style="text-indent:25px">流量計(jì)伴熱辦法：1、蒸汽伴熱辦法，即運(yùn)用管蒸汽暖氣保溫。冬天保溫送汽之前要查看一下蒸汽保溫管路是不是疏通或阻塞。較好的蒸汽是24小時(shí)通的，不要太熱，有時(shí)還要依據(jù)氣候溫度改動(dòng)來調(diào)整供保溫汽量，以避免溫度太高使變送器引壓管內(nèi)冷凝液汽化影響變送器作業(yè)或因溫度太低使變送器引壓管內(nèi)冷凝液冷凍影響變送器作業(yè)疏通。2、電加熱帶辦法，插入式流量計(jì)，電伴熱保溫技能是一種新式的由電能直接轉(zhuǎn)化為熱能的供暖技能。加裝保溫電纜，插入式流量計(jì)，將伴熱帶，纏繞在外表上，或粘在外表柜內(nèi)部（但要留意所用伴熱帶的長(zhǎng)度，插入式流量計(jì)，要經(jīng)濟(jì)適度）。轉(zhuǎn)子流量計(jì)中心線與鉛垂線間夾角一般不超過5度。插入式流量計(jì)</p><div

src="https://tyunfile.71360.com/UploadFile/yierdianzi/637407039080282827/1708933.png"></div><p style="text-indent:25px">在安裝和使用流量計(jì)的過程當(dāng)中，應(yīng)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(yīng)該要把流量計(jì)和電纜頭本來就有的一個(gè)保護(hù)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(jì)廠家強(qiáng)調(diào)尤其要注意使用完成之后，不可以等待并應(yīng)該馬上把它蓋起來，尤其是電磁流量計(jì)變送器也同樣的要做好清潔以及防潮的工作。做好對(duì)流量計(jì)的保護(hù)工作避免損傷，循環(huán)時(shí)禁止連接流量計(jì)，這樣做是為了避免在其中還有一些堅(jiān)硬的巖石會(huì)損傷流量計(jì)內(nèi)部的結(jié)構(gòu)，從而導(dǎo)致測(cè)量精度不準(zhǔn)。因此測(cè)量氣體流量計(jì)廠家提醒每次施工完成之后，要采取些措施保護(hù)流量計(jì)內(nèi)襯，并且一定要避免流量計(jì)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。插入式流量計(jì)容積式流量計(jì)，又稱定排量流量計(jì)，簡(jiǎn)稱PD流量計(jì)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="插入式流量計(jì),流量計(jì)"

style="text-indent:25px">孔板流量計(jì)工作原理：流體充滿管道，流經(jīng)管道內(nèi)的節(jié)流裝置時(shí)，流束會(huì)出現(xiàn)局部收縮，從而使流速增加，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)可以通過測(cè)量壓差來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。工作特點(diǎn)：①節(jié)流裝置結(jié)構(gòu)簡(jiǎn)單、牢固，性能穩(wěn)定可靠，使用期限長(zhǎng)，價(jià)格低廉;②應(yīng)用范圍廣，全部單相流皆可測(cè)量，部分混相流亦可應(yīng)用;③標(biāo)準(zhǔn)型節(jié)流裝置無須實(shí)流校準(zhǔn)，即可投用;④ 一體型孔板安裝更簡(jiǎn)單，無須引壓管，可直接接差壓變送器和壓力變送器。</p><p style="text-indent:25px">超聲波流量計(jì)的常見故障及處理情況：1、流速顯示不正常數(shù)據(jù)劇烈變化，可能是傳感器安裝在管道振動(dòng)大的地方或安裝在調(diào)節(jié)閥、泵、縮流孔的下游。處理方法: 將傳感器裝在遠(yuǎn)離振動(dòng)的地方或移至改變流態(tài)裝置的上游。2、讀數(shù)不正確。應(yīng)該是傳感器裝在水平管道的頂部或底部有沉淀物干擾超聲波信號(hào)。要么就是傳感器裝在水流向下的管道上管內(nèi)未充滿流體。處理方法：前者將傳感器裝在管道兩側(cè)、后者將傳感器裝在充滿流體的管段上。3、傳感器是好的,但流速低或沒有流速?？赡苁?A，由于管道內(nèi)的油漆、鐵銹未掃除干凈. 處理方法：重新掃除管道,安裝傳感器。B，管道面凹凸不平或安裝在焊接縫處。處理方法：將管道磨平或遠(yuǎn)離焊縫處安裝傳感器。C，管道圓度不好,內(nèi)表面不光滑,有管襯式結(jié)垢。處理方法：選擇鋼管等內(nèi)表面光滑管道材質(zhì)或襯的地方安裝傳感器。D，傳感器與管道耦合不好,耦合面有縫隙或氣泡。處理方法：重新安裝耦合劑。E，傳感器安裝在套管上,則會(huì)削弱超聲波信號(hào)。處理方法：將傳感器移到無套管的管段部位上。流量計(jì)每次使用完成之后，應(yīng)該要把流量計(jì)和電纜頭本來就有的一個(gè)保護(hù)的裝置蓋子蓋好做密封的包裝處理。</p><div

