The present invention relates to a cartridge for an aerosol-generating system, the cartridge comprising a sensor (34A,B) comprising a capacitor with a first capacitor plate (34A) and a second capacitor plate (34B), a liquid storage portion (38A,B) for holding a liquid aerosol- forming substrate and a vaporiser, wherein the liquid storage portion (38A,B) is arranged between the first capacitor plate (34A) and the second capacitor plate (34B), wherein the permittivity of the liquid storage portion (38A,B) changes upon a change of the volume of the liquid aerosol-forming substrate held in the liquid storage portion (38A,B), wherein the sensor (34A,B) is configured to measure the capacitance of the capacitor, and wherein the measured capacitance relates to a corresponding permittivity of the liquid aerosol-forming substrate held in the liquid storage portion (38A,B) so that the amount of the volume of the liquid aerosol-forming substrate held in the liquid storage portion (38A,B) is determinable from the measured capacitance. The present invention further relates to an aerosol- generating system that comprises the cartridge. The present invention further relates to a method for measuring a capacitance from which the volume of a liquid aerosol-forming substrate held in a liquid storage portion (38A,B) is determinable. |
