There is provided an apparatus for measuring the shear stress of a fluid wherein the shear stress is determined by measuring the movement of one end of a substantially rigid lever with the other end having the active face forming the shear stress measurement surface.

Method and apparatus for measuring shear stress

There is provided a method and apparatus for measuring the viscosity and other rheological properties of a viscoelastic fluid wherein the fluid flows through a fluid channel which has a plate mounted therein, the plate having a surface which is substantially parallel to a wall surface defining the channel and the plate is moved with respect to the wall to thereby subject fluid between the wall surface and the plate to a shearing deformation, and subsequently measuring the shear stress of the fluid at the wall when subjected to the shearing deformation.

Method and apparatus for measuring rheological properties of fluid

A method is disclosed for measuring the shear stress of a viscoelastic fluid wherein the force measured on a plate exerted by the fluid flowing coplanar therewith is measured.
