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 (200 mph as an option).

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 and an optional Sigma Sport MC10 that is good to 200 mph.  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.  If you need something special, don't hesitate to reach out to us - we will see what we can do!
