Energy method to calculate the density of liquids using ultrasonic reflection techniques
(2001-12-01)
In this work it is introduced a new approach to calculate the density of liquids in terms of the energies of the acoustic signals. This method is compared to other methods in the time domain (peak-to-peak amplitudes) and ...

Ultrasonic measurement of viscosity: Signal processing methodologies
(Universidad Autónoma de Occidente, 2019-01)
This work deals with two alternative methodologies for data post-processing resulting from the ultrasonic shear-wave reflectance method used for liquid viscosity measurement. In the shear-wave reflectance method, the ...
Experimental study of the complex reflection coefficient of shear waves from the solid-liquid interface
(2010-01-01)
The determination of the reflection coefficient of shear waves reflected from a solid-liquid interface is an important method in order to study the viscoelastic properties of liquids at high frequency. The reflection ...
Shear-wave corner retroreflector device for ultrasonic measurement of viscosity
(Revista Ultrasonics, 2021)
This work shows a novel ultrasonic viscosity measurement device with increased sensitivity. The measuring
principle is based on the determination of the complex reflection coefficient of shear-waves at the solid–liquid
