An apparatus for measuring the flow of aerosol from an aerosol delivery device, such as an e-cigarette. The apparatus comprises a main body defining a measurement chamber in a flow path extending from an aerosol-input end of the apparatus to a mouthpiece end of the apparatus. When in use, aerosol drawn into the aerosol-input end of the apparatus from an aerosol delivery device flows along the flow path and through the measurement chamber and out through the mouthpiece end of the apparatus. The apparatus further comprises a sensor for measuring a drop in pressure along a part of the flow path within the measurement chamber to allow characteristics of aerosol flow along the flow path to be measured, (e.g. flow rate, puff volumes, etc.). Thus, a user may use the aerosol delivery device (i.e. puff aerosol generated by the aerosol delivery device) via the monitoring apparatus to allow characteristics relating to the delivery of aerosol to be monitored during use (e.g. flow rate, puff volumes and timings, etc.). The apparatus further comprises a diffusion element arranged between the aerosol-input end of the apparatus and the measurement chamber to diffuse the flow of aerosol entering the flow path from an aerosol delivery device before it reaches the measurement chamber. The diffusion element may, for example, comprise an extension tube providing an extended section of flow path between the aerosol-input end of the apparatus and the measurement chamber. |
