Davis Instruments 6415

The Davis Instruments 6415 Sonic Anemometer measures wind speed and wind direction without any moving parts. This adds even more ruggedness and reliability with minimal maintenance. The Davis 6415 has pairs of electro-acoustic transducers in the anemometer which send pulses back and forth. Time is measured for how long it takes the pulse to travel from one to the other. Movement of air affects the pulse travel time. This allows the anemometer to calculate wind speed and direction which is calibrated by temperature measurements. The Davis Sonic Anemometer 6415 features a solar panel that charges its own factory-installed battery, no external power needed.

The sonic anemometer can be used to upgrade your existing Vantage Pro2 weather station and Vantage Pro2 ISS. When used with a Sensor Transmitter 6331 or 6332, it can be used to include additional wind stations in your existing system when reporting to a WeatherLink LIVE hub. Includes mounting hardware, battery, alignment tool and 40' cable.
