二,工作原理Work Principal
電磁流量計(jì)所依據(jù)的基本理論是法拉第電磁感應(yīng)定律,可測量管內(nèi)流動(dòng)的導(dǎo)電流體的體積,如圖1所示,導(dǎo)電流體流動(dòng)方向與電磁場的方向垂直,在導(dǎo)管垂直方向施加一個(gè)交變的磁場并在有緣襯里的導(dǎo)管內(nèi)壁兩側(cè)安裝一對電,兩電的連線即與導(dǎo)管軸線垂直,又與磁場方向垂直,當(dāng)導(dǎo)電液體流經(jīng)導(dǎo)管時(shí),因切割磁力線,兩個(gè)電上就產(chǎn)生感應(yīng)電動(dòng)勢UE。
The basic theory is Faraday ekctromagneti, when the conductor cut
the magnet, when the conduct get the moving eloctnomtxis a (twee. According
this principal, can be test the volume of the liquid, such a picture 1. the
direction of current is vertical with the magnet direction, the sensor pole
vertical with the magnet way and current way, when the conduct liquid flow
the pipe, because cut the magnet line, the two head of the pole will produce
the electromotive force UE.
