本ientek的磁性电子流量计(EMF)利用了法拉第导电原理，法拉第曾试图利用磁体来测定泰晤士河水的流速，公司正是受此启发而设计了本流量计。
ientek的EMF系列产品利用了公司长期积累的技术经验，并引入了高新技术，在流量测量领域并广泛使用，以其优秀的性能广受好评。适合用于口径在6mm到1000mm范围内的配管，并且只要流体导电率在1
u S/cm以上，流量的测定就不受测定体的密度、传导性、温度、压力、固体物的有无的影响。
流量计的内部涂层采用了特氟龙(PTFE)、工学塑料、轻型橡胶、不锈钢 (STS316) 等材料，电极采用了不锈钢 STS316、镍基合金"c"
、坦类等材料。
精密度以±0.5%为基准，根据顾客的需求，还可生产±0.02%精密度级的产品。
