System and method for capturing dose information

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 plurality of magnetic beads having a density less than a density of a medicament within the medicament vial, the plurality of magnetic beads being disposed within the medicament vial and floating within the 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 beads within the medicament vial.

• wherein the medicament volume sensor comprises a capacitance sensor having capacitance as a continuous function of a medicament level within the medicament vial attached to a sidewall of the medicament vial;
• wherein a number of the plurality of magnetic beads is sufficient to substantially cover an exposed surface of the medicament within the vial.
