We have developed an on-line computer-controlled sensor, based on ultrasound reflection
measurements, to determine the product of the viscosity and density of a liquid or slurry for …

An on-line sensor to measure the density of a liquid or slurry, based on longitudinal wave
reflection at the solid–fluid interface, has been developed by the staff at Pacific Northwest …

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 …

The effect of the viscosity of a fluid on the propagation of the zero mode of a horizontally
polarized normal wave in a thin (compared to the wavelength) waveguide immersed in the …

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 …

An on-line ultrasonic density sensor is described in which six transducers are mounted upon
a plastic wedge, the base of the wedge being in contact with a liquid or slurry. Ultrasonic …

Real-time viscosity measurement remains a necessity for highly automated industry. To
resolve this problem, many studies have been carried out using an ultrasonic shear wave …

Consequently, to find the impedance components R and X it is necessary to know the
thickness I and density Pl of the quartz plate and to determine experimentally the variation of …

There have been extensive demands from industries to determine information about the
contents inside pipelines and it would be a great benefit if on-line measurements could be …
