摘要：
A calibration device for the calibration of a flow meter is provided. The calibration device comprises a piston. The calibration device also has a calibration volume, and the piston is located in the calibration volume. The calibration device also has a first valve. The first valve is positioned downstream of the calibration volume. The calibration device also has a sensor, and the sensor is configured to provide an indication of the fluid volume in the calibration volume. The calibration device also has at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the calibration device to open and close the first valve.
