Abstract
A fluidic flow meter comprising a fluidic oscillator having an oscillation chamber, a power nozzle for issuing a jet of fluid into the oscillation chamber, an outlet for issuing fluid from the oscillation chamber. A bendable fiber optic wave guide loop has a section adapted to lose light as a result of flexing or bending is mounted in a flow path in the oscillation chamber and subjected to oscillatory flow of the fluid. Light is injected into one end of the fiber optic wave guide and a detector senses the oscillatory loss of light in the fiber optic wave guide as a measure of fluid flow through the fluidic oscillator.
