The system according to claim 12 wherein a distance between a central axis of said first hollow space relative to said central axis of said cylinder, and a distance of a central axis of said second hollow space relative to said central axis of said cylinder are the same. 14. The system according to claim 13 further including a second recess formed in said second half of said cylinder. 15. The system according to claim 3 wherein: said reflection member is cylindrical shaped and defines a central axis; and, the reflection member is arranged rotatably around said central axis in said fluid chamber of the receptacle. 16. The system according to claim 3 wherein said outer surface of the reflection member defines at least one second recess. 17. The system according to claim 16 wherein the reflection member is cylindrically shaped. 18. The system according to claim 17 wherein said first recess and said at least one second recess are formed about the circumference of the cylindrically shaped reflection member. 19. The system according to claim 18 wherein exactly two recesses are formed on opposite sides of the cylindrically shaped reflection member. 20. The system according to claim 1 wherein said reflection member has an inhomogeneous distribution of mass. 21. The system according to claim 1 further including a transport window formed in a wall of said receptacle, said beam of light being directed into said fluid chamber of the receptacle through said transparent window. 22. The system according to claim 21 wherein said window defines a blunt projection extending into an interior of said receptacle. 23. The system according to claim 1 wherein said reflection member is pivotally connected at an articulation at a wall of the receptacle by a rigid suspension member, the reflection member being movable in a circular path around an articulated axis defined at said articulation point. 24. The system according to claim 1 further including a guide way adapted to guide said reflection member in movement relative to said receptacle based on said level of the fluid within the fluid chamber of the receptacle. 25. The system according to claim 1 further including: a suspension member for attaching said reflection member to a lid of said receptacle, said reflection member moving together with said level of the fluid contained within said fluid chamber of the receptacle. 26. The system according to claim 25 wherein an underside of said reflection member defines a recess, and walls of said recess re-direct said light beam from said light source. 27. The system according to claim 1 wherein said reflection member is a prism shaped float movable relative to the receptacle based on said level of the fluid contained within the receptacle. 28. The system according to claim 27 wherein said prism shaped float is adapted to re-direct said beam of light from said light source into said light detector when said receptacle is empty of said fluid. 29. The system according to claim 27 further including a guide way in the fluid chamber of the receptacle, said guide way guiding said reflection member along a straight line movement path within said receptacle. 30. An ink cartridge for use with an associated ink jet printer including a light source directing a beam of light in a path toward said cartridge and a light detector positioned to receive a reflected beam of light from the cartridge and adapted to determine a level of fluid contained within the cartridge based on an intensity of the reflected beam of light, the ink cartridge comprising: a set of receptacle walls defining a fluid chamber for containing ink within the cartridge; and, a reflection body floatable on said fluid contained within the cartridge, the reflection body being movable relative to a receptacle wall of the cartridge based on a l
