Abstract
A meter for measuring the volume of a flowing fluid includes a viscosensitive unit through which the fluid flows under laminar flow conditions, a first fluidic oscillator in series with the viscosensitive unit, and a second fluidic oscillator shunting at least the viscosensitive unit. The viscosensitive unit and the fluidic oscillators are adapted to determine the viscosity of the fluid so as to apply to the fluid volume measured by the fluidic oscillators a correction dependent on the Reynolds number.
Claims6
A meter for measuring the volume of a flowing fluid, wherein said meter comprises:
- a viscosensitive unit through which said fluid flows under laminar flow conditions,
- a first fluidic oscillator in series with said viscosensitive unit, and having a fluid frequency output
- a second fluidic oscillator shunting at least the viscosensitive unit, and having a fluid frequency output and
- means coupled to said fluid frequency outputs of said first and second fluidic oscillators determining a measured fluid volume and a viscosity of the fluid, and for applying to the measured fluid volume a correction that depends on Reynolds number.
