Abstract
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.
