摘　　要：介绍了数字光纤流量计的设计思路与制作过程 :利用浮子带动转轮 (光闸 ) ,实现光纤信号的编码 ,进而由单片机进行信号处理 ,完成判向与流量的计算 .然后串行输出到数码管 ,显示当前流量值 .结合测试结果分析了此系统的优点与不足之处 ,并就系统的进一步完善与实用化提出了几点建议 .A rotating wheel (light gate) driven by floater is used to achieve digital encoding. The SCM receives the digital signal and distinguishes the direction and calculates the flowrate. The result is displayed on LED. Advantage and disadvantage of the system were discussed based on the consequence. Furthermore, the improvement methods for practical utilization were pointed out.
