Abstract
Embodiments disclosed herein propose a precision spray pumping system including a positive displacement pump in fluid communication with at least one spray nozzle. The positive displacement pump includes a displaceable member, and displacement of the displaceable member corresponds to a pumping cycle of the positive displacement pump. A controller is in communication with the positive displacement pump. The controller is operable to apply an actuation parameter to direct a displacement of the displaceable member and is also operable to receive an indication of an actual position of the displaceable member. The controller is further operable to compare a predetermined actuation parameter associated with an expected displacement of the displaceable member to a measured actuation parameter associated with the actual position of the displaceable member.
