SKLD係列插入式電磁流量計用來測量導電的液體,特別適用於大口徑的管道測量。其原理是基於法拉第電磁感應定律。流量計的(de)測(ce)量(liang)管(guan)是(shi)一(yi)內(nei)襯(chen)絕(jue)緣(yuan)材(cai)料(liao)的(de)非(fei)導(dao)磁(ci)合(he)金(jin)短(duan)管(guan)。兩(liang)隻(zhi)電(dian)極(ji)沿(yan)管(guan)徑(jing)方(fang)向(xiang)穿(chuan)通(tong)管(guan)壁(bi)固(gu)定(ding)在(zai)測(ce)量(liang)管(guan)上(shang)。其(qi)電(dian)極(ji)頭(tou)與(yu)襯(chen)裏(li)內(nei)表(biao)麵(mian)基(ji)本(ben)齊(qi)平(ping)。勵(li)磁(ci)線(xian)圈(quan)由(you)雙(shuang)方(fang)波(bo)脈(mai)衝(chong)勵(li)磁(ci)時(shi)
，將(jiang)在(zai)與(yu)測(ce)量(liang)管(guan)軸(zhou)線(xian)垂(chui)直(zhi)的(de)方(fang)向(xiang)上(shang)產(chan)生(sheng)一(yi)磁(ci)通(tong)量(liang)密(mi)度(du)為(wei)B的工作磁場。此時，如果具有一定電導率的流體流經測量管。將切割磁力線感應出電動勢E。電動勢E正比於磁通量密度B，測量管內徑d與平均流速v的乘積。電動勢E(流量信號)由(you)電(dian)極(ji)檢(jian)出(chu)並(bing)通(tong)過(guo)電(dian)纜(lan)送(song)至(zhi)轉(zhuan)換(huan)器(qi)。轉(zhuan)化(hua)器(qi)將(jiang)流(liu)量(liang)信(xin)號(hao)放(fang)大(da)處(chu)理(li)後(hou)
