ABSTRACT:
A method and apparatus for determining fluid motion of a fluid through a conduit whereby the signal pulse repetition frequency of a pulsed Doppler is increased significantly over known systems and the receiving means for the reflected signals is kept activated for essentially the entire time that the transmitting means is inactive so that a Doppler shift of less than one-half the signal repetition frequency is produced and frequency aliasing is avoided. The same transducer can be utilized to transmit and receive signals and detect high Doppler shifts, thus functioning similarly to continuous wave Doppler systems using separate transmit and receive transducers.
