APPARATUS AND METHOD FOR MEASURING VISCOSITY OF A FLUID

摘要

An apparatus and method are provided for measuring the viscosity of a fluid. The apparatus typically includes an inlet line that is configured to receive a flow of the fluid, and at least one porous medium column that receives the flow of the fluid from the inlet line and resists the flow so that a pressure of the fluid at the outlet is less than a pressure of the fluid at the inlet. A pressure sensor is configured to measure a pressure differential between an inlet and outlet of the column, and the sensor is adapted to determine the viscosity of the fluid according to the pressure differential and the permeability of the porous medium.
