“…The magnitude of the reflection coefficient are related to changes in the amplitude of the signals. The methods of measuring viscosity by amplitude variation are called amplitude method, which including the multiple reflection (MR) method, central frequency (CF) method, and IR in a frequency band method (Franco, Adamowski, & Buiochi, ; Franco & Buiochi, ). MR method works in time domain, CF and IR both work in frequency domain.…”

“…Ultrasonic testing (UT) provides some technologies for online process monitoring, such as evaluating the aging of a structure (Voigt, ), determining the viscoelastic behavior (Gasparoux, Laux, Ferrandis, Attal, & Tordjeman, ; Lionetto & Maffezzoli, ; Voigt, ) and polymer curing (Dixon & Lanyon, ). The most remarkable property of UT is that it can achieve real‐time and on‐site detection (Franco & Buiochi, ). It is not limited to static and dynamic liquids, because the sensor has a solid surface that can be couple to a container wall (Moore & McSkimin, ; Shah & Balasubramaniam, ).…”

“…Recently, modeling similar responses using silicone oil (Zhai, Su, & Cai, ) and cooking oil (Alouache, Laux, Hamitouche, Bacharic, & Boutkedjirta, ; Franco, Adamowski, & Buiochi, ) have been tried. Franco and Buiochi () developed two methods for data post‐processing to reduce the errors caused by oscillating behavior in a single frequency.…”

“…In this work, the shear‐wave reflectometry method was employed for the viscosity measurement of peanut oil and rapeseed oil samples at 25 ± 0.2°C. To improve the accuracy of the measurements done by reflectometry, one can work with integral ratio (IR) in a frequency band instead of a single frequency, as it was done by Franco and Buiochi (). At the same time, the experimental parameters were optimized by theoretical analysis.…”

“…The amplitude of the reflection coefficient is relatively easy to measure. Substitute Equation (4) in (2) and the dynamic viscosity of Newtonian fluids only related to r is (Franco & Buiochi, ):

η = \frac{2 {Z_{normals}}^{2}}{{italicωρ}_{normalL}} {[\frac{1 - r^{2}}{1 + r^{2} + {[r^{2} (6 - r^{2}) - 1]}^{1 / 2}}]}^{2}

Effects of frying cycles of two types of edible oil on dynamic viscosity were studied by ultrasonic shear-wave reflectance method. Factors affecting the reflection coefficient were analyzed theoretically. The experimental methods and parameters are carefully analyzed and optimized in the low-viscosity case. The viscosity of the reheated oil samples was characterized by the reflection amplitudes at (25 ± 0.2) .Three methodologies for data post-processing were used to calculate the reflection
