摘要：
A method and pump that accurately senses air in a fluid delivery line pulses or activates and deactivates the air sensor(s) multiple times during the pumping phase of the fluid delivery cycle and can generate alarms based upon a single indication or a cumulative indication of air in the line. The pump can include multiple air sensors spaced along the delivery line so that the method can use the multiple signals therefrom to distinguish real moving air bubbles from false positives and/or air bubbles adhered to the inner wall of the line.
