A dosing device has a dosing tip for dispensing liquid medium and at least one pressure vessel with a pressurizing gas, in which an overpressure or a negative pressure can be set as a predefined pressure setpoint value of an internal pressure by a pressure regulator, wherein the internal pressure is set by the pressurizing gas acting on a first liquid medium. A bidirectional flow meter is provided to measure a quantity of the first medium that is moved by the internal pressure prevailing in the pressure vessel. Furthermore, a dosing valve is provided upstream of the dosing tip, which is adapted to enable or disable a flow of the first medium from the flow meter to the dosing tip. For precise dosing, the first medium is moved by a change in the predefined pressure setpoint value of the internal pressure of at least one pressure vessel, and the moved quantity of the first medium is measured by the flow meter.
