Level Instrument

An optical or digital instrument that provides a precise horizontal line of sight for measuring height differences.

A level instrument is a geodetic instrument designed for precise determination of height differences between points. It provides a horizontal line of sight, allowing height differences to be determined with millimeter precision.

Types of level instruments:

  • Optical levels - classic type with optical sighting system
  • Digital levels - automatic rod reading with high precision
  • Laser levels - projects horizontal or vertical laser line
  • Automatic levels - with compensator for automatic leveling

Level precision:

  • Precise levels - ±0.3 mm per km (national network measurements)
  • Technical levels - ±2-3 mm per km (engineering work)
  • Construction levels - ±5-10 mm per km (construction site work)

Leveling equipment:

  • Level - instrument with horizontal sight
  • Leveling rod - graduated scale with millimeter divisions
  • Tripod - stable support for instrument
  • Measuring rod - additional measuring tool

When is a level used?

  • Height measurement - precise height transfer
  • Construction - foundation, floor, road height control
  • Drainage - ditch and drainage system design
  • Deformation monitoring - building settlement measurement
  • Industrial measurements - equipment horizontality check

Digital level advantages:

  • Automatic reading registration
  • No human reading error
  • Faster work execution
  • Automatic data processing
  • Electronic documentation

The level remains an essential part of surveying instrument kit, providing the highest precision in height determination.
