Ultrasonic impulse method for measuring physical characteristics of fluid, involves producing traversal or longitudinal oscillation in solid body, placed in acoustic contact with tested fluid, and acoustic fluid characteristics are measured

摘要

The ultrasonic impulse method involves producing a traversal or longitudinal oscillation in a solid body, placed in an acoustic contact with a tested fluid. Acoustic fluid characteristics are measured during measuring amplitudes of an acoustic signal in the solid body. Measured parameters include density and viscosity of the tested fluid. A measuring geometry is selected for producing and receiving the ultrasound and a geometrical form of the solid body. A surface area of a solid surface in the acoustic contact is m times greater than the surface area of an ultrasonic bunch cross section. An independent claim is also included for a device for realizing a method for measuring a physical characteristic of a fluid.
