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行不導(dǎo)電的辦法；還有就是用屏蔽線給予保護。 </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著的管子上，這些都會使智能電磁流量計使用出現(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的內(nèi)管里會積污垢，這樣也會影響電磁流量計的測量效果。 </p> <p> 五、電磁流量計的電源線，要做好防雷電的工作。特別是夏天，一定做注意這一點。淮安液體渦輪流量計廠家哪家好電磁流量計所測得體積流量實際上不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的明顯影響；</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

（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(yīng)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。 </p><p>

渦街流量計工作狀態(tài)下的體積流量不受被測流體溫度、壓力、密度等熱工參數(shù)的影響，但液體或蒸汽的**終測量結(jié)果應(yīng)是質(zhì)量流量，對于氣體，**終測量結(jié)果應(yīng)是標(biāo)準(zhǔn)體積流量。質(zhì)量流量或標(biāo)準(zhǔn)體積流量都必須通過流體密度進行換算，必須考慮流體工況變化引起的流體密度變化。 </p> <p> 造成流量測量誤差的因素主要有：管道流速不均造成的測量誤差；不能準(zhǔn)確確定流體工況變化時的介質(zhì)密度；將濕飽和蒸汽假設(shè)成干飽和蒸汽進行測量。這些誤差如果不加以限制或消除，渦街流量計的總測量誤差會很大。電磁流量計的電源線，要做好防雷電的工作。特別是夏天，一定做注意這一點。山東氣體渦輪流量計供貨廠</p><p

質(zhì)量流量計安裝要求1、安裝位置的選擇應(yīng)避免電磁干擾。傳感器、變送器的安裝位置以及電纜鋪設(shè)應(yīng)盡量遠離易產(chǎn)生強電磁場的設(shè)備，如大功率馬達、變壓器設(shè)施、變頻設(shè)備等。2、質(zhì)量流量傳感器安裝應(yīng)使傳感器流向標(biāo)識與流體流向一致。并使箭頭指向與變送器內(nèi)部組態(tài)的流量方向一致。(注：質(zhì)量流量計可以雙向使用。如果安裝方向與實際流向相反，修改變送器內(nèi)的流向組態(tài)即可。)3、質(zhì)量流量計是根據(jù)測量管振動原理測量的流量儀表，因此傳感器安裝時應(yīng)考慮在兩側(cè)的工藝管道近法蘭處(約2～10倍管徑處)做堅固的支撐，避免儀表及相關(guān)管路產(chǎn)生震動。若強烈的管道振動不可避免時，建議用柔性管將管道系統(tǒng)與儀表傳感器隔離。4、因質(zhì)量流量計是依據(jù)科氏力原理工作的，為避免重力對計量精度的影響。質(zhì)量流量計的測量管無論是向上還是向下安裝，都要盡量使測量管與地平面保持垂直或水平。5、安裝時連接法蘭面應(yīng)相互平行，應(yīng)使兩個法蘭的中心位于同一軸線避免產(chǎn)生附加應(yīng)力。嚴禁用傳感器硬行拉直上、下游工藝管道，否則將影響測量甚至損壞傳感器。6、在傳感器的上、下游管道上，建議安裝截止閥及旁路以方便調(diào)零、日常維護及確保傳感器在不工作時亦可處于滿管狀態(tài)。孔板流量計廠家哪家好</p><p
