Aerosol-generating system with pairs of electrodes

An aerosol-generating system comprising:

• two or more first pairs of electrodes adjacent to or in a first portion of a liquid storage;
• and
• two or more second pairs of electrodes adjacent to or in a second portion of the liquid storage;
• and
• a control system configured to
• determine an orientation of the liquid storage based on electrical quantities between the first pairs of electrodes and electrical quantities between the second pairs of electrodes without using a tilt sensor.

A method of determining an orientation of a liquid storage of an aerosol-generating system comprising:

• measuring a first electrical quantity between a first pair of electrodes adjacent to or in a first portion of the liquid storage;
• measuring a second electrical quantity between a second pair of electrodes adjacent to or in a second portion of the liquid storage, the first portion of the liquid storage being in fluid communication with the second portion of the liquid storage;
• and
• determining the orientation of the liquid storage based on the first electrical quantity the second electrical quantity and not based on a tilt sensor.
