Results of multipurpose studies aimed at the development of advanced instrumentation for ultrasonic diagnos
tics of liquid media are reported. It has been inferred that, for the near decades, the most promising route will
be combined (medium-interactive) ultrasonic devices based on waveguides of different design. Diagnostics
data on argillaceous rocks and technical ceramics are given.
Under modern conditions, the technological, economic
and environmental problems and the human safety consider
ations both at factory and at home have become the most de
manding challenge ever met. Viewed in this light, engineer-
ing diagnostics (nondestructive testing, in particular, ultra-
sonic testing) of different media (aggressive, explosive, ra-
dioactive etc.) has been gaining in importance on a national
The ultrasonic diagnostics of various fluids and gases has
been gaining an ever-expanding practical application since it
provides a means of controlling the parameters (density, con
centration, temperatures, etc.) of aggressive media and mate-
rials exposed to high temperature, high pressure and ionizing
radiation. Thus, the ultrasonic method has found use in the
liquid level control in experimental reactors at nuclear power
Still, as practice has shown, the conventional ultrasonic
testing techniques, currently in use in industry and power en-
gineering, may fail to provide the required accuracy and reli-
ability of measurement, in particular, of fluid processing me-
