NUCLEAR MAGNETIC FLOWMETER AND METHOD FOR OPERATING NUCLEAR MAGNETIC FLOWMETERS Russian patent published in 2018 - IPC G01F1/56 G01F1/58 G01F1/74 G01N24/08 G01R33/563 

FIELD: meter reading.

SUBSTANCE: invention relates to nuclear magnetic flowmeter (1) for determining the flow rate of a medium flowing through measuring tube (2), having magnetic field generation device (4), measuring device (5) and antenna device (6) with antenna (7). Magnetic field generation device (4) permeates flowing medium (3) with a magnetic field having at least one component perpendicular to longitudinal axis (8) of the measuring tube via magnetic field section (9) oriented parallel to longitudinal axis (8) of the measuring tube in order to magnetise medium (3), wherein measuring device (5) is designed to generate excitation signals which excite magnetised medium (3) and to measure the measurement signals caused by the excitation signals in magnetised medium (3), and wherein antenna (7) is in the form of a coil and is designed to transmit the excitation signals to magnetised medium (3) via measurement section (10) which is oriented parallel to longitudinal axis (8) of the measuring tube and is in magnetic field section (9) and to detect the measurement signals. Antenna device (6) has at least one further antenna (11, 12), said further antenna (11, 12) is in the form of a coil and is designed to transmit the excitation signals to magnetised medium (3) via a further measurement section (13, 14) which is oriented parallel to longitudinal axis (8) of the measuring tube and is in magnetic field section (9) and to detect the measurement signals, and measurement section (10) and further measurement section (13, 14) are different.

EFFECT: technical result is the creation of a nuclear magnetic flowmeter that has improved reliability.
