Sonic AnemometerMeasure wind with no moving parts. Use with a Sensor Transmitter or an EnviroMonitor Node, or as a replacement anemometer for wireless and cabled Vantage Pro2.The D avis Sonic Anemometer has no moving parts � it measures wind speed and direction with electro-acoustic transducers that send sonic pulses back and forth. The time it takes for the pulses to travel from one transducer to the other is affected by the movement of air. Speed and direction can then be calculated, with calibration for air temperature. The Sonic Anemometer has its own solar panel that charges an internal battery. It can be used with an EnviroMonitor Node, or as a replacement anemometer for your Davis weather station. It can also be installed in a Sensor Transmitter to create additional wind stations when reporting to WeatherLink Live.Solar-powered with battery backup.
