Measuring system (2) intended for determining an alignment, comprising a fastening arrangement (4) and a measuring means (6). The fastening arrangement (4) comprises an elongate non-elastic fitting element (8) with a predetermined length 2L, which has a marking C at length L. The fastening arrangement (4) has two ends (10) each provided with a fastening device (12) which is adapted to fastening the fastening arrangement (4) to a planar surface (14). The measuring means (6) is elongate and non-elastic, has a length 2d greater than 2L and is adapted to having its ends (16) fastened to the fastening arrangement (4) at two fastening points (18) at the end-points of the predetermined length 2L. The measuring means (6) has at least one measurement marking (M1 ) which is placed at the position for d, at the time of measurement the fastening devices (12) are fitted on a planar surface (14) in such a way that the marking C on the fitting element (8) corresponds to a given position, the measuring means (6) is fastened to the fastening arrangement (4) and protrudes, and the position sought corresponds to the position of the measurement marking M1. |
