A7.3 - Ultrasonic Sensor for Viscosity of Mineral Oil for Built-in Pipe Applications

B. R. Tittmann, H. S. Ju & E. J. Gottlieb
Ultrasonic methods have been developed to measure the viscosity elastic properties using the shear reflectance, and the mode conversion of the shear waves has been utilized for vegetable oil viscosity measurement by the relation between the shear properties and ultrasonic wave propagation. These methods have been restricted in pipeline applications, because for the protection from harsh fluid conditions such as high temperature and corrosion, ultrasonic transducers can be equipped with steel housings which restrict the...
