摘要： A fluid level detection system (50) for ink in a printing press (10) having a vessel (58) having walls (60) defining a chamber (62), an elongated rotatable shaft (64) in the chamber (62), a motor (66) for rotating the shaft (64), an elongated flexible blade (68) affixed to the shaft (64) such that the motor (66) rotates the blade (68), and a proximity sensor (72) adjacent the walls (60) of the vessel (58) to detect the rotating blade (68) in the absence of ink at the level of the blade (68), with the blade (68) flexing in the presence of ink such that the sensor (72) does not detect the blade (68).
