分體式電磁流量計(jì)是一種根據(jù)法拉第電磁感應(yīng)定律來(lái)測(cè)量管內(nèi)導(dǎo)電介質(zhì)體積流量的感應(yīng)式儀表,采用單片機(jī)嵌入式技術(shù),實(shí)現(xiàn)數(shù)字勵(lì)磁,同時(shí)在電磁流量計(jì)上采用CAN現(xiàn)場(chǎng)總線,屬國(guó)內(nèi)開創(chuàng),技術(shù)達(dá)到國(guó)內(nèi)**水平。
分體式電磁流量計(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。
電磁流量計(jì)除可測(cè)量一般導(dǎo)電液體的流量外,還可測(cè)量液固兩相流,高粘度液流及鹽類、強(qiáng)酸、強(qiáng)堿液體的體積流量。

量程范圍確認(rèn)
一般工業(yè)用電磁流量計(jì)被測(cè)介質(zhì)流速以2~4m/s為宜,在特殊情況下,*低流速應(yīng)不小于0.2m/s,*高應(yīng)不大于8m/s。若介質(zhì)中含有固體顆粒,常用流速應(yīng)小于3m/s,防止襯里和電極的過(guò)分磨擦;對(duì)于粘滯流體,流速可選擇大于2m/s,較大的流速有助于自動(dòng)消除電極上附著的粘滯物的作用,有利于提高測(cè)量精度。
在量程Q已確定的條件下,即可根據(jù)上述流速V的范圍決定流量計(jì)口徑D的大小,其值由下式計(jì)算:
Q=πD2V/4
Q:流量(㎡/h) D:管道內(nèi)徑 V:流速(m/h)
電磁流量計(jì)的量程Q應(yīng)大于預(yù)計(jì)的*大流量值,而正常的流量值以稍大于流量計(jì)滿量程刻度的50%為宜。
*大流量和*小流量必須符合下表中的數(shù)
