NMR methods for measuring fluid flow rates |
摘要 |
A method for measuring fluid flow rates comprises the steps of: (a) creating a non-oscillating magnetic field of a predetermined strength across a flowing fluid; (b) performing the sub-steps of: (i) exposing the flowing fluid to an oscillating magnetic field pulse orthogonal to the non-oscillating magnetic field to generate an NMR signal, and (ii) detecting the NMR signal from the flowing fluid in the form of a free induction decay; and (c) determining the fluid flow rate from the initial magnitude of the free induction decay.
