B、不能安裝在大型變壓器、電動機、機泵等產(chǎn)生較大磁場的設備附近，以免受到電磁場的干擾; </p> <p> C、傳感器與管道連接時應保證滿管運行，山東液體渦輪流量計廠家，比較好垂直安裝; </p> <p> D，山東液體渦輪流量計廠家、變送器外殼接地與就近接地網(wǎng)連接即可;屏蔽電纜(分體式)按說明書連接，信號電纜(至系統(tǒng))進行屏蔽層系統(tǒng)處單端接地;測量傳感器與管道連接的短路環(huán)需要接地，接地電阻應小于10歐姆，不能與電氣接地共用; </p> <p> E，山東液體渦輪流量計廠家、流量計傳感器上游也應該有一定的直管段，一般在5D~10D。 </p> <p>

電磁流量計有一系列優(yōu)良特性,可以解決其它流量計不易應用的問題,如臟污流、腐蝕流的測量。變送器的測量信號為很小的毫伏級電勢信號，除流量信號外，還夾雜一些與流量無關的信號，如同相電壓、正交電壓及共模電壓等。為了準確測量流量，必須消除各種干擾信號，有效放大流量信號。應該提高流量轉(zhuǎn)換器的性能，比較好采用微處理機型的轉(zhuǎn)換器，用它來控制勵磁電壓，按被測流體性質(zhì)選擇勵磁方式和頻率，可以排除同相干擾和正交干擾。但改進的儀表結構復雜，成本較高。河北熱式氣體質(zhì)量流量計生產(chǎn)廠家電磁流量計的常規(guī)直管段要求是**D后5D，在有彎管、閥門的情況分別有不同的要求。</p><div

標準節(jié)流件是全世界通用的，并得到了國際標準組織的認可，無需實流校準，即可投用，在流量計中亦是的。結構易于復制，簡單、牢固、性能穩(wěn)定可靠、價格低廉；應用范圍廣，包括全部單相流體（液、氣、蒸汽）、部分混相流，一般生產(chǎn)過程的管徑、工作狀態(tài)(溫度、壓力)皆有產(chǎn)品。檢測件和差壓顯示儀表可分開不同廠家生產(chǎn)，便與專業(yè)化規(guī)模生產(chǎn)； </p> <p> 缺點： </p> <p> 測量的重復性、精確度在流量計中屬于中等水平，由于眾多因素的影響錯綜復雜，精確度難于提高。范圍度窄，由于流量系數(shù)與雷諾數(shù)有關,一般范圍度* 3∶1 ～ 4∶1。有較長的直管段長度要求，一般難于滿足。尤其對較大管徑，問題更加突出；壓力損失大；通常為維持一臺孔板流量計正常運行，水泵需要附加動力克服孔板的壓力損失。該附加耗電量可直接由 </p><p> 流動本身的脈動，如擬裝儀表位置的上游有往復泵或調(diào)節(jié)閥，或下游有大負荷變化等，應改換測量位置或在管道系統(tǒng)予以補救改進，如加裝緩沖罐;若是儀表自身的振蕩，如測量時氣體壓力過低，儀表上游閥門未全開，調(diào)節(jié)閥未裝在儀表下游等原因，應針對性改進克服，或改選用有阻尼裝置的儀表。5、轉(zhuǎn)子流量計要排盡液體用儀表內(nèi)氣體進出口不在直線的角型金屬轉(zhuǎn)子流量計，用于液體時注意外傳浮子位移的引申套管內(nèi)是否殘留空氣，必須排盡;若液體含有微小氣泡流動時極易積聚在套管內(nèi)，更應定時排氣。這點對小口徑儀表更為重要，否則影響流量示值明顯。6、轉(zhuǎn)子流量計流量值應作必要換算若非按使用密度、粘度等介質(zhì)參數(shù)向轉(zhuǎn)子流量計生產(chǎn)廠家專門訂制的儀表，液體用儀表通常以水標定流量，氣體儀表用空氣標定，定值在工程標準狀態(tài)。使用條件的流體密度、氣體壓力溫度與標定不一致時，要做必要換算。換算公式和方法轉(zhuǎn)子流量計的制造廠使用說明書中都有詳述。測量水蒸汽流量時，應用保溫材料一同包扎，必須時（如氣溫0℃以下）加伴熱管防止結冰。</p><div

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、下游兩側產(chǎn)生靜壓力差。在已知有關參數(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出差壓與流量之間的關系而求得流量。<span style="font-size:12px;">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.</span>

</p> <p> 優(yōu)點: </p> <p> （1）球閥安裝，安裝拆卸方便。并可以帶壓安裝。 </p> <p> （2）基于金氏定律，直接測量質(zhì)量流量。測量值不受壓力和溫度影響。 </p> <p> （3）響應迅速。 </p> <p> （4）量程范圍大，管道式安裝小可以測量8.8mm管道的流量，比較大可以測到30’’ </p> <p> （5）插入式類型的流量計，一支流量計可以用于測量多種管徑。 </p> <p> 缺點: </p> <p> （1）精度不及其他類型流量計，一般為3％。 </p> <p> （2）適用范圍窄，只能用于測量干燥的非性的氣體，如壓縮空氣、氮氣、氬氣及其他中性氣體。山東液體渦輪流量計廠家</p><p
