ABSTRACT:
A turbine viscometer for measuring the viscosity of fluid flowing through a conduit, such as a pipe or manifold. The viscometer has a viscosity turbine positionable in the pipe or manifold. The viscosity turbine has a central portion and a plurality of blades extending therefrom such that fluid flow does not induce any rotational movement of the viscosity turbine. The viscometer also has a drive device for rotating the viscosity turbine so that fluid drag on the viscosity turbine can be measured to determine the viscosity of the fluid. In one embodiment, the drive device creates a rotational magnetic field around the viscosity turbine so that it is rotated. In a second embodiment, the drive device is a drive turbine connected to the viscosity turbine and rotated by fluid flowing through the pipe or conduit.
