<p>Method and apparatus for the measurement of fluid flow velocities for instance in a slurry transport conduit (70), in which pulse signals are sent through the fluid by pairs of transmitting and receiving transducers (10, 11, 12, 13), said pulses having such time separation that standing waves caused by reflection die down within the time separation, and using side band techniques and correlation techniques.</p> |
