Stepping motor driven constant-shear-rate rotating viscometer
(2004-10-08)
Despite the frequent use of stepping motors in robotics, automation and in a variety of precision instruments, they can hardly be found in rotational viscometers. This paper proposes the use of a stepping motor to drive ...

P3L-3 Viscosity measurement of Newtonian liquids using the complex reflection coefficient
(2006-12-01)
This work presents the implementation of the ultrasonic shear reflectance method for viscosity measurement of Newtonian liquids using wave mode conversion from longitudinal to shear waves and vice-versa. The method is based ...
Theoretical Analysis of the Gravity Driven Capillary Viscometers
(American Institute of Physics, 2004-03)
Gravity-driven capillary viscometers (GDCVs) are used to obtain the viscosity function of non-Newtonian fluids from measurements of the instantaneous fluid height in the overhead reservoir. The reliability of this viscometry ...

Misturador para análise de propriedades reológicas
(2010)
This study aimed to evaluate the use of a mixer to determine the rheological properties of fluids. The mixer is comprised of an agitation tank and an anchor type impeller. The tests were performed with honey and fruit ...
