摘　　要：本文介绍一种以激光作为测量光源， 利用光敏电阻随光线强弱变化而阻值随之变化的特性， 控制或门电路工作，This paper introduces a photoelectric water level measurer in which laser is used as the light source and the on-and-off circuit is controlled by a photoelectric resistance which changes with the light intensity. The water level can be represented by the adjustable output of the voltage generator and is shown on the digital voltmeter.
