Embodiments relate generally to a system comprising a flow sensor assembly. The flow sensor assembly includes a housing defining a flow channel. The flow channel has an inlet serpentine portion fluidly coupled to an inlet port, and an outlet serpentine portion fluidly coupled to an outlet port. The housing further defines a sensor chamber fluidly coupling the inlet serpentine portion to the outlet serpentine portion, where the sensor chamber has a split planar region. The flow sensor assembly further includes a sensor die located proximate to the split planar region and configured to sense a measure related to a flow rate of a fluid.
