An electronic cigarette device has a vapor flow channel arranged to guide a generated vapor to a mouthpiece opening, and a sensor arranged in the vapor flow channel to determine a temperature in the vapor flow channel at a position physically displaced from an atomizer. The electronic cigarette device further includes one or more processors configured to retrieve from the sensor a measured temperature data set including one or more temperature measurements as a function of time, compare the measured temperature data set with predetermined temperature data, wherein the predetermined temperature data is indicative of the temperature of the vapor in the vapor flow channel of the electronic cigarette device at different fluid transfer element saturation levels, and determine and perform a further action based upon the comparison.

A portable loose-leaf material vaporizer 1 comprises a heating chamber 20 for housing loose leaf material and vaporizing one or more active agents from the loose-leaf material, a mouthpiece 3 for withdrawal of the one or more active agents vaporized from the loose-leaf material, and a processing unit. The processing unit is configured to control temperature of the heating chamber 20 and to estimate a dosage of the one or more active agents withdrawn from the vaporizer 1 based on a mathematical model. The mathematical model relates vapor generating time and loose-leaf material properties, and optionally temperature of the heating chamber 20, to the dosage of the one or more active agents withdrawn or to be withdrawn from the vaporizer 1.
