1. An electronic cigarette, comprising:
an atomizer;
a mass airflow sensor; and
a memory disposed on one of a first and second removable reservoir portion of the electronic cigarette, the memory including a non-transitory computer readable medium comprising computer executable instructions for controlling the atomizer of the electronic cigarette, the instructions executable by a processor to:
determine a first vaporization energy associated with a first liquid stored in the first removable reservoir portion;
determine a second vaporization energy associated with a second liquid stored in one of the first and second removable reservoir portion, when the second removable reservoir portion is connected to the electronic cigarette in place of the first removable reservoir portion, wherein the first vaporization energy is different than the second vaporization energy;
determine an amount of power to deliver to the atomizer over a period of time, based on either the first vaporization energy or the second vaporization energy and a type of wick associated with the atomizer, dependent on the particular reservoir portion connected to the atomizer, wherein the first vaporization energy or the second vaporization energy and information that identifies the type of wick is stored on the memory disposed on the particular reservoir portion connected to the atomizer; and
determine an amount of liquid remaining in the particular removable reservoir portion, based on a comparison between the total amount of power delivered to the atomizer and the total amount of vaporization energy associated with the first liquid or the second liquid, wherein the determination of the amount of liquid remaining in the removable reservoir portion is calibrated to the type of wick associated with the atomizer, as identified by the type of wick stored on the memory.
