  • Patent number: 11857760
    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. A controller transmits a drive signal to the ultrasonic transmitter, which emits ultrasonic waves through a portion of the fluid tube and to the pressure sensor. 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.
