Ultrasonic characterization of emulsions: milk and water in oil
(1999-12-01)
Measurements of ultrasonic attenuation and velocity in milk and low concentration water-in-oil (W/O) emulsion were conducted, using a measurement cell with a double-element transducer that eliminates diffraction losses. ...

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%. ...
Thermal characterization of an ultrasonic density-measurement cell
(Institute of Electrical and Electronics Engineers (IEEE), 2007-06-01)
An ultrasonic density-measurement cell is experimentally characterized as a function of temperature. The measurement of propagation velocity and density of several liquids is performed in the 15 degrees C-40 degrees C ...

Ultrasonic density measurement cell design and simulation of non-ideal effects
(Elsevier B.V., 2006-07-01)
This paper presents a theoretical analysis of a density measurement cell using an unidimensional model composed by acoustic and electroacoustic transmission lines in order to simulate non-ideal effects. The model is ...
