Product Details
Sonic™ Anemometer by Davis Instruments®. Measures wind velocity and direction in one compact unit. The Sonic Anemometer has no moving parts – it measures wind speed and direction sonically. 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.

Pairs of electro-acoustic transducers send sonic pulses back and forth. The time it takes for the pulse 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.
