1. An aerosol-generating system, the system comprising:
a pump configured to deliver an aerosol-forming substrate to a vaporizer;
a puff sensor in an airflow path, the puff sensor configured to sense a puff; and
a controller configured to determine a puff intensity based on an output from the puff sensor and adjust a delivery flow rate of the pump in response to the determined puff intensity.
