Abstract A fluidic electronic water meter based on the permanent magnet excitation electromagnetism examination method is described. Its structure principle,the major technique characteristic,the flow measurement characteristic,as well as the sensing and the signal processing technology are studied.In view of the fluidic electronic water meter is for small flow measurement the improvement idea and the method in the theoretical analysis and the experiment foundation is proposed.After volume production of the fluidic electronic water meter, it proves that the small flow characteristic idea and the method are effective.
