ABSTRACT:
A method and apparatus for fluid mixture monitoring and controlling using an acoustic sensing technique by pulsing a fluid sample and a reference fluid in elongated chambers with sound waves generated at one end of the chambers and sensing the resonant frequencies in the chambers, or the time lapse for the sound waves to traverse the chambers, with transducers disposed proximate the other ends of the chambers and ratiometrically comparing the time-based measurements.
