摘要： A viscometer has an element to be immersed in a liquid the viscosity of which is to be monitored. The element is continuously rotated through a resiliently yieldable connection with the stator of a transducer rotated in a constant, selected rate. The rotor of the transducer turns relative to the stator as the connection yields or recovers as determined by the viscosity of the liquid which can vary continuously providing a continuously variable signal by which a digital readout is continuously operated.

摘要： 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.

摘要： A viscometer of the type has a chamber within which there are concentric, open ended cylindrical elements, one within the other. A drive is provided to rotate one of the elements and the inner element, which is free to turn, has one end of a readout rod connected axially thereto. The readout rod extends freely through a tube which seals the rod against the fluid flowing through the chamber and its other end is outside the viscometer with the rotor of a readout device connected thereto. The major percentage of the wanted torsional resistance against the turning of the inner element relative to the other element is provided by a resilient device which also ensures lateral stability for the inner element thus enabling the rod-sealing tube to offer but a minor percentage of such resistance. The readout rod is held by a bearing adjacent its outer end and close to the center of gravity of the rotor.
