Weeder Technologies Velocity Measurement cards with free Window's software

Measuring the speed of a projectile can be accomplished by having it cross over two physical points separated by a known distance and using the points to start and stop a timer. Our small low-cost counter/timer card which hooks up to the RS-232 or USB port of a computer has two trip wire inputs which can serve as a start and stop trigger for its internal timer. When the projectile breaks the first trip wire the timer starts and when it breaks the second trip wire the timer stops. The accumulated time which will be shown on the computer screen can then be used to calculate the speed of the object.
