The working principle of wind speed and direction finder: part 1, the wind: by the vane, the wind dial ( Magnetic compass) And so on, the wind by wind pointer value for the location of the wind on the dial. Part 2, wind speed: the traditional three-ring rotating frame structure, the instrument inside the single chip microcomputer sampling, for the wind speed sensor's output frequency is calculated, after zui instrument output instantaneous wind speed, average wind speed, the instantaneous wind scale, one minute one minute average wind scale, average wind speed and wave height. Measured parameters on the liquid crystal display with digital display directly.

wind speed and direction finder main technical indicators: 1, the wind speed technical indicators measuring range 0 0 ~ 30 m/s start wind speed. 8 m/s measuring accuracy, 0. 3 + 0. 03. (五) m/s（ V indicates wind speed) Instantaneous wind speed, the average wind speed, the instantaneous wind scale wind speed parameter, average wind scale, and the corresponding waves of display resolution 0. 1m/s（ Wind speed) Level 1 ( Wind scale) 0. 1米( Waves of) 2, the technical indicators measuring range 0 ~ 360 degrees, 16 bearing start wind speed. 0 m/s 1/2 azimuth direction measurement precision north auto - 3, working environment temperature 10 ~ 45度; C humidity ≦ 100% RH ( No condensation) 4, 3 v power supply ( 3. 4 to 2. 68V) 2 no. 5 batteries 5 size, size and weight 410 x100x100mm3 weight 0. 5公斤
