20 . The e-liquid cartridge of claim 1 adapted so that the level of or quantity of e-liquid in the cartridge or used by the cartridge can be measured or inferred so that a timely signal indicating that a replacement cartridge is needed can be generated.

21 . The e-liquid cartridge of claim 20 in which the signal is sent to a connected smartphone which in turn connects to an e-fulfillment platform.

22 . The e-liquid cartridge of claim 20 that interacts with an ultrasonic range that measures how much e-liquid is left in the cartridge or whether a replacement is needed.

23 . The e-liquid cartridge of claim 20 that interacts with a tilt sensor to detect the angle of the cartridge and whether the e-liquid in the cartridge closes an electrical circuit between different electrical contacts at different levels within the cartridge.

24 . The e-liquid cartridge of claim 20 that interacts with a weight sensor that weighs the cartridge.

25 . The e-liquid cartridge of claim 20 that interacts with a capacitive sensor that detects the level of e-liquid in the cartridge.

26 . The e-liquid cartridge of claim 20 that interacts with an air pressure sensor at the top of a flexible tube whose bottom is held just above the bottom of the cartridge.

27 . The e-liquid cartridge of claim 1 in which the e-liquid includes nicotine and the PV is not a medicinal device but instead a device that in normal use replaces cigarettes, with the e-liquid being vapourised in the PV and the vapour inhaled to replicate or replace the experience of smoking a cigarette.
