Abstract
A method and apparatus for sensing the velocity of a fluid flow, especially within the boundary layer of a fluid flow path through a compressor. A reference flow under constant pressure is established through an orifice dividing two plenum chambers, and directed through a flow sensing opening in a probe positioned in the flow to be sensed. The flow sensing opening is slightly larger than the orifice. A relative pressure indicator connected to the two plenum chambers indicates the velocity of the sensed fluid flow. The flow sensing opening is arranged so that the normal reference flow of fluid therethrough is in the same direction as the normally expected flow direction of the flow to be sensed.
