Abstract
Viscosity assemblies may be used to determine the viscosity of a sample fluid at a surface location under one or more downhole conditions prior to pumping or flowing of the sample fluid downhole. A viscosity assembly may include a bob assembly disposed in a container that includes a bob disposed about a magnet rotor that rotates when a shear force is applied by the flow of the sample fluid in the container. A stator coil may receive a control signal that induces a force or a voltage that causes the magnet rotor to rotate the bob by a predetermined distance to position the bob from the rotated position back to the initial position.
