1. An apparatus, for measuring concentration, distribution and flow of solids suspended in a flowing liquid, which comprises:
a transmitter emitting at least one directional beam of an acoustical waveform;
at least one detector receiving echo signals of said waveform backscattered from said solids;
means for gathering measured intensity values of said echo signals;
means for measuring Doppler frequency shifts of said echo signals; and
data processing equipment comprising means for translating said intensity values into concentration values of said solids,
and means for interpreting said frequency shifts into flow measurements of said solids.
