Abstract
Systems and methods for measuring the viscosity of a fluid may comprise a rotor cup having an inner chamber; a first bob rotatably disposed within a first region of the inner chamber; and a second bob rotatably disposed within a second region of the inner chamber, wherein the second bob rotates relative to the first bob based on a difference in viscosity of fluid in the first region and the second region.
Claims20
A system for measuring the viscosity of a fluid, comprising:
- a rotor cup having an inner chamber;
- a first bob rotatably disposed within a first region of the inner chamber;
- and
- a second bob rotatably disposed within a second region of the inner chamber, wherein the second bob rotates relative to the first bob based on a difference in viscosity of fluid in the first region and the second region.
A method for measuring the viscosity of a fluid, comprising:
- containing the fluid within a rotor cup having a first bob rotatably disposed within a first region of the rotor cup and a second bob rotatably disposed within a second region of the rotor cup;
- rotating the rotor cup and the fluid disposed therein;
- sensing a first property of the first bob;
- sensing a second property of the second bob;
- determining a first viscosity of the fluid in the first region based on the first property of the first bob;
- and
- determining a second viscosity of the fluid in the second region based on the second property of the second bob.
A viscometer, comprising:
- a rotor cup;
- a plurality of bobs rotatably disposed within the rotor cup, wherein the plurality of bobs includes a proximate bob and a distal bob;
- a plurality of measurement regions defined within the rotor cup, wherein discrete bobs are disposed within discrete measurement regions;
- and
- a first sensor capable of detecting a first property of the proximate bob indicative of the viscosity of the fluid within a proximate measurement region and a second sensor capable of detecting a second property of the distal bob indicative of the viscosity of the fluid within a distal measurement region.
