摘　　要：该系统是以MSP430F247单片机为核心。涡街流量计传感器输出信号经放大滤波后输入比较电路,得到脉冲信号,单片机对此脉冲信号进行测频,得到相应流体的瞬时流量,并将其显示。该系统功耗低,可以直接由两节干电池供电运行,还有节电和自检功能。The system is based on MSP430F247 MCU as the core. The vortex flow sensor output signal, being amplified, filters and then inputs into the comparator to get a pulse signal. The MCU measures the frequency of the pulse, figureing out the corresponding instantaneous flow of fluid, and then displays. The power consumption of flowmeter is low because of being driven by two dry batteries and having function of power saving and self-checking.
