摘要：A device for measuring the viscosity of a fluid includes a viscosensitive unitthrough which the fluid flows under laminar flow conditions, a first turbulent flowflowmeter in series with the viscosensitive unit, and a second turbulent flow flowmetershunting at least the viscosensitive unit. The flowmeters are adapted to determine thehead loss &Dgr;p and the flowrate q of the fluid through the viscosensitive unit, thedynamic viscosity &mgr; being given by the equation &mgr;=&Dgr;p/kq where k is aconstant dependent on the viscosensitive unit. The device is applicable to accuratemeasurement of fluid volumes.
