A system and method for detecting the passage of the pipeline inner object, a non-destructive sensing device having a microcontroller, having one or more shielded magnetometer sensor and an adjustable threshold detector. The adjustable threshold device means are thus the data stream to remove outliers and outliers removed from the data stream, the magnetic flux passing through the four low-pass filter. Made smooth amplitude of the data stream, it is compared with the detection limit, when the passing event last detected is displayed, and increasing the counter in the display device, and travel time is recorded, two statistics are displayed on the display device. Because it might be a single object to form a plurality of magnetic field detectors come locked for the duration of the predetermined time after the passing event, to prevent the secondary detection of the object is about to be passed through a sensing apparatus, the same object.
