Abstract
The vaporizer device includes a reservoir configured to contain a vaporizable material. The vaporizer device further includes a heating element configured to vaporize the vaporizable material. The vaporizer device further includes a thermal flow sensor configured to measure a mass flow rate of the vaporizable material across the surface of the thermal flow sensor. The thermal flow sensor is positioned along an airflow path between the heating element and an outlet of the vaporizer device. The thermal flow sensor includes a self-cleaning element configured to remove a liquid accumulated on the surface of the thermal flow sensor by at least evaporating the liquid. The self-cleaning element is activated in response to detecting an event that activates a cleaning cycle of the thermal flow sensor.
