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.

Abstract: A device for measuring the viscosity of a fluid includes a viscosensitive unit through which the fluid flows under laminar flow conditions, a first turbulent flow flowmeter in series with the viscosensitive unit, and a second turbulent flow flowmeter shunting at least the viscosensitive unit. The flowmeters are adapted to determine the head loss .DELTA.p and the flowrate q of the fluid through the viscosensitive unit, the dynamic viscosity .mu. being given by the equation .mu.=.DELTA.p/kq where k is a constant dependent on the viscosensitive unit. The device is applicable to accurate measurement of fluid volumes.
