DEVICE OF THE NON-CONTACT MAGNETOMETRIC CONTROL OVER THE STATE OF THE PIPELINE METAL Russian patent published in 2007 - IPC G01N27/72 

FIELD: oil-producing industry; natural gas industry; production of the devices of the non-tactless magnetometric control over the state of the pipeline metal.

SUBSTANCE: the invention is pertaining to the oil-producing industry and the natural gas industry and may be used for control over the state of the pipeline metal. The technical result of the invention is the increased efficiency, operability and accuracy of the measurements. The device contains two blocks of the flux-gate magnetometers with three flux-gate sensors rigidly connected among themselves, the block of electronic switches, the indicating device, the control unit, the block of determination of the position, on which the first and second blocks of the flux-gate magnetometers are rigidly set, the block of the control and the data processing, the inductive sensors of the magnetic field. The inductive sensors are rigidly connected among themselves and are installed along a straight line being the prolongation of the radius of the pipeline duct. The shafts of sensitivity of the inductive sensors are in parallel to each other and are oppositely directed, arranged in the plane perpendicular to the pipeline, and are collinear to the rigidly connected to each other shafts of sensitivity of the second flux-gate sensors of each block of the magnetometers.

EFFECT: the invention ensures the increased efficiency, operability and accuracy of the measurements.
