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.
