| Summary: | Real-time process monitoring is important in many areas of
industry and scienti c research concerning liquid/gas
two-phase ow, and is closely related to accurate measurement
and control of hydrodynamic parameters such as ow
regime and ow rate. Ultrasonic tomography has the
advantage of imaging two component ows by providing
quantitative and real-time data on media, without process
interruption. It allows insight of the process, enables
closed-loop control systems and is noninvasive and possibly
non-intrusive. The overall anticipated e ects are improvements
in product yield and uniformity, minimized input
process material, reduced energy consumption and
environmental impact, and lowering exposure to plant
personnel. Ultrasonic tomography enables the measurement
of certain characteristics of objects that cannot be
easily obtained by other methods. Ultrasounds are able to
detect changes in acoustic impedance which is closely
related to the media density and complements other
tomographic imaging technologies. |
