ABSTRACT:
A method of measuring characteristics of a flowing fluid is described including: (a) providing a flowing fluid; (b) applying a static field gradient to the flowing fluid; (c) applying a series of nuclear magnetic resonance pulses to the flowing fluid; (d) detecting signals from the flowing fluid, wherein the signals are generated in response to the nuclear magnetic resonance pulses; and (e) analyzing the real and imaginary components of the signals to determine one or more characteristics of the flowing fluid. Also described is an apparatus for implementing this method.
