Abstract: An aerosol-generating system includes a liquid storage for holding a liquid aerosol-forming substrate, a first pair of electrodes, a second pair of electrodes and a control system. The liquid storage includes a first portion in fluid communication with a second portion. The first pair of electrodes is adjacent to or in the first portion of the liquid storage. The second pair of electrodes is adjacent to or in the second portion of the liquid storage portion. The control system is configured to measure an electrical quantity between the first pair of electrodes, measure an electrical quantity between the second pair of electrodes, and determine the orientation of the liquid storage portion based on the electrical quantity between the first pair of electrodes and the electrical quantity between the second pair of electrodes.

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.
