| Abstract: | 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. |
