    Abstract: A aerosol-generating system includes a liquid storage portion, a liquid pressure sensor within the liquid storage portion, and a control unit that is in communication with the pressure sensor. The aerosol-generating system further includes an atmospheric pressure sensor in communication with the control unit. The atmospheric pressure sensor is configured to sense the atmospheric pressure of the environment. The control unit is configured to receive the pressure signals from the liquid pressure sensor and the atmospheric pressure sensor. The control unit is further configured to determine the fill level of the liquid aerosol-forming substrate based on a comparison of the pressure signals from the liquid pressure sensor and the atmospheric pressure sensor.

    Abstract: The present disclosure is related to a level and/or density sensor for vessels suitable for storing liquids, in particular barrels or vats, more in particular barrels or vats for storing or producing wine. The hydrostatic pressure differential sensor for measuring volume and/or density disclosed herein comprises a main body; a tube for diving into the liquid; a hydrostatic pressure differential sensor; an air injector for injecting air into said tube; wherein the tube is coupled to the main body; wherein the hydrostatic pressure differential sensor has two inlets, a first inlet airtight connected to the upper top of said tube, configured so that the tube maintains air present in the interior thereof when dived into the liquid, and a second inlet for communicating with the interior of the vessel.
