Abstract :
An air bubble detection system is presented, suitable for medication drug delivery system that must avoid air bubble beyond certain limits. The suggested approach is based on transmission of an acoustic (ultrasonic) wave through the active detection area of the fluid media and analysis of its impact on the acoustic wave. Physical operation principle and design considerations are provided as well as the cross correlation based signal processing procedures. Experimental results are provided, showing good agreement with the theory
