电磁流量计是由传感器和转换器两部分构成，基于法拉第电磁感应定率进行工作，用来测量导电性的液体或两相介质，要求其电导率一般应大于5US/cm（自来水原本的电导率约 100-500US/cm），可以用来测量各种酸、碱、盐溶液、纸浆、矿浆等介质，但介质中不 能含有较多的铁磁性物质和大量气泡。产品适用范围：2、接触被测介质的只有衬里和电极，只要合理选用衬里和电极材料，就可达到良好的耐腐蚀性和耐磨性，因此，可测量各种强酸、强碱等化工溶液。测量流量时，流体流过垂直于流动方向的磁场，导电性液体的流动感应出一个与平均流速成正比的电势，因此要求被测的流动液体高于最低限度的电导率。其感应电压信号通过两个电极检出。并通过电缆传送至转换器，经过信号处理及相关运算后，将累计流量和瞬时流量显示在转换器的显示屏上。天津WP-EMF-A(40)1A1AC10T52D全国天津WP-EMF-A(40)1A1AC10T52D全国天津WP-EMF-A(40)1A1AC10T52D全国
电磁流量计是一种主要的流量仪表，广泛地应用于石油、化工、冶金、轻纺、造纸、环保、食品等工业部门及市政管理，水利建设等领域的流量测量。 
工作原理：
电磁流量计传感器的测量系统是基于法拉第电磁感应定率，在与测量管轴线和磁场磁力线 相互垂直的管壁上安装一对检测电极，当导电液体沿测量管轴线运动时，导电液体作切割磁力线运动产生感应电势。此感应电势由测量管上的两个电极检出，数值大小为：
E=KBVD
其中：E感应电势；K仪表常数；B磁感应强度；V测量管截面内的平均流速；D测量管的内直径。
测量流量时，流体流过垂直于流动方向的磁场，导电性液体的流动感应出一个与平均流速成正比的电势，因此要求被测的流动液体高于最低限度的电导率。其感应电压信号通过两个电极检出。并通过电缆传送至转换器，经过信号处理及相关运算后，将累计流量和瞬时流量显示在转换器的显示屏上。
仪表特点：
1、测量管内无阻流及活动部件，因此不会造成额外的能量损失，也不会造成堵塞，因此节能效果显著，特别适宜液固两相流如污水、泥浆、矿浆、水煤浆、纸浆等的测量。
2、接触被测介质的只有衬里和电极，只要合理选用衬里和电极材料，就可达到良好的耐腐蚀性和耐磨性，因此，可测量各种强酸、强碱等化工溶液。
3、安装要求低。前直管段只要5D，后直管段为2D（D为所选仪表的内直径）。
4、测量精确度不受流体密度、粘度、温度、压力和电导率变化的影响，而且可测量正/反两个方向的流量，这就为精确测量流量提供了很好的手段。
5、仪表功耗小。小于5VA。
6、转换器具有良好的互换性，不必重新进行实流标定就可达到精度。由于电磁流量计有一系列优点，因此在各行业得到越来越广泛的应用，成为液体 流量测量的首选仪表。
