Flow measuring Device for Nuclear magnetic resonance and Method for operating a device of measuring Flow by nuclear Magnetic Resonance

摘要

An NMR flow measuring device (1) is described and represented to determine the flow of fluid through the measuring tube (2) of the invention,There is a magnetic field generator (3) composed of permanent magnet, which generates a magnetic field, passes through the measuring tube (2), LM in a magnetic field section, and there is a front magnetic field section of LVM in the magnetic field section, In addition, a measuring device is also installed in the M magnetic field part, which includes a coil (5) antenna with a length of l832121 as the measuring antenna.LVM has at least one coil antenna (5) that generates a pulse to destroy the magnetization of the fluid to the magnetic field, or a pulse sequence to destroy the magnetization of the fluid to the magnetic field.
