Inspeed's FlexWire 3-Cup Anemometer

Inspeed's rugged and affordable FlexWire Anemometer combines a high quality, Inspeed-designed, Made In America wind speed sensor with a bicycle speedometer to accurately monitor wind speeds up to 125 mph (sadly the 200 mph option is no longer available from Sigma Sport).

Mount the wind speed sensor to your own pole or roof bracket, route the 25' wire however you wish and stick the display on the glass, a window, or anywhere you want. Then, connect the display and voila-you’re ready to measure wind speed!  Great for folks who want to know how fast the wind is blowing without spending $350, and for sites where AC power may not be available.

The display is a bicycle speedometer - one of two models:  the Cateye Velo7, limited to a maximum speed of 125mph.  We use bicycle speedometers because they give you the biggest bang for the buck:  low cost, fast update rates, dual display of current speed along with your choice of max or average.

The wind speed sensor comes standard with a vertical metal mounting bracket and a 25' mono audio cable that we adapt for this product - which includes a 1/8" jack connection to the display.  Options for shorter lengths are available as an option. If you need something special, don't hesitate to reach out to us - we will see what we can do!
