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.
