為了改善渦流與流場畸變的影響，流量計安裝的前、后直管段長度有一定要求，否則會影響測量精度（也可安裝整流器，盡量避免在靠近調(diào)節(jié)閥和半開閥門之后安裝）。 </p> <p> 2．對工藝管的要求: </p> <p> 流量計對安裝點的上、下游工藝管有一定的要求，否則影響測量精度。 </p> <p> a．上、下游工藝管的內(nèi)徑與傳感器的內(nèi)徑相同，并應(yīng)滿足：0.98DN≤D≤1.05DN（式中DN：傳感器內(nèi)徑，D：工藝管內(nèi)徑）; </p> <p> b．工藝管與傳感器必須同心，同軸偏差應(yīng)不大于0.05DN. </p> <p> 3．旁通管的要求: </p> <p> 為了方便檢修流量計，比較好為流量計安裝旁通管，另外，對重污染流體及流量計需清而流體不能停止的，必須安裝旁通管。 </p> <p> a．方便流量計的檢修; </p> <p> b．對重污染流體必須安裝; </p> <p> c．流體不能停止而流量計需清洗. 微小流量計哪家好在工業(yè)現(xiàn)場，測量流體流量的儀表統(tǒng)稱為流量計或流量表。是工業(yè)測量中重要的儀表之一。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="熱式流量計型號,流量計"

電極：其作用是引出和被測量成正比的感應(yīng)電勢信號。電極一般用非導(dǎo)磁的不銹鋼制成，且被要求與襯里齊平，以便流體通過時不受阻礙。它的安裝位置宜在管道的垂直方向，以防止沉淀物堆積在其上面而影響測量精度。 </p> <p> 外殼：應(yīng)用鐵磁材料制成，是分配制度勵磁線圈的外罩，并隔離外磁場的干擾。 </p> <p> 襯里：在測量導(dǎo)管的內(nèi)側(cè)及法蘭密封面上，有一層完整的電絕緣襯里。它直接接觸被測液體，其作用是增加測量導(dǎo)管的耐腐蝕性，防止感應(yīng)電勢被金屬測量導(dǎo)管管壁短路。襯里材料多為耐腐蝕、耐高溫、耐磨的聚四氟乙烯塑料、陶瓷等。 </p> <p> 轉(zhuǎn)換器：由液體流動產(chǎn)生的感應(yīng)電勢信號十分微弱，受各種干擾因素的影響很大，轉(zhuǎn)換器的作用就是將感應(yīng)電勢信號放大并轉(zhuǎn)換成統(tǒng)一的標(biāo)準(zhǔn)信號并yizhi主要的干擾信號。其任務(wù)是把電極檢測到的感應(yīng)電勢信號Ex經(jīng)放大轉(zhuǎn)換成統(tǒng)一的標(biāo)準(zhǔn)直流信號。 </p><p> 高溫型（80度至500度）、常溫型（-20度至70度）、低溫型（-20至-200度）流量計的安裝： </p> <p> a、常溫型、低溫型、高溫型流量計視不同工況采用水平、垂直或倒置式安裝（以出廠校驗單為準(zhǔn)）；b、介質(zhì)工作溫度在300度以上時，用戶應(yīng)對流量計殼體采取隔熱措施防止熱輻射損壞表頭(表頭工作溫度為-30至70度)，同理工作溫度-100度以下的介質(zhì)，也要采取防凍措施；c、為保證流量計準(zhǔn)確計量，要求設(shè)置前后直管段；）d、為保證流量計在檢查及更換時不影響系統(tǒng)工作，應(yīng)盡量設(shè)置旁通閥（3）及切斷閥（1、2）；e、因工藝需要可采用垂直安裝，被測介質(zhì)流向可由下至上，也可由上至下，但訂購時應(yīng)向供貨方說明。浮子流量計可用于較低雷諾數(shù)，選用粘度不敏感形狀的浮子，流通環(huán)隙處雷諾數(shù)只要大于40或500。</p><div

差壓式孔板流量計是一款流量測量儀表，主要應(yīng)用于液體、氣體流量測量，像蒸汽流量測量就是一個典型的測量工況，蒸汽在流量測量的過程中，由于自身溫度較高，測量難度大一般的流量計都無法勝任，而差壓式孔板流量計就可以有效的解決。差壓式孔板流量計的應(yīng)用領(lǐng)域非常廣，測量精度可達±0.5%，溫度可達700度，并且量程比為10：1，主要在氣體、蒸汽、液體的流量測量領(lǐng)域應(yīng)用較多，差壓式孔板流量計還有一個優(yōu)勢就是安裝方便，并且也不需要維護。測量蒸汽只能用專門設(shè)計的金屬管浮子流量計或在標(biāo)準(zhǔn)型儀表上加裝附加構(gòu)件。熱式流量計型號</p><p style="text-indent:25px">流量計又分為有差壓式流量計、容積流量計、電磁流量計、超聲波流量計、渦輪流量計和渦街流量計等等。熱式流量計型號</p><p> 電磁流量計如何抗干擾？在測量紙漿/礦漿等大干擾信號應(yīng)用時，選用8707高信號流量管，可以提高信號強度智能電磁流量計AFLD是采用全智能化原理設(shè)計的，與原來國內(nèi)一些企業(yè)生產(chǎn)的老式或假式智能化的電磁流量計在計量精度，功能，可靠性以及使用壽命上有非常大區(qū)別。電磁流量計的使用壽命應(yīng)該是在10-20年以上，所以我們在設(shè)計時就充分考慮廠到這一點，從傳感器到轉(zhuǎn)換器的每一個細節(jié)我們都非常仔細，從設(shè)計，選材，工藝，生產(chǎn)，測試等每一個環(huán)節(jié)我們都非常講究，自行設(shè)計定制國內(nèi)目前zui先進的**與電磁流量計的生產(chǎn)流水線，切實保證產(chǎn)品的長期質(zhì)量。插入式電磁流量計由插入式電磁流量傳感器(簡稱傳感器）和電磁流量轉(zhuǎn)換器(簡稱轉(zhuǎn)換器）配套組成(簡稱流量計)。是用來測量管道內(nèi)各種導(dǎo)電液體體積流量的儀表。插入式電磁流量計用來測量自來水、鋼鐵、石油、化工、電力、工業(yè)、水利等部門的導(dǎo)電流體流量，亦可測量酸、堿、鹽等腐蝕性導(dǎo)電液體。熱式流量計型號</p><p
