智能型電磁流量計(jì)如果在日常使用過程中出現(xiàn)了一些問題，我們就要去認(rèn)真的去找原因。原因很多，主要有下面幾個(gè)方面： </p> <p> 一、使用場(chǎng)所的原因 </p> <p> 使用場(chǎng)所如果不太好，比如現(xiàn)場(chǎng)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(huì)使智能電磁流量計(jì)使用出現(xiàn)問題。 </p> <p> 三、測(cè)量介質(zhì)的原因 </p> <p> 如果所測(cè)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(cè)量介質(zhì)里面有許多氣泡，它就會(huì)地影響測(cè)量信號(hào)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(huì)積污垢，這樣也會(huì)影響電磁流量計(jì)的測(cè)量效果。 </p> <p> 五，福建長頸噴嘴流量計(jì)多少錢，福建長頸噴嘴流量計(jì)多少錢、電磁流量計(jì)的電源線，要做好防雷電的工作，福建長頸噴嘴流量計(jì)多少錢。特別是夏天，一定做注意這一點(diǎn)。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(duì)計(jì)量精度的影響。福建長頸噴嘴流量計(jì)多少錢</p><div
