Abstract
A flow-sensing probe adapted to be mounted in a conduit for indicating the flow rate of a fluid passing through the conduit. The probe has forward openings facing in the direction of fluid flow, and rear openings disposed at an angle of about one hundred and ten degrees with respect to the forward openings. Pressures sensed by the forward and rear openings are used to indicate volumetric flow by using a flow coefficient that is independent of Reynold's number.
