Abstract
A method for measuring the viscosity of any liquid gaseous or supercritical, optionally multiphase fluid, under extended conditions of pressure, temperature and chemical composition, the method is based on the application of a flow law of the fluid through a permeable medium, the permeability of which is known. A viscosimeter for carrying out this measurement method is also described.

1-17. (canceled)
A method for measuring the viscosity of a fluid, comprising the steps consisting in:
- passing the fluid through a permeable material;
- measuring the flow rate of the fluid by means of a flow meter;
- measuring the pressure difference of the fluid between the pressure upstream of the permeable material and the pressure downstream of the permeable material;
- applying a flow law of the fluids through a permeable material in order to determine the viscosity of the fluid.
1 more element
A viscosimeter comprising:
- a cell comprising two chambers (11) and (12) separated by a permeable material (9), the first chamber (12) comprising an inlet opening (4) and the second chamber (11) comprising an outlet opening (5) for a fluid;
- a means for measuring the pressure difference between the first and second chambers;
- a flow meter for measuring the flow rate of the fluid.
