JL-LDE污水流量計 工作原理：

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)流量(liang)(liang)計(ji)的工作原理是(shi)基(ji)于法拉(la)第電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)感應定(ding)律。在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)流量(liang)(liang)計(ji)中(zhong)，測(ce)量(liang)(liang)管(guan)內的導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)介(jie)質(zhi)相當于法拉(la)第試驗中(zhong)的導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)金屬桿，上下(xia)兩端的兩個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)線圈產(chan)生(sheng)恒定(ding)磁(ci)(ci)場。當有導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)介(jie)質(zhi)流過(guo)時，則會產(chan)生(sheng)感應電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓。管(guan)道內部(bu)的兩個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)測(ce)量(liang)(liang)產(chan)生(sheng)的感應電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓。測(ce)量(liang)(liang)管(guan)道通過(guo)不導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的內襯（橡膠，特氟隆(long)等）實現(xian)與流體和測(ce)量(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)隔離(li)，如圖所示。
