This version of the WindSonic 2-D Sonic Wind Sensor has a military style connector instead of pigtails that connects to the RAWS-F Fire Weather Quick Deployment Station. The WindSonic, manufactured by Gill Instruments Ltd., is a two dimensional ultrasonic anemometer for measuring wind speed and direction. The WindSonic is an alternative to traditional mechanical cup and vane or propeller and vane anemometers. The WindSonic does not have moving parts, which minimizes routine maintenance.
