Water surface evaporation sensor can accurately measure unit area of water surface evaporation, using high precision weight principle to measure the weight of liquid in the evaporation dish, then calculate the liquid level height. Therefore, it can be used in a variety of environments, such as liquid or frozen, which solves the problem of using ultrasonic principle to measure liquid level height (1, when frozen, the measurement is inaccurate, 2, it is easy to damage the sensor when there is no water, 3, the accuracy is low), and can be used with automatic meteorological station or professional evaporation recorder.
