This paper describes two ultrasonic flowmeters that employ the active cross-correlation technique and use a simple clamp-on transducer arrangement. The flowmeter for solid/liquid flows was tested over a wide range of coal concentrations in water and oil. The measured velocity based on the peak position of the cross-correlation function is consistently higher by about 15% than the average velocity measured by flow diversion. The origin of the difference results mainly from the flow velocity profiles and transit time probability distribution. The flowmeter that can measure particle velocity in a solid/gas flow requires an acoustic decoupling arrangement between two sensing stations. The measured velocity is mainly associated with the particles near the wall. Performance is described for both flowmeters. 13 references, 9 figures, 2 tables.
