The Sonic Doppler shift principle is investigated for the measurement of high concentration coal slurries (5 to 40% solid). A noninvasive system having a transducer on the outside of the pipe is especially attractive for safety and convenience in operation and maintenance. The ideal single frequency scattered energy is not realized in practice but a broad band of scattered energy is observed. The spectrum has a definite maximum value close to the expected Doppler frequency. A single number output can be obtained by amplitude limiting the difference frequency between transmitted and received signal and counting zero crossings.
