Product Details

    • Introduction:
      This WB-2 anemometer is a fully digital, high-precision instrument for measuring wind speed and wind direction, based on ultrasonic principles. It features automatic heating to prevent ice and snow accumulation and boasts all-digital operation. Thanks to its ability to effectively overcome the inherent drawbacks of mechanical anemometers, it can operate reliably and continuously under all weather conditions, making it increasingly popular and positioning itself as a powerful replacement for traditional mechanical anemometers.


      Features:
      Compared to traditional mechanical anemometers, which tend to wear out quickly and require cumbersome maintenance, ultrasonic anemometers have the following advantages:
      No cut-in wind speed limit, fast response time, and capable of measuring both wind speed and wind direction.
      No moving parts, minimal wear, low maintenance, long service life, and no maintenance or on-site calibration required.
      Wide measurement range, capable of operating around the clock, unaffected by heavy rain, snow, ice, or frost.
      High measurement accuracy and stable performance; robust structure with excellent corrosion resistance.


      Interface:
      Communication Protocol: Complies with NMEA0183-WIMWV
      The NMEA output format is: $WIMWV,ddd,R,www.ww,N,A*cc. Refresh rate: once per second.


      Installation and fixing:
      When installing, ensure that the instrument is placed horizontally and that the “N” directional marker at the bottom of the cylinder wall points precisely toward true north. The instrument is secured and locked in place using four M6 screws, as shown in Figure 3.1.
