Abstract: A fluid sensing apparatus and method for detecting pressure and a presence of a bubble within a fluid tube. The fluid sensing apparatus comprises a housing configured to receive a portion of the fluid tube and to house a pressure sensor and an ultrasonic transmitter. The pressure sensor is positioned adjacent the fluid tube and is configured to receive a pressure sensor signal, which correlates to a detected pressure differential within the fluid tube.

The pressure sensor receives both the ultrasonic waves and the pressure sensor signal, and subsequently transmits an output signal to the controller. In a presence of the detected pressure differential or the bubble within the fluid tube, the output signal will exhibit a DC shift or a distortion of signal characteristics of the output signal, respectively.
