摘要
超声波流量计是一种非接触式测量的流量测量设备。文章主要从超声波时差法测量原理出发,设计一种以高精度时间间隔测量芯片TDC-GP21为计时核心,低功耗单片机MSP430单片机为控制核心的硬件系统,可以实现高精度、低功耗的流量测量要求。
The ultrasonic flowmeter is a non-contact measurement equipment.Based on the measurement principle of the ultrasonic time-difference method in this article,a kind ofhardware system is designed by using a high-precision time interval measuring chip TDC-GP21 as the core of timing and a low power consumption MCU of MSP430 as the core of conducting in thesystem,canachive the requirements of flowmeter measure of high-precison and low power consumption.
