Abstract

An adapter for a sensitive viscometer. It provides increased drag at low shear rates to increase the accuracy. There is an inverted cup shaped rotor that cooperates with an annular shaped stationary container for the fluid to be measured. The annular shape of the container provides reaction surfaces with the fluid on both the inner and outer surfaces of the rotor. And, there is a reservoir in the stationary container with an overflow edge, so that the quantity of fluid to be measured is accurately metered.
