产品简介
分体式电磁流量计是一种根据法拉第电磁感应定律来测量管内导电介质体积流量的感应式仪表,采用单片机嵌入式技术,实现数字励磁,同时在电磁流量计上采用CAN现场总线,属国内首创,技术达到国内领先水平。
分体式电磁流量计在满足现场显示的同时,还可以输出4~20mA电流信号供记录、调节和控制用,现已广泛地应用于化工、环保、冶金、医药、造纸、给排水等工业技术和管理部门。
电磁流量计除可测量一般导电液体的流量外,还可测量液固两相流,高粘度液流及盐类、强酸、强碱液体的体积流量。
性能特点
仪表结构简单、可靠,无可动部件,工作寿命长。
无截流阻流部件,不存在压力损失和流体堵塞现象。
无机械惯性,响应快速,稳定性好,可应用于自动检测、调节和程控系统。
测量精度不受被测介质的种类及其温度、粘度、密度、压力等物理量参数的影响。
采用聚四氟乙烯或橡胶材质衬里和Hc、Hb、316L、Ti等电极材料的不同组合可适应不同介质的需要。
备有管道式、插入式等多种流量计型号。
采用EEPROM存贮器,测量运算数据存贮保护安全可靠。
具备一体化和分离型两种型式。
高清晰度LCD背光显示。

量程范围确认
一般工业用电磁流量计被测介质流速以2~4m/s为宜,在特殊情况下,最低流速应不小于0.2m/s,最高应不大于8m/s。若介质中含有固体颗粒,常用流速应小于3m/s,防止衬里和电极的过分磨擦;对于粘滞流体,流速可选择大于2m/s,较大的流速有助于自动消除电极上附着的粘滞物的作用,有利于提高测量精度。
在量程Q已确定的条件下,即可根据上述流速V的范围决定流量计口径D的大小,其值由下式计算:
Q=πD2V/4
Q:流量(㎡/h) D:管道内径 V:流速(m/h)
电磁流量计的量程Q应大于预计的最大流量值,而正常的流量值以稍大于流量计满量程刻度的50%为宜。
最大流量和最小流量必须符合下表中的数
