Abstract
In some examples, a fluid analysis device (FAD) comprises a fluid chamber comprising an agitator and a shear stress sensor exposed to a surface within the fluid chamber.
Claims4
A fluid analysis device (FAD), comprising:
- a fluid chamber comprising an agitator, wherein the agitator comprises a rotating bob;
- and
- a micro-electro-mechanical system (MEMS) shear stress sensor having a fluid contact surface exposed to an opposing surface within the fluid chamber, wherein the MEMS shear stress sensor is positioned in a recess located on an outer surface the agitator such that the fluid contact surface is positioned about flush with the outer surface of the agitator.
A fluid analysis device (FAD), comprising:
- a fluid chamber comprising an agitator;
- and
- a micro-electro-mechanical system (MEMS) shear s tress sensor exposed to a surface within the fluid chamber, wherein the MEMS shear stress sensor is positioned on the agitator, wherein the agitator comprises a rotating sleeve with a stationary bob positioned inside the rotating sleeve, wherein the MEMS is positioned on the bob.
A fluid analysis device (FAD), comprising:
- a fluid chamber comprising an agitator;
- and
- a shear stress sensor exposed to a surface within the fluid chamber,
- wherein the agitator comprises a sleeve,
- wherein the FAD comprises a bob positioned inside a sleeve,
- wherein the bob comprises first and second surfaces corresponding to different diameters of the bob, wherein the shear stress sensor is aligned parallel with the first surface, and wherein the FAD comprises another shear stress sensor aligned parallel with the second surface.
