<p>The system has a detector unit (10), which is formed in a shape of a scraper, so that the detector unit is movable within a fluid conduit (12) relative to the inner circumferential surface (20), where a reference axis (18) of the detector unit is defined. The detector unit performs with a sensor device (36), by which the distance between the inner circumferential surface of the fluid conduit and the reference axis is detected in one or more directions radial to the reference axis. The sensor device has a tactile pressure sensor (44), which cooperates with the inner circumferential surface.</p> |
