ABSTRACT:
An acoustic flowmeter wherein pulses of acoustic energy are transmitted between upstream and downstream transducers through the fluid under measurement and wherein the arithmetic computation of velocity based upon the difference in time measurement of the oppositely-directed pulses is modified by predetermined factors to automatically compensate for errors caused by a Reynolds number change due to flow velocity change.
