We describe an NMR method to make a quick determination of average fluid velocity by monitoring the change in phase of the magnetization during a transient signal. We give an example utilizing the second Cam-Purcell-Meiboom-Gill echo in which we measured the velocity of water up to 54 cm/s where eac
