Abstract: A device for monitoring evaporation capacity of a water surface evaporator in a process includes a water surface evaporator and a rain collector, the rain collector and the water surface evaporator having a same size of orifice area, height, and contour profile of a monitoring device. One side of the water surface evaporator is connected with a first measuring well through a pipeline, and another side of the water surface evaporator is connected with a first electromagnetic flowmeter, a water supplementing electromagnetic valve and an overflow electromagnetic valve through a water pipe. The water supplementing electromagnetic valve is connected with a water supplementing barrel through a water supplementing pipe. A water collecting barrel is installed below the special rain collector. A second magnetostrictive water level meter, a starting drainage switch and a stopping drainage switch are installed in the second measuring well.
