Wind Speed & Direction:
  • Wind Speed Only = Sensor measures wind speed only
  • Wind Speed & Direction = Sensor measures wind speed and direction wind is blowing from.
  • Standard = Standard range sensor (Up to Approx. 250 metre Line of Sight)
  • Extended = Extended range sensor (Up to Approx. 1000 metre Line of Sight) [Includes FREE remote antenna with Magnetic base]


The WL12 is a long range wireless anemometer and data logger. The WL12 anemometer can measure wind speed only or wind speed and direction, depending on the sensor you select. The display unit connects to the anemometer via its own 868 MHZ radio and can transmit up to 1000m (line of sight). The WL12 also logs all readings on an SD card in the display unit. This data can then be analysed post event for time stamped wind ratings. You can view current, average & maximum wind speed, wind direction and temperature from the display unit.
