聲波流量計測量的體積流量不受被測流體的溫度、壓力、粘度及密度等熱物性參數(shù)的影響?？梢宰龀晒潭ㄊ胶捅銛y式兩種形式。流量計又分為有差壓式流量計、轉(zhuǎn)子流量計、容積流量計、電磁流量計、超聲波流量計等。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">渦輪流量計屬于速度式流量計的一種，它是以測量管道中燃氣流動的速度來推算氣體的流量。為了保證測量的精確度，流入渦輪流量計內(nèi)的燃氣必須為典型的層流或紊流分布，這就要求流量計的前端及后端都有足夠長的直管段以使氣流穩(wěn)定。一般我們要求前端直管段長度為3d（即3倍管徑），后端為2d，在此范圍內(nèi)不應有彎頭、三通、截止閥等管件。由于流量計安裝空間受限或施工經(jīng)驗不足，施工單位往往沒有按上述要求去做，這樣的渦輪流量計是不能交付使用的。在設備安裝前應該仔細查看安裝說明書，了解各種設備的特殊安裝要求，總結(jié)經(jīng)驗，避免不應有的失誤。轉(zhuǎn)子流量計流量值應作必要的換算。非接觸式流量計批發(fā)</p><p style="text-indent:25px">對于渦街流量計來說，測量氣體流量時，若被測氣體含有少量的液體，流量計應安裝在管線的較高處。非接觸式流量計批發(fā)</p><p style="text-indent:25px">渦輪流量計的安裝要點：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，才能保證測量準確。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。非接觸式流量計批發(fā)</p><p
