Abstract
The invention relates to a liquid-deficient monitor for a transparent pipeline. The monitor comprises a base on which photosensitive tube supports are fixedly arranged; a trough type photoelectric sensor is embedded into each photosensitive tube support; a groove is formed in each photosensitive tube support; an infusion tube is placed in the grooves; and a left microswitch and a right microswitch are fixedly arranged in positions, located at two ends of the infusion tube, on the base respectively. By means of the liquid-deficient monitor, whether a liquid flows in the infusion tube is monitored in real time through the trough type photoelectric sensors, so that fast and automatic detection is achieved; in order to prevent the trough type photoelectric sensor from failure which reduces the monitoring accuracy, the two trough type photoelectric sensors are mounted on the base, then the condition that one trough type photoelectric sensor cannot detect gas is avoided, and complementation is formed; and two microswitches are mounted on the base and used for detecting whether the infusion tube is placed into the liquid deficient monitor, and the false detection caused by the fact that the infusion is not placed into the monitor is prevented.
