Abstract

Aerosol provision system comprising (10) a reservoir (3) holding liquid of a first liquid type; a vaporiser (4) located in an air flow path; and a controller (28) configured to: determine a mass of aerosol generated by the vaporiser during a puff taken by a user, from a power level value and a puff duration value, and using an equation relating power level and puff duration to mass of aerosol for an aerosol provision system with a vaporiser located in a specified configuration of air flow path and with liquid of a specified liquid type different from the first liquid type; and estimate an amount of liquid in the reservoir after the puff; wherein the airflow path is modified compared to the specified configuration in order to provide a different air flow past the vaporiser and thereby compensate for a difference in vaporisation behaviour.
