How can I obtain a pwm in order to measure frequency of PWM?

I want to use magnetometer to calculate the RPM of an impeller.

Question relating to:

Background calibration for magnetometers, both gain and offset errors are removed (hard/soft iron). Calibrate, compass, Magneto

So what is the question?
