Abstract
A sliding cover for a liquid delivery device, such as a cap () for a pen injector (), incorporates a set of sensors including an optical sensor () with an output which changes during uncapping or capping motions on passing of a plunger () of the pen injector. This output is used together with a position sensor () to determine the position of the plunger along a cylinder () of the liquid delivery device. By monitoring changes in the plunger position, the quantity of dosages delivered by the liquid delivery device can be determined, displayed, stored and/or transmitted to an external device for further data processing or storage. Preferred implementations of the invention employ optical sensors with a converging beam (), and/or position sensors employing linear potentiometer strips ().
