ABSTRACT:
A process and device for measuring and processing in real time the changes of level between two or more points in buildings, structures, machinery or the like, when interested by works of civil engineering, wherein a laser ray generated by a laser tube and rotated on a planar or conical surface hits one or more targets constituted by fixed or mobile photodetectors, said targets being placed in correspondence with said points. The signals generated by the targets are transferred to a computer to be processed and immediately read (FIG. 1).
