ACOUSTIC FLOWMETER WITH REYNOLDS NUMBER COMPENSATION

摘要

13 48,400ABSTRACT OF THE DISCLOSUREAn acoustic flowmeter wherein pulses of acousticenergy are transmitted between upstream and downstreamtransducers through the fluid under measurement and where-in the arithmetic computation of velocity based upon thedifference in time measurement of the oppositely-directedpulses is modified by predetermined factors to automatic-ally compensate for errors caused by a Reynolds numberchange due to flow velocity change.
