智能型電磁流量計(jì)如果在日常使用過(guò)程中出現(xiàn)了一些問(wèn)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(lái)解決這些問(wèn)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，湖南金屬轉(zhuǎn)子流量計(jì)生產(chǎn)廠家，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(wèn)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(shuō)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(zhǎng)期使用了的智能電磁流量計(jì)的內(nèi)管里會(huì)積污垢，湖南金屬轉(zhuǎn)子流量計(jì)生產(chǎn)廠家，這樣也會(huì)影響電磁流量計(jì)的測(cè)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)，湖南金屬轉(zhuǎn)子流量計(jì)生產(chǎn)廠家。孔板流量計(jì)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；湖南金屬轉(zhuǎn)子流量計(jì)生產(chǎn)廠家</p><div style="width:100%;text-align:

關(guān)于超聲波流量計(jì)固定式和便攜式有什么不同 </p> <p> （1）合適使用的場(chǎng)合不一樣 </p> <p> 固定式超聲波流量計(jì)用于安裝在某一固定方位，對(duì)某一特定管道內(nèi)流體的流量進(jìn)行長(zhǎng)時(shí)間不間斷的計(jì)量；便攜式超聲波流量計(jì)具有很大的機(jī)動(dòng)性，首要用于對(duì)不一樣管道的流體流量作臨時(shí)性丈量。 </p> <p> （2）供電方法不一樣 </p> <p> 固定式超聲波流量計(jì)要求長(zhǎng)時(shí)間接連運(yùn)轉(zhuǎn)，所以要運(yùn)用220V交流電源，便攜式超聲波流量計(jì)既能夠運(yùn)用現(xiàn)場(chǎng)的交流電源，也備有內(nèi)置充電電池，能夠接連作業(yè)5～10h［小時(shí)］，方便了不一樣場(chǎng)合臨時(shí)性流量丈量的需要。 </p> <p> （3）有些功用不一樣 </p> <p> 因定式超聲波流量計(jì)，通常都有4-20mA信號(hào)輸出等功用，供遠(yuǎn)傳顯現(xiàn)運(yùn)用，但其內(nèi)部只能存貯一條管道的參數(shù)；便攜式超聲波流量計(jì)**為了現(xiàn)場(chǎng)檢查當(dāng)時(shí)流量和短時(shí)間內(nèi)的累計(jì)流量，故一般無(wú)輸出信號(hào)功用，但為了方便丈量不一樣管道流量，它具有豐厚的儲(chǔ)存功用，能夠一起存貯數(shù)十條不一樣管道的參數(shù)，供隨時(shí)調(diào)出運(yùn)用。

為了智能電磁流量計(jì)能夠很好地正常使用，智能電磁流量計(jì)傳感器接地一定要安裝好。智能電磁流量計(jì)傳感器接地時(shí)，應(yīng)注意以下幾點(diǎn)： </p> <p> 1、傳感器、轉(zhuǎn)換器的接地在現(xiàn)場(chǎng)，去二次儀表的屏蔽層在控制室一側(cè)接地，切勿多端接地，以免因電位不同而引入干擾。 </p> <p> 2、傳感器安裝在金屬管道上，可將傳感器的接地導(dǎo)線按制造廠的要求連接在管道法蘭上，形成可靠的接地回路儀表的接地點(diǎn)應(yīng)是一個(gè)**的接地點(diǎn)，不可以共用其他電氣設(shè)備的接地。 </p> <p> 3、傳感器的測(cè)量管、外殼、屏蔽線、轉(zhuǎn)換器及二次儀表都要接地。 </p> <p> 4、傳感器、轉(zhuǎn)換器應(yīng)單獨(dú)接地，不要連在電動(dòng)機(jī)、工藝管道上，接地電阻應(yīng)小于10歐姆。 </p><p> 電磁流量計(jì) (EMF) </p> <p> 電磁流量計(jì)是根據(jù)法拉弟電磁感應(yīng)定律制成的一種測(cè)量導(dǎo)電性液體的儀表。 </p> <p> 電磁流量計(jì)有一系列優(yōu)良特性,可以解決其它流量計(jì)不易應(yīng)用的問(wèn)題,如臟污流、腐蝕流的測(cè)量。 </p> <p> 70、80 年代電磁流量在技術(shù)上有重大突破,使它成為應(yīng)用的一類流量計(jì),在流量?jī)x表中其使用量百分?jǐn)?shù)不斷上升。 </p> <p> 優(yōu)點(diǎn): </p> <p> (1)測(cè)量通道是段光滑直管,不會(huì)阻塞,適用于測(cè)量含固體顆粒的液固二相流體,如紙漿、泥漿、污水等; </p> <p> (2)不產(chǎn)生流量檢測(cè)所造成的壓力損失,節(jié)能效果好; </p> <p> (3)所測(cè)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> <p> <span style="font-size:12px;">(4)流量范圍大,口徑范圍寬;</span> </p> <p> (5)可應(yīng)用腐蝕性流體。智能電磁流量計(jì)在使用時(shí)我們要求被測(cè)介質(zhì)必須是地電位，一般都是通過(guò)管道或法蘭接地；</p><div style="width:100%;text-align: center;"><img
