A solid corrosion-resistant torsional waveguide of diamond cross section has been developed to sense, online and in real-time, the characteristics of the liquid in which it is submerged. The sensor can measure, among other things, the liquid content of a bubbly medium, the density of adjacent pure liquids, the equivalent density of liquid-vapor mixtures or(More)
The following applications are reviewed: ultrasonic application data are summarized for these areas. Most of the measurements utilize approaches designed to respond primarily to sound speed, but some depend on attenuation effects. Most equip­ ment in use involves intrusive probes, but noninvasive, externally­ mounted A transducers are being promoted in(More)
