Report on the development of an electronic evaporimeter

This text introduces a pocket electronic instrument which is designed by the method of Ultrasonic pulses and is able to digitally display the meaned results of the evaporation and the water level. The working principles of the instrument, the calculation, the measuring circuit and the experimental results have been discussed and analyzed. The status of the evaporating observation and the problems about its automation have been discussed as well.
