The detection of phenomena occurring inside multiphase opaque reactors is difficult. The present work investigated the novel application of a non-intrusive ultrasound monitoring technique to the complex case of gas–solid fluidized beds. Comparisons of data obtained from video-imaging and theoretical calculations with the ultrasound signal data demonstrate that the ultrasound system is a reliable means of characterizing essential bubble properties by measuring the point bubble frequency, when applying a special protocol during signal treatment. Additional uses in different multiphase systems are further described.
