Filed:

Nov 29, 2000

Appl. No.:

09/725744

Inventors:

Frederick P. Boyle - Kirtland OH
Gary Garvin - Mentor OH
Klaus-Werner Damm - Chagrin Falls OH
Daniel H. Heath - Ravenna OH
Herman F. George - Chardon OH
Peter J. Moore - Hampshire, GB

Assignee:

The Lubrizol Corporation - Wickliffe OH

International Classification:

G01N 1114

US Classification:

73 5434, 73 5401, 73 5435

Abstract:

A viscometer for sensing or characterizing the stress required to shear a fluid at a given rate includes a pair of members coaxially mounted for relative rotation. Between the members is an annular gap defining a flow path for the fluid. The flow path is configured such that during differential rotation of the members, fluid is caused to flow through the annular gap that is a function of the differential rotation and the viscosity of the fluid. A sensor measures the torque or torque equivalent required to achieve such differential rotation between the members.
