測量強酸強堿|泥漿膠水特殊液體電磁流量計—DLK3611

產品概述

       DLK3611電磁流量(liang)(liang)(liang)計(ji)（熱(re)量(liang)(liang)(liang)表）由傳感器(qi)和(he)轉換器(qi)兩(liang)部分構成。可(ke)以(yi)除測(ce)(ce)量(liang)(liang)(liang)一般導電介質外，還可(ke)測(ce)(ce)量(liang)(liang)(liang)強酸(suan)強堿，泥漿膠水(shui)等(deng)特(te)殊液體。廣泛用(yong)于石油(you)化工(gong)、造紙、環保、食品及市政水(shui)利檢測(ce)(ce)等(deng)領域(yu)。

工作原理

       根(gen)據法拉第電(dian)(dian)(dian)(dian)(dian)磁(ci)感(gan)(gan)應原理，在與(yu)測(ce)(ce)量(liang)管軸線(xian)和磁(ci)力線(xian)相垂直(zhi)的管壁上安(an)裝(zhuang)了一對檢(jian)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)極(ji)，當導電(dian)(dian)(dian)(dian)(dian)液(ye)體(ti)沿測(ce)(ce)量(liang)管軸線(xian)運動時，導電(dian)(dian)(dian)(dian)(dian)液(ye)體(ti)切割磁(ci)力線(xian)產生感(gan)(gan)應電(dian)(dian)(dian)(dian)(dian)勢(shi)，此感(gan)(gan)應電(dian)(dian)(dian)(dian)(dian)勢(shi)有兩個檢(jian)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)極(ji)檢(jian)出，數值大小與(yu)流(liu)量(liang)正比例，其值為：E=B*V*D*K；E=感(gan)(gan)應電(dian)(dian)(dian)(dian)(dian)勢(shi)；K=與(yu)磁(ci)場分(fen)布及軸向長度(du)有關的系數；B=磁(ci)感(gan)(gan)應強(qiang)度(du)；V=導電(dian)(dian)(dian)(dian)(dian)液(ye)體(ti)平均流(liu)速；D=電(dian)(dian)(dian)(dian)(dian)極(ji)間距；（測(ce)(ce)量(liang)管內直(zhi)徑）。

       傳感器將感應電勢E作為流量信號(hao)，傳送(song)到轉換器，經放大，變(bian)換濾波等一系列的(de)數字(zi)處理后(hou)，用帶(dai)背光的(de)點陣式液晶顯示瞬時流量和累積流量。轉換器有4~20mA輸出，報(bao)警輸出及頻率輸出，并設(she)有RS-485等通訊接口，支持HART和MODBUS協議。
