Sampling method is the basic method used in evaporation from water surface. Based on present situation of sampling method, we designed a new technology on measurement evaporation of water surface in short time-scale and made it true. The work principle of the technology was dynamic water balance. Based on self-recording water measurement technique of tilting bucket, the new technology took the place of traditional way which relied on water-level fluctuation in a pan. Using the self-designed device, the short-time-scale measurement of free water surface evaporation realized in constant water depth. In addition, the process of water evaporation could be self-measured. The new technology improves measurement precision and enriches means of free water surface evaporation in short time.
