摘要：
Magnetic field induced by different shapes of excitation coil was simulated from the angle of the weighting function, three indicators, the magnetic flux density along the central axis of the distribution of evenness, along the measuring tube axis of the distribution uniformity and the uniformity of the distribution in the whole space were defined to analyse their magnetic field uniformity respectively, and then the optimal coil shape was chosen. And in the situation of the same coil material cost and the same excitation condition, the relationship between EMF induced by different shape coils and the measured liquid velocity and the level of liquid in the pipe was simulated. The results show that the circular coil magnetic field uniformity is the best. The selection of the best shape of the exciting coil has been done based on the measured liquid level in the pipe line in practical application. © 2016, Central South University Press.
