1. A method of determining a property of a flow of an aerosol generation system for generation of an aerosol from an aerosol-forming precursor, the aerosol generation system comprising an electrically operated heating system to heat said precursor to generate the aerosol, and a flow path for transmission of flow, including the aerosol, to a user, wherein the heating system is arranged in fluid communication with the flow path, the method comprising:
measuring a property of electrical energy through the heating system over a time period, wherein the time period is a portion of a duration of an inhale, and wherein the measured property of the electrical energy is any one of current, electric potential, or power;
measuring a quantitative feature of a fluctuation of said measured property of the electrical energy during the time period, the measured property changing during the time period;
selecting, based on the quantitative feature of the fluctuation, one from a plurality of different stored relationships between the measured property of the electrical energy and a property of the flow; and
determining the property of the flow based on said selected relationship.
