发明名称 DEVICE FOR MEASURING COMPOSITION AND FLOW OF MULTI-COMPONENT LIQUID ON BASIS OF NUCLEAR MAGNETIC RESONANCE (VARIANTS)
摘要 FIELD: physics. ^ SUBSTANCE: device has magnetic system, pipe, made of non-magnetic material, portion of which is placed in magnetic field between end pieces of magnetic system, radio-frequency coil, electronic signals processing block, pressure sensor and temperature sensor, while portion of pipe which is positioned in magnetic field between poles of magnetic system, made with such a diameter, where conditions for realization of nuclear magnetic resonance are realized, i.e. relative change of magnetic induction in any direction within that volume does not exceed 10-3, radio-frequency coil, positioned between Faraday screens and connected to electronic signals processing block, is positioned coaxially inside central pipe portion in such a way that axes of inter-polar space of magnetic system and radiofrequency coil were positioned perpendicularly to each other, while center of coil constructively is positioned in the center of inter-polar space of magnetic system. ^ EFFECT: higher precision, higher efficiency, simplified construction, lesser dimensions and weight. ^ 4 cl, 9 dwg
