| 1. An apparatus for measuring fluid viscosity in a conduit, comprising:
a viscosity turbine disposable in the conduit, wherein the viscosity turbine has a central portion and a plurality of blades
extending therefrom, and the blades are adapted such that fluid flowing through the conduit induces no rotational movement
of the viscosity turbine;
a drive device for rotating the viscosity turbine; and
a measuring device for measuring fluid drag on the viscosity turbine, wherein the drag is a function of the viscosity of the
fluid in the conduit.
