Chemical Technology, Control and Management


The model developed electromagnetic flow sensors with ring channels and alternating magnetic poles alternately in a three-dimensional approximation and the results of a study of their static characteristics. It was shown that due to the formation in the pipeline system with alternating magnetic poles is substantially increased channel length of the active zone of the sensor, thereby improving sensitivity of measurement. Found that the positive effect, i.e. fuller use of the cross-sectional area of the pipeline in the area of the electrodes is especially pronounced in the flow sensor with a diameter of 150 mm pipeline. It was found that the developed electromagnetic flow sensors allow to produce records of undistorted streams of water with an accuracy better than ± 0,5%.
