Abstract
First piston position data of a piston in a displacement unit is obtained based on an output signal from a sensor associated with the displacement unit, the output signal being dependent upon a physical position of the piston in the displacement unit. Second piston position data of the piston in the displacement unit is obtained based on data indicative of a number of revolutions of a hydraulic motor in a hydraulic system, the hydraulic system being operable to drive the piston of the displacement unit. Based on the second piston position data, a flow rate of a fluid pumped by the displacement unit is estimated. A system correction factor is generated based on the first piston position data and the second piston position data. The estimated flow rate is adjusted based on the system correction factor.
