Abstract
An aerosol-generating system includes a liquid storage portion for holding a liquid aerosol-forming substrate; a pair of electrodes arranged adjacent to or in the liquid storage portion; a sensor configured to sense an orientation of the liquid storage portion; and a control system configured to, measure an electrical quantity between the pair of electrodes, receive orientation information from the sensor, and determine an amount of liquid aerosol-forming substrate held in the liquid storage portion based on electrical quantity information measured between the pair of electrodes and the orientation information received from the sensor, wherein the liquid storage portion has a length and the pair of electrodes extend substantially the length of the liquid storage portion.
