Zusammenfassung:	A flow sensor assembly that may include features that help prevent moisture from reaching a sensor die of the flow sensor assembly. In some cases, such features may include a bypass channel that is configured to reverse the direction of the flow of fluid at least once upstream of the sensor die. In some cases, an encapsulant may cover one or more bond pads of the sensor die. In some cases, an output of the flow sensor assembly may be a raw sensor output signal produced by the one or more sensor elements of the sensor die, without significant processing of the raw sensor signal.
