Abstract

Dispositif de mesure du débit volumique d'un liquide dans un tronçon de tube isolant muni de deux electrodes diamétralement opposées, un champ magnétique étant perpendiculaire à la droite reliant les électrodes et à l'axe du tube. La composante By du champ Bx, By, Bz, à partir d'un point minimum xs, ys, zs situé à une distance de l'origine qui, suivant l'axe des y, est inférieure à 0,45 fois et, suivant les axes des x et des z, est inférieure à 0,1 fois le diamètre D du tube, décroît, selon l'axe des x, dans les deux sens jusqu'à la surface intérieure du tube, et, selon l'axe des z, croît dans les deux sens, puis décroît après un maximum. Application : mesure de débit de liquides dans un tubeDevice for measuring the volume flow rate of a liquid in a section of insulating tube provided with two diametrically opposed electrodes, a magnetic field being perpendicular to the line connecting the electrodes and to the axis of the tube. The By component of the Bx, By, Bz field, from a minimum point xs, ys, zs located at a distance from the origin which, along the y axis, is less than 0.45 times and, following the x and z axes, is less than 0.1 times the diameter D of the tube, decreases, along the x axis, in both directions to the inner surface of the tube, and, along the axis of z, increases in both directions, then decreases after a maximum. Application: flow measurement of liquids in a tube
