Manual meter reading was main way in traditional water management. It was not only waste of human and material resources, but also very inconvenient. Especially in recent years, with the emergence of a number of high residential, this way of water management was obviously inefficient. In this paper, based on the study of existed water meters, a kind of design schema of intelligent water meter was introduced, which was based on PIC16F946 microcontroller. By this way, the efficiency of water management can be improved.
