电磁流量计(EMF)是测量导电液体体积流量的最佳仪器选择。约80%的场合可以采用脉冲直流场励磁(磁场线圈励磁类型)技术,如水的连续流量计量。然而,由于流体的物理或水力特性,在一些场合中需要采用具有交流磁场励磁的EMF,如固含量高或电导率非常低的流体(见图1)。图1脱墨过程中的 Electromagnetic flowmeters (EMFs) are the best instrument to measure the volume flow of conductive liquids. About 80% of occasions can be pulsed DC field excitation (field coil excitation type) technology, such as continuous water flow measurement. However, due to the physical or hydraulic properties of fluids, EMF with AC field excitation, such as fluids with high solids or very low conductivity, is required in some applications (see Figure 1).
