摘要
新型流速传感器采用红外调制电路以克服环境光对流速测量的影响 ,流速数据采集系统采用工业化脉冲计数模块 .因此 ,该系统具有较好的稳定性和可靠性 ,且成本低 ,配置方便 .
The new type velocity sensor takes infrared modulation circuit to lower the effects of surrounding light on velocity measurement, and its the velocity data acquisition system is equipped with industrial pulse counting block. Thus, the system is more stable and reliable than the previous one, and its price is lower.
