摘　　要：鉴于超声波传感器在管道上的安装问题,设计了直通式管道,彻底解决了超声波传感器的入射角问题,采用高精度的时间测量芯片TDC-GP2解决了时差法的测量精度问题,并采用了当前最流行的低功耗单片机MSP430作为积算仪,通过软件设置,使系统能以较低的功耗工作。According to the existing problem of the ultrasonic sensors installed on the pipe, this paper designs a straight-through pipe, which is used to solve the incident angle of ultrasonic sensors and uses a high-precision time measurement chip TDC-GP2 to solve the transit-time measurement accuracy, and takes the most popular low-power microcontrollers MSP430 as totalizer which can be applied to lowering power consumption in the operation by settings software value.
