Abstract
Aerosol provision system (10) comprises a reservoir (3) holding liquid to be vaporised, the liquid being of a first liquid type; a vaporiser (4); 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 same type of vaporiser 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 a composition of the first liquid type is modified compared to the specified liquid type such that the first liquid type has a same vaporisation behaviour as the specified liquid type.
