Thermodynamic response of an ultrasonic densitometer
(2005-12-01)
An ultrasonic densitometer is experimentally characterized as a function of temperature. The measurement of propagation velocity and density of several liquids is performed in the 15 to 40°C temperature range. Results are ...
Ultrasonic material characterization using diffraction-free PVDF receivers
(2010-01-01)
This work describes the use of a large aperture PVDF receiver in the measurement of density of liquids and elastic constants of composite materials. The density measurement of several liquids is obtained with the accuracy ...
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 ...
Thermal characterization of an ultrasonic measurement cell
(2005-12-01)
Temperature plays an important role in any sensor device, because it can affect sensor properties, limiting its accuracy and operation range. At constant temperature, ultrasonic density sensors can reach accuracies of 0.1%. ...
