<p>A level indicator has a holder (3) that rotates around a first axis (6) and supports a distance measurer (5) that rotates around a second axis (7). A motor (34) drives the holder (3), a motor drive (135) drives the distance measurer (5), a shaft encoder (35) has an axis (8) linked by a transmission to the axis (9) of the motor (34) that drives the holder (3), and a computer (C) is provided with a program for evaluating the signals supplied by the distance measurer (5) and by the shaft encoder (35) according to signals generated by the computer itself for controlling the motor drive (135).</p> |
