Abstract
A device for dispensing or receiving a liquid volume includes a liquid reservoir having an outlet, a pressure generator which provides a compressible enclosed gas volume of a constant amount of substance with a pressure, wherein the gas volume is in direct or indirect fluidic contact with the liquid in the liquid reservoir, a dosing device coupled to the outlet of the liquid reservoir and operable in order to enable the liquid to pass the outlet, a pressure sensor arranged to measure a current pressure in the gas volume and to output an output signal indicating the current pressure in the gas volume and a controller coupled to the pressure generator, the dosing device and the pressure sensor.
