Abstract
There is provided an electrically operated aerosol generating system for receiving an aerosol-forming substrate. The system includes a liquid storage portion for storing liquid aerosol-forming substrate, an electric heater including at least one heating element for heating the liquid aerosol-forming substrate, and electric circuitry for determining depletion of liquid aerosol-forming substrate heated by the heater based on a relationship between a temperature of the heating element and power applied to the heating element. There is also provided a method in an electrically operated aerosol generating system including a liquid storage portion for storing liquid aerosol-forming substrate and an electric heater including at least one heating element for heating the liquid aerosol-forming substrate, the method including determining depletion of liquid aerosol-forming substrate heated by the heater based on a relationship between a temperature of the heating element and power applied to the heating element.
