What is an Auto Level?
An auto level or automatic level is a precision optical instrument used in surveying and building construction to establish a perfectly level line of sight to measure elevation differences. It is widely used in construction, civil engineering, road projects, land development and infrastructure jobs. It offers fast, reliable and accurate leveling.
The primary function of an auto level instrument is to determine the elevation difference between two or more points. These measurements are used by engineers to make sure that foundations, roads, drainage systems, pipelines and structures are built at the correct elevations.
The automatic level has an internal compensator that automatically compensates for minor tilts after rough leveling . Traditional dumpy levels do not have this . This removes the need for constant manual adjustment and greatly increases the speed and accuracy of surveys.
Auto level machine is one of the most reliable land surveying tools today. It is user friendly, durable and can be used by both the beginner and the experienced surveyor.
How Does an Automatic Level Work?
An automatic level is based on the principle of optical leveling with automatic compensating mechanism.
The instrument is first placed on a tripod and approximately leveled with the circular bubble. When the bubble is centered, the internal compensator takes over and automatically moves the telescope to keep the line of sight perfectly level.
A leveling staff is then placed at a variety of survey points. The surveyor peers through the telescope at the staff and records the readings. The readings are used to determine difference in elevation between known benchmarks and new points.
Because the compensator automatically keeps the line of sight horizontal, an auto level survey is much faster and more accurate than traditional manual leveling methods.

Auto Level We Offer
Main Components of an Auto Level Instrument
The modern auto level instrument is made up of several precision components that work together to give accurate survey results.
Telescope
Through the telescope you see a magnified view of the leveling staff. High quality optics that give sharp images and accurate readings at long distances.
Compensator (Inside)
The internal compensator is the main element of an automatic level. It has automatic self-levelling so the line of site remains horizontal during the survey.
Bubble Circular
At first, the round bubble is used to get the instrument approximately level, and then the compensator takes over.
Horizontal Circle
Many auto level machines have a horizontal circle that surveyors can use as a reference for approximate horizontal directions.
Screws Adjustment
The screws serve to centre the bubble during setup and help to ensure the instruments are correctly located.
Eyepiece
The crosshairs can be focused through the eyepiece for clear and accurate viewing.
Lens Objective
The objective lens collects the light and forms a bright and sharp image of the leveling staff, which improves the accuracy of the measurement.
Baseplate
The base plate secures the instrument firmly to the tripod and provides a stable base for surveying.

Applications of Auto Level in Civil Engineering
Auto levels are probably the most common survey instruments used in civil engineering since most construction projects require accurate elevation readings. An automatic level is essential for a small home or a large infrastructure project to make sure all structures are built to the design specifications.
Construction Building
Before building starts , engineers do an auto level survey to set benchmark levels and find out height of ground . Auto level instruments help keep floor levels, column heights and roof elevations consistent during construction, lowering the risk of structural errors.
Road and Highway Building
The construction of roads requires accurate gradients and cross-sections to provide adequate drainage and comfortable driving conditions. An auto level machine is used during construction to measure formation levels, pavement thickness and finished road elevations.
Construction of Bridge
Bridge projects are very precise. Surveyors use automatic levels to check foundation elevations, pier heights, deck levels and the position of expansion joints. Leveling properly guarantees the stability of the structure and the accuracy of the design.
Railway Projects
Railway tracks need to be correctly aligned and have uniform gradients. Engineers use auto level instruments to check the level of the track, the thickness of the ballast and the height of station platforms to ensure safe railway operations.
Canal Building and Irrigation
Water flow depends on the right slopes. Auto level Survey is used in irrigation projects to ensure canals, pipelines, drainage systems have proper gradient for smooth flow of water.
Land Development
Surveyors use an auto level machine to find the present ground levels and calculate how much cutting and filling is needed before any residential or commercial development takes place.
Industrial Projects
Factories, warehouses, airports, power plants – all require very accurate leveling when being built. An automatic level helps engineers keep floors flat and equipment installed correctly.
Auto Level Survey Process (Step-by-Step)
An auto level survey is a very simple survey but the correct procedures should be followed so as to obtain accurate results.
Step 1 – Choose the Location of the Survey
Pick a firm location with a clear view of all survey points. Be careful of soft ground that can make the tripod move.
Step 2 – Assembling the tripod
Open the tripod legs wide and push them firmly into the ground. The tripod should be stable during the survey.
Step 3 – Connect the Auto Level Instrument
Use the mounting screw to attach the auto level instrument to the tripod. Before any adjustments are made, ensure that it is well secured.
Step 4 – Rough Leveling of the Instrument.
Use the circular bubble and leveling screws to level the bubble. This is just a first change.
Step 5 – Internal Compensation
Once the rough leveling has been completed, the built-in compensator automatically creates a perfectly horizontal line of sight.
Step 6 – Position the Telescope
Adjust the eyepiece and focusing knob until the crosshairs and leveling staff are both in focus and clear.
Step 7 – Read the Backsight Reading
Set the leveling staff on the benchmark and note the backsight reading.
Step 8 – Readings in Between
Carry the staff to the different survey points and note down all the readings correctly.
Step 9 – Do the Foresight Reading
Record the last reading of foresight before you move the instrument to a second setup position.
Step 10 – Calculating Elevations
Using the recorded readings determine the Reduced Levels (RL), height differences and benchmark elevations.
This process ensures that all auto level survey work will produce accurate and repeatable results.

Auto Level FAQ
An auto level (or automatic level) is a surveying instrument used to establish or check points in the same horizontal plane. It is used extensively in construction, land surveying, foundation work and road projects to ensure accurate leveling.
The cost of auto-level machines depends on the model, magnification, and accuracy. The Topcon auto level price for the ATB series varies for different tiers based on the project requirement. Get in touch with Skipper Technologies for the recent price list on auto levels and a customized quote.
The auto level is often used for height difference and leveling. A total station is a more sophisticated instrument for measuring distances and angles for full 3D surveying. Auto levels are simpler to use and cheaper and are good for simple leveling jobs.
Depends on how big your project is, and how accurate you need to be. ATB 2 is ideal for small and medium construction sites. ATB 3A is ideal for general surveying and civil engineering. ATB 4A is ideal for precision on large infrastructure projects.
Topcon automatic levels use an internal compensator to keep the line of sight perfectly level . Usually accurate enough for construction, foundation layout and general land surveying work.
