A flow calibrating method is proposed. The flowmeter is placed in a flow controlled hydraulic flow, and the time necessary to displace a hydraulic piston between electronically controlled positions is measured. The electronic measurement allows for an easy automation. The accuracy of the calibration is 0.05% for flows between 0.1 and 600 lt/min.
