Density is one of the most widely used composition-based measurements in industrial process control. However, it is well recognized that the presence of small, but unknown levels of entrained gases can mask the density of the non-aerated component of a process mixture, resulting in an inaccurate determination of process fluid density. Recently, SONAR-based, clamp-on gas volume fraction meters have been introduced which provide an accurate, real time, measurement of entrained gases.
