Meter for measuring the volume of a flowing fluid

摘要

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.
