Claim 16:
17. A method of controlling an aerosol-generating device, the aerosol-generating device comprising a heating element in an air flow passage extending in a first direction, a liquid storage portion comprising an aerosol-forming substrate, and a pump configured to pump the aerosol-forming substrate from the liquid storage portion to the heating element, the method comprising:
measuring a first temperature at a first position along the air flow passage;
measuring a second temperature at a second position along the air flow passage, wherein the second position is spaced apart in the first direction from the first position; and
controlling an operational parameter of the device, based on the measured first temperature and the measured second temperature, wherein the operational parameter of the device comprises a flow rate of the aerosol-forming substrate from the liquid storage portion to the heating element, and wherein the controlling the operational parameter of the device comprises controlling the flow rate of aerosol-forming substrate based on the measured first temperature and the measured second temperature.
