  Bicycle Speedometer Anemometer
It uses a digital bicycle speedometer to count pulses from a magnet and reed switch on the anemometer cup assembly, and the speedometer translates this automatically to mph or kph.
The sensor wire with the speedometer is only a couple feet long, so we snipped it and used telephone wire to extend it to 20 feet long, so it could run right into the house for mounting the speedometer disply inside.
The bike speedometer uses the measured circumference of a bicycle tire to calculate the bike's speed, using the number of tire revoluitions per minute as tallied by the sensor mounted ot the bike and the magnet mounted to the wheel.

 Vehicle Speedometer Questions
We hit a patch of ice as we were accelerating to avoid a motorist who lost control and all wheels slipped and spun causing the speedometer to "bounce." After all the excitement the gauges were "bouncing" and we noticed the odometer had approximately 20,000 more miles on it than it had.
They also replaced the speedometer cable (after reaching 40 mph it was swinging back and forth between 40-65 mph making it difficult to get an accurate speed).
Answer: The speedometer problem may be caused by the speedometer cable binding or the speedometer head itself.

 BMW Speedometer Accuracy
When the motorcycle is moving the speedometer cable rotates the magnet, which causes a twisting force on the speed cup.
The speedometer is adjusted by changing the relationship between the angular velocity of the magnet and the position of the speed cup/pointer.
This is done by taking the speedometer off the bike and using a variable speed drill to simulate the rotation of the speedometer cable as shown in Figure 2.

 Stanley Speedometer & Odometer Restoration
The speedometer swivel drive and cable had been removed long ago and was part of a box of parts the came with the car.
Along with the speedometer was sent the outside diameter measurement of the car’s tires and the diameter and number of teeth on the speedometer drive gear mounted to the front right wheel hub.
As the proper calibration of the speedometer relied on the proper fiber gear being installed on the swivel drive, several gears were supplied for the reinstallation and future use (the fiber gears wear and should the drive lock up a shear pin breaks to release the fiber gear from the swivel drive).

 Speedometer Installation Tips
A bicycle speedometer is most useful, not as a speedometer ("I know I was doing at least 25 when I hit the tree, because I was trying to read my speedometer at the time..."), but as an odometer.

Typically, they are driven by either the vehicle's wheel-speed sensors or, more commonly, by a "variable reluctance magnetic sensor" reading the speed of the passing teeth on a gear in the transmission.
All our speed measurements were made on cars with new stock tires correctly inflated, but one might expect a manufacturer to account for wear and to bias the speed a bit low; results suggest that not to be the case.
So the four-percent allowable range on an 85-mph speedometer is 3.4 mph, and the acceptable range on a 150-mph speedometer is 6.0 mph.
