A device for delivering fluid to a patient including an exit port assembly adapted to connect to a transcutaneous patient access tool, a flow path extending from the exit port assembly, and a flow condition sensor assembly. The sensor assembly includes a resilient diaphragm having a first surface positioned against the flow path, a chamber wall defining a sensor chamber adjacent a second surface of the diaphragm, and at least one sensor arranged to provide a threshold signal when the second surface of the diaphragm expands into the chamber in response to at least one predetermined fluid flow condition occurring in the flow path. The sensor includes a first electrode secured on the diaphragm, a second electrode positioned in a fixed location with respect to the first electrode, and an impedance meter connected between the electrodes.
