WSR/WDV-Wind Speed and Direction Sensor

Wind Speed & Direction Sensor

The RainWise multivane wind speed and wind direction sensor consists of a multi-vane rotor and wind direction vane mounted on a anodized aluminum support tube.

RainWise modeled the multi-vane rotor after a similar design that was used to measure the wind speed of 231 miles per hour on top of Mount Washington. Since it was introduced, some eighteen
years ago, we have sold over 15,000 of them. It is the most rugged and reliable mechanical method of measuring wind speed and direction that we know of. The RainWise multi-vane anemometer has been wind tunnel tested at the Stennis Space Center at speeds of 140 MPH. The accuracy is traceable to NIST.

The WSR operates with an optical switch. The
pulses generated each revolution are counted over a known period of time and this output is the wind speed. Heaters are an available option for the WSR.
For battery/solar powered systems the WSR is also available with a dry reed switch output.

The WDV consists of two magnets positioned on the vane at an angle of 140 degrees. These magnets actuate 9 dry reed switches mounted below them, producing 36 discreet nine-bit binary outputs. This information is placed into a shift register and sent down the connecting cable in a serial string. The direction sensor is programmed to indicate “630” if there is any malfunction in the system.

Both the WSR and the WDV are available separately. A heated version of the WSR is also available.
