level rod [′lev·əl ‚räd]

(engineering)

A straight rod or bar, with a flat face graduated in plainly visible linear units with zero at the bottom, used in measuring the vertical distance between a point of the earth's surface and the line of sight of a leveling instrument that has been adjusted to the horizontal position.

Level Rod

a measuring device used in leveling; it is a wooden stick 3–4 m long with a rectangular or I-shaped cross section and a scale inscribed on its face. A distinction is made between checkered and lined rods.

On one or both sides of a checkered rod there are white and black or red and white checkers 1 cm wide; divisions are marked at each decimeter, and the zero lines on the scales on both sides are offset a given distance relative to one another (Figure 1, a; BC is the plumb bob). Lined rods are used for highprecision

leveling. The front side has a channel in which an invar strip with two rows of lines 1 mm thick and 5 mm apart is stretched with a force of approximately 200 newtons (20 kilograms-force). There are divisions marked every half decimeter (Figure 1, b).
