NMR FLOWMETER WITH SUPERCONDUCTING POLARIZER

摘要

A fluid flowmeter which uses nuclear magnetic resonance to determine quantities of flowing fluid(s) has a polarizing magnet system with magnets which are high temperature superconductors such as yttrium barium copper oxide (YBCO) or bismuth strontium calcium copper oxide (BSCCO) which are superconducting at liquid nitrogen temperature and provide a greater magnetic field strength than conventional magnets. This may allow the flowmeter to accept higher through flow rate and/or may allow observation of 23Na in an aqueous phase as well as 1H.
