Title: Differential pressure flow sensor

Abstract: The fluid flow meter of the present invention includes a ramp inclined tothe surface of a vessel so as to form a recess in the surface. A dynamicport surface extends from the lower end of the ramp to the surface of thevessel. A dynamic port is formed in the surface of the vessel, and astatic port is formed in the ramp. The differential pressure between thedynamic and static ports is measured and is related to the flow velocityof fluid over the surface. The inventive flow meter has advantages ofreduced drag, reduced likelihood of fouling and reduced likelihood ofimpact damage compared to conventional flow meters.
