ABSTRACT:
The fractional volumetric holdup .phi. of a dispersed phase in a two liquid dispersed phase system in a reactor is determined by measuring the travel time of ultrasonic pulses on a fixed path for the dispersed phase, and for the two liquids separately, and calcualted according to the relation ##EQU1## where C*, C.sub.1, and C.sub.2 are the sound velocities in the dispersed phase, the first liquid, and the second liquid. The pulses can be transmitted from a transmitter transducer straight through the contents of the reactor to a receive transducer, or can be reflected off a die or similar flat faced member back to the originating transducer. A sonic velocimeter is disposed along the reactor and draws out a quantity of the two-liquid system, and separates it into the first and second liquids. The sound velocity of each liquid is measured with ultrasonic transducers, and the dispersed phase holdup .phi. is calculated based on these measured velocities. This technique compensates for changes in the sound velocities which accompany ongoing physical and chemical changes in the respective phases.
