Abstract
An electrically operated aerosol-generating system may include a liquid storage portion configured to store a liquid from which aerosol may be generated, an electric heater, a capillary wick extending between the liquid storage portion and the electric heater and configured to convey liquid from the liquid storage portion to the electric heater and electric circuitry connected to the electric heater. The electric circuitry may be configured to: activate the electric heater for a first heating time period in response to an input to vaporize liquid in the capillary wick, activate the electric heater for a second heating time period upon the elapse of a first cooling time period after the first heating time period, record a temperature measurement of the electric heater during the second heating time period, and determine an amount of liquid in the liquid storage portion based on the temperature measurement.
