摘　　要：本系统采用了光电折射原理来实现贮水水箱液位检测,传感器由发射二极管和光敏三极管组成的光断续器.检测部分与待测液体介质完全不接触,能够清晰稳定的显示实际水位,在水位超出上、下限时能发出声光告警信号.This system uses the principle of photoelectric refraction to achieve the liquid level detection of water storage tank, with the optical chopper sensor composed of launch diodes and phototransistor. Since the detection unit has no direct contact with the liquid,the water level can display clearly and stable and Acousto-optic alarm can be issued when the water level is beyond the upper and lower limit.
