智能電磁流量計(jì)是60年代興起的一種流量儀表，因?yàn)樗歉鶕?jù)傳統(tǒng)的物理電磁感應(yīng)原理制成的，擁有著非常獨(dú)特的特點(diǎn)，所以被的應(yīng)用到生產(chǎn)的各個領(lǐng)域，它的工作原理非常的簡單，如果發(fā)生故障，維修起來也非常的方便，適合所有的工廠使用。 </p> <p> 1、連續(xù)浸水防護(hù)等級IP68型：給排水、污水處理安裝地大多為地下管線的害井內(nèi)，雨水、地下滲水常使流量計(jì)浸于水中，或冬季結(jié)露，降低接線端子和線圈的絕緣強(qiáng)度，影響產(chǎn)品性能并縮短流量計(jì)使用壽命。 </p> <p> 2、潛水型：用于明渠流量測量，替代傳統(tǒng)堪板式流量計(jì)。 </p> <p> 3、防爆型：使用于在具有可性氣體環(huán)境條件下，如化工、煤礦、油田使用。 </p> <p> 4、衛(wèi)生型：容易拆卸沖洗消毒，可快速安裝，適用于食品、醫(yī)藥部門使用。 </p> <p> 5、高壓型：對于石油化工的鉆井循環(huán)泥漿、固井水泥漿、采油工藝的高壓注水等。 </p> <p> 6、一般型：適用于除上所述的，一般的用途。山東孔板流量計(jì)價格流量計(jì)有渦輪流量計(jì)、渦街流量計(jì)、電磁流量計(jì)、多普勒超聲波流量計(jì)、熱線測速流量計(jì)；</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

一、使用場所的原因 </p> <p> 使用場所如果不太好，比如現(xiàn)場有一些干擾，我們就要想辦法來解決這些問題。比如在接地上用單一地接地，或用傳感器和管道進(jìn)行不導(dǎo)電的辦法；還有就是用屏蔽線給予保護(hù)。 </p> <p> 二、裝配程序的原因 </p> <p> 比如有的用戶把智能電磁流量計(jì)在容易有空氣的高處，或者安裝在不經(jīng)常是滿管的地方，或者安裝在流體從上到下的堅(jiān)著的管子上，這些都會使智能電磁流量計(jì)使用出現(xiàn)問題。 </p> <p> 三、測量介質(zhì)的原因 </p> <p> 如果所測量的介質(zhì)不是單單地導(dǎo)電液體，而是液氣混合，也就是說測量介質(zhì)里面有許多氣泡，它就會地影響測量信號輸出地穩(wěn)定性。 </p> <p> <br /> </p> <p> 四、長期使用了的智能電磁流量計(jì)的內(nèi)管里會積污垢，這樣也會影響電磁流量計(jì)的測量效果。 </p> <p> 五、電磁流量計(jì)的電源線，要做好防雷電的工作。特別是夏天，一定做注意這一點(diǎn)。 </p><p> 孔板流量計(jì)安裝要求1、孔板在安裝前應(yīng)檢查節(jié)流裝置編號和尺寸是否符合管道安裝位置的要求。2、新裝管路系統(tǒng)，必須在管道沖洗和掃線后再進(jìn)行孔板的安裝。3、注意孔板安裝方向“+”號應(yīng)該向著流束。4、孔板中心應(yīng)該和管道中心線相重合，同心度誤差不得超過(1/β-1)的數(shù)值。5、孔板在管道中安裝時應(yīng)保證其端面與管道軸線垂直、垂直度誤差不得超過±1°。6、夾緊孔板用的密封墊片(包括環(huán)室與法蘭、環(huán)室與孔板間)，在夾緊后，不得突入管道內(nèi)壁。7、孔板安裝處必須嚴(yán)密，不允許有泄漏現(xiàn)象存在。因此，安裝工作必須在管道試壓前進(jìn)行。8、導(dǎo)壓管應(yīng)垂直或傾斜敷設(shè)，其傾度不得小于1:12。粘度較高的流體，其傾斜度還應(yīng)增大。當(dāng)差壓訊號傳送距離大于3米時，導(dǎo)壓管應(yīng)分段傾斜，并在各高點(diǎn)和低點(diǎn)分別裝設(shè)集氣器和沉降器。9、為了避免差壓訊號傳送失真，正負(fù)導(dǎo)壓管應(yīng)盡量靠近敷設(shè)，嚴(yán)寒地區(qū)還應(yīng)采取防凍措施?？刹捎秒姛峄蛘魵獗?，但要防止被測介質(zhì)過熱汽化和在導(dǎo)壓管中產(chǎn)生氣體造成假差壓。10、孔板安裝在垂直主管道上時，取壓口位置，可在取壓裝置的平面上任意選擇?？装灏惭b在水平或傾斜的主管道內(nèi)，取壓口位置如圖四所示。11、導(dǎo)壓管按被測介質(zhì)的性質(zhì)而選擇耐壓、耐腐蝕的材料制造。電磁流量計(jì)所測得體積流量實(shí)際上不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的明顯影響；</p><div

</p> <p> 電磁流量計(jì)是通過測量導(dǎo)電液體的速度確定工作狀態(tài)下的體積流量。按照計(jì)量要求，對于液態(tài)介質(zhì)，應(yīng)測量質(zhì)量流量，測量介質(zhì)流量應(yīng)涉及到流體的密度，不同流體介質(zhì)具有不同的密度，而且隨溫度變化。如果電磁流量計(jì)轉(zhuǎn)換器不考慮流體密度，*給出常溫狀態(tài)下的體積流量是不合適的。因質(zhì)量流量計(jì)是依據(jù)科氏力原理工作的，為避免重力對計(jì)量精度的影響。山東孔板流量計(jì)價格</p><p
