Abstract
A flowmeter of the fluid oscillator type having a fluid jet which oscillates at a frequency indicative of flow rate. A linear flow rate vs. frequency output characteristic is obtained by use of a fluid accelerating means in the form of a two-dimensional sharp edge orifice. The orifice has an aspect ratio selected to give a constant coefficient of discharge throughout an extended flow range including laminar and turbulent flow conditions.
