Abstract (en)
[origin: WO2017222666A1] A liquid delivery system (900) is presented. The liquid delivery system (900) comprises a source of fluid coupled to an outlet. The liquid delivery system also includes a hydraulic cylinder (912) coupled to the source of fluid. The hydraulic cylinder has a piston (914) movable between a first limit position and a second limit position during an operational cycle. The hydraulic cylinder (912) is configured to pressurize fluid received from the source of fluid, and deliver the pressurized fluid to the outlet. The liquid delivery system (900) also comprises a rod connected to the piston and extending out of the cylinder. The liquid delivery system (900) also comprises a sensor (916) configured to sense a position of the rod to provide a signal indication of the piston (914) with respect to the first position or the second position. An indication of the sensed position is provided to a controller (920), and the controller (920) is configured to send a control signal to initiate a normal operation loop based on the sensed position.
