Title
(EN) DEVICE FOR MEASURING THE VISCOSITY OF A FLUID, IN PARTICULAR FOR ACTIVE FLUIDS
(FR) DISPOSITIF DE MESURE DE LA VISCOSITE D'UN FLUIDE, EN PARTICULIER POUR DES FLUIDES ACTIFS
Abstract
(EN)
The invention relates to a device for measuring the viscosity of a fluid, such as a rheometer (1), the device comprising two coaxial parts (11, 12), one of which is rotated relative to the other, which remains stationary, a receiving compartment (13) being provided between the two parts in order to accommodate a fluid to be examined. The invention is characterised in that at least one of the parts is made of a porous material.
(FR)
L'invention concerne un dispositif de mesure de la viscosité d'un fluide tel qu'un rhéomètre (1) comprenant deux pièces coaxiales (11, 12) dont l'une est entraînée rotation par rapport à l'autre qui reste fixe, un compartiment de réception (13) étant ménagé entre les deux pièces pour accueillir un fluide à étudier. L'invention consiste en ce qu'au moins l'une desdites pièces est réalisée en un matériau poreux.