src="https://tyunfile.71360.com/UploadFile/yierdianzi/637407039036405821/5647925.png"></div><p style="text-indent:25px">熱式質(zhì)量流量計(jì)的優(yōu)點(diǎn)：1. 球閥安裝，安裝拆卸方便。并可以帶壓安裝。2. 基于金氏定律，直接測(cè)量質(zhì)量流量。測(cè)量值不受壓力和溫度影響。3. 響應(yīng)迅速。4.量程范圍大，管道式安裝小的可以測(cè)量8.8mm管道的流量，大的可以測(cè)到30。5. 插入式類型的流量計(jì)，一支流量計(jì)可以用于測(cè)量多種管徑。超聲波流量計(jì)是通過檢測(cè)流體流動(dòng)對(duì)超聲束（或超聲脈沖）的作用以測(cè)量流量的儀表。超聲流量計(jì)和電磁流量計(jì)一樣，因儀表流通通道未設(shè)置任何阻礙件，均屬無阻礙流量計(jì)，是適于解決流量測(cè)量困難問題的一類流量計(jì)，特別在大口徑流量測(cè)量方面有較突出的優(yōu)點(diǎn)，它是發(fā)展迅速的一類流量計(jì)之前列量計(jì)要盡量避開鐵磁性物體及具有強(qiáng)電磁場(chǎng)的設(shè)備。插入式流量計(jì)</p><p style="text-indent:25px">壓式流量計(jì)由一次裝置(檢測(cè)件）和二次裝置（差壓轉(zhuǎn)換器和流量顯示儀表）組成。插入式流量計(jì)</p><p style="text-indent:25px">電磁流量計(jì)的傳感器結(jié)構(gòu)簡(jiǎn)單，測(cè)量管內(nèi)沒有可動(dòng)部件，也沒有任何阻礙流體流動(dòng)的節(jié)流部件。所以當(dāng)流體通過流量計(jì)時(shí)不會(huì)引起任何附加的壓力損失，是流量計(jì)中運(yùn)行能耗較低的流量?jī)x表之一。、電磁流量計(jì)是一種體積流量測(cè)量?jī)x表，在測(cè)量過程中，它不受被測(cè)介質(zhì)的溫度、粘度、密度以電導(dǎo)率(在一定范圍)的影響。因此，電磁流量計(jì)只需經(jīng)水標(biāo)定后，就可心用來測(cè)量其它導(dǎo)電性液體的流量。電磁流量計(jì)的輸出只與被測(cè)介質(zhì)的平均流速成正比，而與對(duì)稱分布下的流動(dòng)狀態(tài)(層流或湍流)無關(guān)。所以電磁流量計(jì)的量程范圍極寬，其測(cè)量范圍度可達(dá)10：1的可運(yùn)行流量范圍。插入式流量計(jì)</p></p><br
