This rugged anemometer with dual digital display handles speeds from 5 km/h to over 200 km/h. Comes with 8m of audio grade wire, with a 2.5mm jack connection to the display (unlike the Pole Mount anemometer which comes with exterior grade wire and no connector). The Vortex FlexWire anemometer is great for mobile use where AC power is not available. Pole not included.
You can mount this anemometer to your own pole or roof bracket, bring the wire in through a window or some other hole, and stick the display on the glass, a window, or anywhere you want. Connect the display and Voila!
The Vortex FlexWire anemometer is an accurate, affordable way to provide you with wind speed in places where AC power may not be available.
The Vortex FlexWire portable anemometer includes a high quality, Cateye Velo8 brand bicycle computer to display wind speed. It also captures and stores MAX and AVERAGE wind speed, and includes wind mile odometers and a clock (basically stuff that cyclists care about but also apply to wind). Speed range is approx. 5 to around 250 km/h. Calibration has only been verified from 5 to 80 - we did not find a wind tunnel with 250 km/h calibration facilities! Check out the specification tab or
here for details. Battery life is around 1,000 hours of continuous use.

Since bicyclists do not want their average speed to be diminished when they come to a stop, the computer will only record and average when the wind is blowing. It stops recording below approximately 1 mph. That means that if the wind blows for 2 hours at 20 mph and 2 hours at zero, the average shown will be 20, not 10! Please keep this in mind for your desired use of the Vortex.
WORKAROUND: If you want to know the real average wind speed - even with spells near zero, do the following: reset the computer, note the time. When desired, simply divide the total number of wind "miles" on the display by the number of hours since reset.
