A sensor apparatus may include a channel structure configured to couple with an external element and a fluid conduit, such that the channel structure may receive a fluid, at least partially drawn through the external element from an ambient environment, and direct the fluid through the fluid conduit. A sensor may generate sensor data indicating a flow rate of the fluid through the fluid conduit based on monitoring a variation in a pressure at a location in hydrodynamic contact with the fluid conduit and in relation to an ambient pressure of the ambient environment. The sensor apparatus may enable generation of improved topography information associated with flows of fluid drawn from the external element based on measuring a local pressure at the location in hydrodynamic contact with the fluid conduit and determining the ambient pressure based on monitoring the local pressure over time.

In some embodiments, an apparatus includes a housing and a mount. The housing includes a cover portion and a base portion. The cover portion and the base portion define an interior. The housing defines an opening via which the interior can be accessed from a region external to the housing. The mount is coupled to the base portion and configured to maintain a position of a fillable component within the interior of the housing such that an elastomeric membrane of the fillable component is aligned with the opening defined by the housing and a reservoir of the fillable component is accessible by a needle via the opening and the elastomeric membrane.

Vaporization devices and methods of operating them. In particular, described herein are methods for controlling the power applied to a resistive heater of a vaporization device by measuring the resistance of the resistive heater at discrete intervals. Changes in the resistance during heating may be used to control the power applied to heat the resistive heater during operation. Also described herein are vaporization devices that are configured to measure the resistance of the resistive heater during heating and to control the application of power to the resistive heater based on the resistance values.
