Abstract
A flowmeter of the fluid oscillator type having a fluid jet which oscillates at a frequency indicative of flow rate. By elimination of wall attachment effects and use of a proportional type amplifier, the range of the flowmeter is substantially extended beyond the limit of turbulent flow conditions. Linearity is improved by use of a differential pressure type of fluid jet control and the range may be further extended by use of multiple amplifier stages.
