FIELD: measuring engineering. ^ SUBSTANCE: system comprises three inductive pickups of magnetic field arranged in a plane perpendicular to the pipeline. The pickups are rigidly interconnected and arranged along the straight line which is an extension of the radius of the pipeline. The axes of the first and second (top and bottom) pickups are arranged in a plane orthogonal to the pipeline and perpendicular to the axis of the third pickup which is aligned with the radial strait line of the pipeline. The system also has indicator, switch of operation type, step controller of amplification, first selective amplifier, device for control and processing, keyboard, three preamplifiers, magnetometer, second selective amplifier, and amplifier. ^ EFFECT: enhanced accuracy of measuring. ^ 4 dwg |
