Flow sensor assembly with integral bypass channel

A flow sensor assembly, comprising:

• a housing defining at least part of an inlet flow port, an outlet flow port, a fluid channel extending between the inlet flow port and the outlet flow port, and a bypass channel, wherein the bypass channel including an upstream tap in fluid communication with the fluid channel upstream at a first location, and a downstream tap in fluid communication with the fluid channel at a second location, the bypass channel having a generally s-shaped curve adjacent to the upstream tap and/or the downstream tap, wherein a pressure differential between the first location and the second location drives at least a portion of a fluid through the bypass channel;
• and
• a flow sensor positioned in fluid communication with the bypass channel, and configured to sense a measure related to a flow rate of a fluid flowing through the bypass channel, which is related to the flow rate of a fluid flowing through the fluid channel.
