Abstract
Methods and apparatus for calibrating controllers for use with wells are disclosed. An example method includes moving a polished rod of a pumping unit through a first cycle of the pumping unit using a motor and determining first pulse count values of the motor through the first cycle using a first sensor at first times. The first times are substantially equally spaced. The method also includes determining first position values of the polished rod through the first cycle using a second sensor at the first times and associating the first pulse count values with respective ones of the first position values to calibrate a processor of the pumping unit.
