First and second sensor cavities are disposed alongside the fluid channel, in parallel and separately connected to the fluid channel via first and second cutouts through the flowpath element, transverse to the centerline axis. First and second differential pressure sensors abut respective cavities, and are exposed to the fluid channel via the cutouts.
