Abstract

An aerosol generation system, a main unit (100) for the aerosol generation system, a cylinder (200), and a control system, as well as a method for determining the orientation of a liquid storage section (201) of the aerosol generation system. The aerosol generation system includes a liquid storage section (201) for holding a liquid aerosol forming matrix, a first pair of electrodes (320), a second pair of electrodes (330), and a control system. The liquid storage section (201) includes a first section (220) in fluid communication with a second section (230). The first pair of electrodes (320) is arranged adjacent to or within the first section (220) of the liquid storage section (201). The second pair of electrodes (330) is arranged adjacent to or within the second section (230) of the liquid storage section (201). The control system is configured to: measure the electrical charge between the first pair of electrodes (320); measure the electrical charge between the second pair of electrodes (330); and determine the orientation of the liquid storage section (201) based on the measured values ​​of the electrical charge between the first pair of electrodes (320) and the measured values ​​of the electrical charge between the second pair of electrodes (330).
