| Abstract: | In this paper,the working principles of IC card watermeter are introduced,the errors in the IC card electronic watermeter system are analyzed,and the linearization correction technique using software method is brought forward.Then a set of new equipment based on traditional demarcating equipment is devised,the feedback circuits of linear interpolation are applied to calculate the correction coefficients of revolution number,so as to demarcate the watermeter automatically. |
