Abstract: Presented are dual-passage fluid couplers with integrated fluid sensors, methods for using/making such fluid couplers, and motor vehicles equipped with such fluid couplers. A quick-connect (QC) fluid coupler includes a sensor assembly with a sensor housing containing a sensing device that monitors fluid flow, and a main connector body with opposing inlet and outlet ends having respective inlet and outlet ports. The main connector body contains a sensor chamber attaching thereto the sensor housing, and a primary fluid chamber that extends from the inlet end to the outlet end of the main connector body and fluidly connects the inlet and outlet ports. Interposed between the primary and sensor chambers is a secondary fluid chamber that is fluidly connected to the sensor chamber via a sensor port and to the primary fluid chamber via a bleed port upstream from the sensor port and a merge channel downstream from the sensor port.
