Guide to Best Digital Levels for Land Surveying in 2021

Engineers Surveying Land

 

It has never been easier to determine the height or height difference between points than with the advent of digital leveling systems. For land surveyors and construction professionals, a digital level produces an accurate reading of graduated marks on a leveling rod. Save time, money, and headaches all while storing a large amount of data without having to write it down.

What Is a Digital Level?

A digital level is a standard tool used in land surveying projects. Land surveyors use them to perform advanced and automatic height calculations on the job site. Measure the height difference between two points, measure an angle or slope, keep your structure level and plumb, and determine the height of a structure.

Digital levels can perform a variety of fast and automatic calculations including calculating:

  • Pitch
  • Angles/inclination
  • Vertical lines

Digital levels include a magnifying lens and telescope which varies by model. They are mounted on top of a tripod base, which can rotate 360 degrees for measuring the entire span of your land. Capture angles and determine level and slope positions, as well as different calculations in the vast internal memory remotely.

How Does a Digital Level Work?

Digital levels are easy to use on the job site. Simply set up the tripod and mount the level with the tripod screw. Stand behind the device, and level the level with the bubble level by looking down through the bubble mirror. An automatic compensator with magnetic damping capabilities automatically maintains a level line of sight.

Press the power button, aim the staff, adjust the focus, and with the press of a button measure height and distance. The level shines a beam evenly over the length of the staff and reads the barcode from the graduated rod, thereby, completely reducing the risk of human error. Barcode measurements are automatically visible and stored on the device.

Digital levels make it easy to interpret the readings through LCD readouts. In addition, some advanced digital levels can emit an audible note when level and plumb or when the battery is running low.

These devices can provide precision under all conditions. Whether it is dimly-lit or the staff surface is partially shaded, these electronic devices can help land surveyors cut down on measuring time.

Factors to Consider When Choosing a Digital Level

When choosing the right level for you, there are many factors to consider. Generally, digital levels are accurate, easy to use, and rugged enough to handle the demands of the worksite. Here are a few factors to consider when investing in a hi-tech electronic level.

  • Accuracy: High-quality digital levels provide next-level accuracy.However, accuracy varies by model. How accurate do you want your readings? Will a difference of a few tenths of a millimeter make a difference.Accuracy can also vary depending on the leveling rod.
  • Measuring Range: How close and far can the level measure? Electronic measuring ranges tend to fall between 1.5 m and 100 m with some variations.
  • Storage: How big is your project? Levels can store a couple thousand reference points or up to 30,000. USB and SD card compatibility allows surveyors to transfer data. Just remember to back your data up regularly to prevent data loss.
  • Digital display; All levels feature a backlit LCD screen on the side and the top to easily read measurements even under low light conditions. Digital displays can include the staff reading, the horizontal distance to staff, and the remaining battery power.
  • Battery life: Levels are powered by single-use alkaline or rechargeable batteries. Consider the battery life of your device’s batteries after continuous use. Levels can last a couple of shifts to nearly cover the entire workweek without needing a charge. The best digital levels include an audible tone that signals a low battery.

What Is the Best Digital Level?

Whether you are measuring the slope of a pipe or wheelchair ramp, electronic digital levels ensure every installation is level and plumb. Each type of level has different features and varies in price, function, durability, accuracy, speed, among many other factors.

Sokkia

Sokkia is a leader in digital leveling products for the construction and land surveying industry. At an affordable price, Sookia’s line of electronic levels can provide a height difference and distance measurement in under 3 seconds.

  • Sokkia SDL30 Digital Level 32x: The SDL30 makes measuring quick and easy. Its innovative “wave-and-read” technology reduces measurement error when the staff is not vertical or does not have a bubble scope. The tool features 8.5 hours of continuous operation, a 2000 point internal memory, 4 measurement modes, and a 2-year warranty.
  • Sokkia SDL50 Digital Level 28x: Including many of the same features as the SDL30, the SDL50 differs in accuracy. SDL30: 0.4 mm (super-invar staff)/0.6 mm (Invar)/1.0 (fiberglass); SDL50: 0.6 mm (super-invar staff)/0.8 mm (invar)/1.5 mm (fiberglass).
  • Sokkia SDL1X Advanced Digital Level: The SDL1X features intelligent auto focus and wireless operation to produce the most accurate and productive readings. The electronic level can reduce measurement by up to 40% compared to a manual electronic level. A wireless remote trigger completely eliminates any measurement errors caused by touching. Features include 0.2 mm precision, 1.6-100 m range, 2.5 second measuring time, and 9 hours of battery life.

Digital Level Accessories

A complete level system includes more than me level itself. From its lithium battery to its case to its data transfer cable, every product can help you make accurate readings and store them for future reference. Invest in these digital angle finding tools to complete your leveling system.

  • Tripod: Stabilize your level on job sites of any terrain with a tripod for more accurate readings.
  • Leveling rod: Compatible leveling rods can be made out of aluminum or fiberglass construction for the most durability, balance, and safety.
  • Leveling plates: Leveling plates can improve the accuracy of readings when working in soft terrain.
  • Eye piece: Compatible eyepieces can improve the magnification of levels without having to invest in another model.
  • USB and transfer cable: Invest in a rugged USB stick, preferably in metal housing meant to withstand extreme environments and electrostatic charges. Look for power loss protection and other data retention features to protect you from data loss.
