1. A system for capturing delivered dose information, comprising:
a medicament vial having a medicament volume sensor attached to a sidewall of the medicament vial;
a processor;
a memory comprising instructions adapted to control the processor to receive medicament volume measurements from the medicament volume sensor, and to determine a difference in volume prior to a dose delivery and after the dose delivery; and
a magnetic ring having a diameter substantially similar but smaller than an inner diameter of the medicament vial or a plurality of magnetic beads, the magnetic ring or plurality of magnetic beads being disposed in the medicament vial, and having a density less than a density of a medicament in the medicament vial; and wherein the medicament volume sensor comprises a magnetic sensor in proximity to the medicament vial to detect a location of the magnetic ring or plurality of magnetic beads within the medicament vial.
