Title
(EN) MULTI-SURFACE VISCOSITY MEASUREMENT
(FR) MESURE DE VISCOSITÉ DE SURFACES MULTIPLES
Abstract
(EN)
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.
(FR)
Des systèmes et des procédés permettant de mesurer la viscosité d'un fluide peuvent faire appel à une coupelle de rotor comportant une chambre interne ; à une première bobine disposée rotative à l'intérieur d'une première région de la chambre interne ; et à une seconde bobine disposée rotative à l'intérieur d'une seconde région de la chambre interne, la seconde bobine tourne par rapport à la première bobine sur la base d'une différence de viscosité de fluide dans la première région et la seconde région.
