Abstract: A liquid delivery system includes a source of hydraulic fluid and a hydraulic cylinder fluidically coupled to the source of hydraulic fluid and having a hydraulic piston movable between first and second limit positions. The liquid deliver system includes a rod connected to the piston and extending out of the hydraulic cylinder and a sensor device located outside the hydraulic cylinder and configured to sense a position of the rod and to generate a signal indicating the sensed position. The liquid delivery system includes a liquid cylinder comprising a liquid piston, operably driven by the rod, to pump a liquid along a flow path to a fluid applicator.

Abstract: A fluid spraying system includes a fluid applicator having a tip that atomizes a fluid. The fluid spraying system also includes a pump configure to pump the fluid from a fluid source to the tip and a control system. The control system identifies at least one characteristic of the tip or the fluid and communicatively couples to the pump. The control system also controls an operating characteristic of the fluid spraying system based on a characteristic of the tip or the fluid.
