Auto Level

An auto level, also known as a builder's auto level, automatic level, or levelling instrument, isan optical instrument used in surveying and construction to establish or verify points in the same horizontal plane.It's crucial for measuring height differences, transferring heights, and setting heights in various projects.

Functionality:

• Horizontal Plane:

Auto levels create a horizontal reference plane, allowing for accurate height measurements and transfer.

• Height Measurement:

They are used with a levelling staff to determine the height differences between points.

• Applications:

Commonly used in construction, road building, and other projects where precise height measurements are essential for stability and accuracy.

• Internal Compensator:

An internal compensator mechanism ensures the line of sight remains horizontal even if the instrument isn't perfectly level.

How it works:

1. Setup:

The auto level is mounted on a tripod, and the operator roughly levels the instrument using the levelling screws.

2. Height of Collimation:

The instrument's internal compensator automatically adjusts the line of sight to a horizontal plane.The height of this plane is then determined by sighting a levelling staff on a known benchmark or an arbitrary point.

3. Measurements:

By sighting the staff at different points and recording the readings, the height differences between those points can be calculated.

Key Features:

• Optical Instrument:

Auto levels use optics to create a precise line of sight for accurate measurements.

• Durability:

They are designed to withstand various environmental conditions on construction sites.

• Ease of Use:
