Viscosimeter with a funnel and capillary, for measuring the viscosity of industrial fluids, in particular in the oil industry

摘要

The invention relates to a viscosimeter constituted of a funnel 7, 8 connected at its lower part to a capillary tube 9 in which the fluid flows with a Hagen-Poiseuille type flow. For non-Newtonian fluids, the apparatus is made to operate in emptying mode, the flow rate is measured and at least part of the rheogram is thus easily and quickly obtained. IMAGE
