低功耗涡街流量计的硬件设计

摘要

低功耗涡街流量计适用于电池供电并具有温度补偿的单相流体测量功能,是适合于脉冲、频率传感器输出的两线制、低功耗二次流量测量显示的标准工业仪表.该流量计采用超低功耗TI公司的MSP430F449系列单片机设计,具有电池充电、液晶显示、多输出方式和掉电数据保护存储等功能.%Lowpower vortex flowmeter is applied to battery power with a temperature compensationof single - phase fluid measurement. It is a low power consumption and standard industrial instrument which is suitable for the pulse or frequency of the two - wire sensor output, measurement and display of the second flowrate. The flowrate meter is designed by using TI＇ sultra - low power MSP430F449 MCU. It has a battery charger, liquid crystal display, multi -output mode and power- down data protection storage features.
