Abstract
A viscometer (10) has a spindle (12) mounted on a rotatable shaft (14) which is, in turn, contained in a tubular rotatable shaft (16) which is within a fixed hollow shaft (18). The latter is suspended from a flange (20) that mates with a flange (22) of an access port (24) of a reactor vessel (RV). There is a base for an external tower (21) that carries a motor (M) and gearing (G) to drive the rotatable shafts (14, 16). A torque interconnection between the rotatable shafts allows angular deflection between them and a transducer (28) picks up such deflection.
