at least one light source positioned on a movable element at first side of the infusion bag,
at least two light sensors positioned on the movable element at a second side of the infusion bag,
a control system including means to trigger the at least one light source, to receive signals from the at least two light sensors, and to transmit information to reporting and warning modules;
wherein when fluid is present in a line of travel of light from the at least one light source, the light is diffracted and detected by a first one of the at least two light sensors, and
when fluid is not present in the line of travel of light from the at least one light source, the light is not diffracted and is detected by a second one of the light sensors, the system thereby detecting a level of the fluid in the infusion bag, and
when the movable element reaches an end of its travel path, an alarm is triggered to alert the personnel monitoring the system to the fluid level.
