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