A fluid flow system and a method for detecting air bubble and liquid are provided. The fluid flow system comprises a force sensor configured to monitor at least one of an air bubble or an occlusion in a flow tube. The fluid flow system comprises a controller to execute the method. The controller is configured to monitor an output signal of a force sensor of the fluid flow system, and the output signal comprises an Alternating Current (AC) component and a Direct Current (DC) component, and detect a change in the output signal to a new output signal based on a number of transitions to the new output signal, and a time duration of the new output signal. The controller compares the change in the output signal with one of a predefined number of transitions or a predefined time and determines a new threshold when the change in the output signal exceeds one of the predefined number of transitions or the predefined time.

Fluid flow system for bubble and fluid detection

Systems, apparatuses, and methods are disclosed for sensing a force applied by an external source. An example system comprises a substrate comprising a plurality of electrical contact pads disposed on a first surface of the substrate. The system further comprises a force sensing device disposed on a second surface of the substrate, the second surface opposite the first surface. The system further comprises a housing disposed on the second surface of the substrate. The housing defines an aperture that provides a common coupling interface. The common coupling interface provides a common path for the force to be transmitted to the force sensing device either through a first coupling or a second coupling different from the first coupling.
