Sensing system for detecting a piston in a medical fluid container

A sensing system for determining a position of a plunger within a fluid container. The sensing system includes a light source, a light detector and a controller. The light source is configured to emit light into a barrel wall of the fluid container so that the barrel wall serves as a waveguide to guide the light to travel therein in an axial direction.
