Kipregel (from German Kippregel , from German kippen - to overturn (si) and fr. Règle - ruler ) - a mechanical or optical geodetic instrument designed to measure elevations, distances, vertical angles, graphically plot directions and apply them to the topographic plan of the landscape [ 1] . Kipregel is a part of the menzul set for topographic survey of the area  .
Kipregel usually includes:
- rack (column);
- telescope with rangefinder filament or sight ;
- vertical circle ( limb ) with degree divisions for determining the angle of inclination;
- a cylindrical level that is used for leveling (as a level );
- a scale ruler for displaying shooting points on a tablet.
Using a kipregel, shooting points are sighted, the distance to the point is determined by the range finder’s threads, the excess of the point is determined by the vertical angle and distance, and a line is drawn on the tablet to the point and the distance to it using a ruler.
At present, the menzul set, including the kipregel, is practically not used in topographic surveys, which are usually performed by theodolites and total stations .
