description A drug delivery system includes a drug delivery device for dispensing a drug from a reservoir with a device housing extending in an axial direction, a movable dispensing member, a magnetic element with a permanent magnetization coupled the dispensing member, and an electronic module for monitoring a dispensing process executed by the drug delivery device and releasably attachable to the device housing. The electronic module includes a module body, a magnetic field sensor unit and a controller. The sensor unit is adapted to measure an absolute rotational position and an absolute axial position of the magnetic element. The controller is configured to determine on basis of both the absolute rotational and the absolute axial position a fill level or a total amount of dispensed drug.
