Apparatus for the production of magnetic fields for polarizing and inducing resonance in a flowing medium |
摘要 |
Apparatus for the measurement of mass throughput in a flowing medium comprises a conduit between the pole pieces of an electromagnet which produces polarizing and resonating fields. The pole pieces are shaped to provide a first section in which the separation of the pieces is relatively small and a second, shorter section in which the separation is greater. The single magnet thereby produces different flux densities for polarizing and inducing nuclear resonance respectively and an improved signal-to-noise ratio by the application of a polarizing field which is more intense than the resonating field.
