Claim 8:
9. An aerosol-generating device, comprising:
an air inlet;
an air outlet;
an air flow passage extending in a first direction between the air inlet and the air outlet;
a heating element in the air flow passage configured to heat an aerosol-forming substrate;
a first temperature sensor configured to measure a first temperature at a first position along the air flow passage;
a second temperature sensor spaced apart in the first direction from the first sensor configured to measure a second temperature at a second position along the air flow passage;
a controller configured to control an operational parameter of the device based on the measured first temperature and the measured second temperature;
a liquid storage portion comprising the aerosol-forming substrate; and
a pump configured to pump the aerosol-forming substrate from the liquid storage portion to the heating element,
wherein the operational parameter of the aerosol-generating device comprises a flow rate of the aerosol-forming substrate from the liquid storage portion to the heating element, and
wherein the controller is further configured to control the flow rate of the aerosol-forming substrate based on the measured first temperature and the measured second temperature.
