Abstract :
In this paper, we present a design of new type of water meter with nonmagnetic and low power. Some kinds of flow measurements are analyzed, and we discuss the principle of the nonmagnetic sensor used by LC oscillating circuit measuring water flux in detail. The MSP430FW427 is used as MCU with the function realized by the SCAN IF module without IC circuit external, which improves the precision and sensitivity of flow measurement. It realizes the fluid flow measurement and in this paper the correlative design of hardware and software are introduced.
