The wind speed measurements part of the Wind cup anemometer use computer technology. It can measure five parameters: They are the instantaneous wind speed, instantaneous wind scale, the average wind speed, the average wind level, and corresponding wave height. It has taken many measures to reduce power consumption, greatly reducing the power cost of the device. Which function with a data latch for easy reading. In the wind direction detective part, it uses the auto referring to north device, without manual operation to define the north. Greatly simplify measurement operation. The merits of the instrument include small size, light weight, full-featured, low power consumption etc. So it can be widely used in field like agriculture, forestry, oceans, used for scientific exploration, meteorology or teaching which need the measurement of the atmospheric wind parameters.
