Method and device for measuring the volume fraction of one or other of the phases of a two-phase mixture

摘要

The invention relates to a method for measuring the volume fraction of one of the phases of a two-phase mixture. / p & & p & this process is characterizes in that, after having beforehand determine the speed of propagation of an ultrasonic signal in the phase φ and the speed of propagation of an ultrasonic signal in the stage f, a signal emet ultra / p & & p & a measurement of the degree of retention of the phase scattered in a column of the extraction liquid -.
