Abstract:
These papers describe the first set of experiment conducted to validate a measurement system for physical-chemistry analysis of fluids using ultrasound as principle. Frequencies of 2.25, 3.00, and 3.50 MHz were used, with the emission-reception technique with a pair of transducers. Experimental results showed excellent agreement with the theory for attenuation of glycerol at 99.5% of concentration. The system is able to be used in other liquids, being biofuels particularly of interest for this project.
