ABSTRACT:
An apparatus and method for determining the viscosity and density of a fluid by circulating the fluid upward through a tube, having a cup positioned therein, at a fluid flow rate which suspends the cup in a stationary equilibrium position. Thereafter, a weight is added to the cup and a new fluid flow rate which suspends the weighted cup in the equilibrium position is determined. The density and viscosity of the fluid are determined as a function of the two fluid flow rate values and the physical characteristics of the apparatus.
