詳細(xì)介紹
E+H電磁流量計(jì)是由直接接觸管道介質(zhì)的傳感器和上端信號(hào)轉(zhuǎn)換器兩部分構(gòu)成。它是基于法拉第電磁感應(yīng)定律工作的,用來(lái)測(cè)量電導(dǎo)率大于5μs/cm的導(dǎo)電液體的流量,是一種測(cè)量導(dǎo)電介質(zhì)流量的儀表。除了可以測(cè)量一般導(dǎo)電液體的流量外,還可以用于測(cè)量強(qiáng)酸、強(qiáng)堿等強(qiáng)腐蝕性液體和均勻含有液固兩相懸浮的液體,如泥漿、礦漿、紙漿等。 電磁流量計(jì)及檢定合格證
E+H電磁流量計(jì)特別設(shè)計(jì)了帶背光寬溫的中文液晶顯示器,功能齊全實(shí)用、顯示直觀、操作使用方便,可以減少其他電磁流量計(jì)英文菜單所帶來(lái)的不便。另外我們*設(shè)計(jì)4-6多電極結(jié)構(gòu),進(jìn)一步保證了測(cè)量精度并且任何時(shí)候無(wú)需接地環(huán),減輕了儀表體積和安裝維護(hù)的麻煩?!‰姶帕髁坑?jì)在滿足現(xiàn)場(chǎng)顯示的同時(shí),還可以輸出4~20mA電流信號(hào)供記錄、調(diào)節(jié)和控制用,現(xiàn)已廣泛地應(yīng)用于化工、環(huán)保、冶金、醫(yī)藥、造紙、給排水等工業(yè)技術(shù)和管理部門。
e+h電磁流量計(jì)的工作原理是基于法拉第電磁感應(yīng)定律。在電磁流量計(jì)中,測(cè)量管內(nèi)的導(dǎo)電介質(zhì)相當(dāng)于法 拉第試驗(yàn)中的導(dǎo)電金屬桿,上下兩端的兩個(gè)電磁線圈產(chǎn)生恒定磁場(chǎng)。當(dāng)有導(dǎo)電介質(zhì)流過時(shí),則會(huì)產(chǎn)生感應(yīng)電壓。管道內(nèi)部的兩個(gè)電極測(cè)量產(chǎn)生的感應(yīng)電壓。測(cè)量管道通過不導(dǎo)電的內(nèi)襯(橡膠,特氟隆等)實(shí)現(xiàn)與流體和測(cè)量電極的電磁隔離。

E+H電磁流量計(jì)測(cè)量原理,E+H電磁流量計(jì)工作原理,E+H電磁流量計(jì)選型 E+H電磁流量計(jì)測(cè)量原理:根據(jù)法拉第電磁感應(yīng)定律,在磁感應(yīng)強(qiáng)度為B的均勻磁場(chǎng)中,垂直于磁場(chǎng)方向放一個(gè)內(nèi)徑為D的不導(dǎo)磁管道,當(dāng)導(dǎo)電液體在管道中以流速v流動(dòng)時(shí),導(dǎo)電流體就切割磁力線.如果在管道截面上垂直于磁場(chǎng)的直徑兩端安裝一對(duì)電極則可以證明,只要管道內(nèi)流速分布為軸對(duì)稱分布,兩電極之間產(chǎn)生感生電動(dòng)勢(shì):
e=KBDv (3-36)
式中,v為管道截面上的平均流速,k為儀表常數(shù)。由此可得管道的體積流量為:
qv= πeD/4KB (3-37)
由上式可見,體積流量qv與感應(yīng)電動(dòng)勢(shì)e和測(cè)量管內(nèi)徑D成線性關(guān)系,與磁場(chǎng)的磁感應(yīng)強(qiáng)度B成反比,與其它物理參數(shù)無(wú)關(guān).這就是電磁流量計(jì)的測(cè)量原理.
需要說明的是,要使式(3—37)嚴(yán)格成立,必須使電磁流量計(jì)測(cè)量條件滿足下列假定:
①磁場(chǎng)是均勻分布的恒定磁場(chǎng);
②被測(cè)流體的流速軸對(duì)稱分布;
③被測(cè)液體是非磁性的;
④被測(cè)液體的電導(dǎo)率均勻且各向同性。
