電(dian)磁流(liu)(liu)量計是市面上(shang)使用多的流(liu)(liu)量計，廣(guang)泛應用在石化，農業等(deng)方面，能實現對導電(dian)液體的流(liu)(liu)量測量。

日常使用中，很多人對于選(xuan)型(xing)存在一定的問題，下面簡單介紹下，電磁流(liu)量計如何選(xuan)型(xing)。

首先，我們需(xu)要(yao)確(que)認管(guan)道大(da)小，介質(zhi)(zhi)和(he)流量范(fan)(fan)圍，這兩(liang)點是(shi)(shi)選(xuan)型基本的(de)要(yao)求(qiu)(qiu)，也直接影(ying)響著報價。管(guan)道大(da)小和(he)流量范(fan)(fan)圍的(de)影(ying)響不用(yong)(yong)(yong)(yong)說，介質(zhi)(zhi)決定(ding)襯(chen)里跟電(dian)(dian)(dian)極(ji)。水這類(lei)無腐蝕性的(de)介質(zhi)(zhi)，可以選(xuan)用(yong)(yong)(yong)(yong)橡(xiang)膠襯(chen)里，316L電(dian)(dian)(dian)極(ji)。鹽酸這類(lei)腐蝕性介質(zhi)(zhi)選(xuan)用(yong)(yong)(yong)(yong)4F襯(chen)里，鉭電(dian)(dian)(dian)極(ji)（強酸）或(huo)者鈦(tai)電(dian)(dian)(dian)極(ji)（強堿）。緊接著是(shi)(shi)溫(wen)(wen)(wen)度(du)(du)和(he)壓(ya)力的(de)確(que)認。注(zhu)意(yi)，我們需(xu)要(yao)確(que)認的(de)是(shi)(shi)工(gong)作壓(ya)力和(he)工(gong)作溫(wen)(wen)(wen)度(du)(du)，工(gong)作壓(ya)力決定(ding)著額(e)定(ding)壓(ya)力等級的(de)大(da)小，工(gong)作溫(wen)(wen)(wen)度(du)(du)超過100℃就得(de)選(xuan)用(yong)(yong)(yong)(yong)4F襯(chen)里。后，根據現(xian)場使用(yong)(yong)(yong)(yong)的(de)要(yao)求(qiu)(qiu)，選(xuan)擇供電(dian)(dian)(dian)方式和(he)通訊要(yao)求(qiu)(qiu)。例如在戶外(wai)使用(yong)(yong)(yong)(yong)的(de)選(xuan)用(yong)(yong)(yong)(yong)鋰(li)電(dian)(dian)(dian)池供電(dian)(dian)(dian)，想在戶外(wai)使用(yong)(yong)(yong)(yong)并且在室內接受數據就得(de)用(yong)(yong)(yong)(yong)鋰(li)電(dian)(dian)(dian)池供電(dian)(dian)(dian)帶GPRS功能。我們一般使用(yong)(yong)(yong)(yong)的(de)電(dian)(dian)(dian)磁(ci)流量計(ji)都(dou)是(shi)(shi)220V或(huo)者24V供電(dian)(dian)(dian)的(de)，現(xian)在的(de)表頭都(dou)是(shi)(shi)標配(pei)4-20mA和(he)RS485通訊的(de)。
