Abstract
A method for pumping, tracking, and controlling a fluid includes the steps of producing a drive signal for driving a motor of a pump using a controller, driving the motor to pump a fluid based on the drive signal, sending a dispense signal from the controller to a sprayer for dispensing the fluid, determining a work piece count as a function of a work piece signal provided to the controller from the work piece sensor, detecting the position of a rod connected to the motor and the pump using a position sensor, creating a position signal as a function of the position of the rod using the position sensor, sending the position signal to the controller, and determining a volume usage as a function of the position of the rod using the controller.
