Sewer Pipe Deformation Measurement with the KS 135 Scan
Combine CCTV inspection with laser-based measurement of pipe diameter, deformation and profile deviations across the complete sewer reach.
The Rausch KS 135 Scan adds dimensional measurement to mainline CCTV inspection. Integrated laser technology scans the internal pipe profile as the crawler travels through the sewer, allowing changes in diameter and deformation to be measured and represented in detailed 2D and 3D visualisations.
Measure What CCTV Alone Cannot Quantify
A conventional CCTV survey shows the condition of the pipe. The KS 135 Scan adds dimensional information about the shape and internal profile of the sewer.
1
Pipe Diameter
Determine the internal diameter of the pipe using the integrated laser measurement system.
2
Deformation
Identify areas where the pipe profile has moved away from its expected circular shape.
3
Profile Deviations
Evaluate individual deviations at selected positions rather than relying only on a visual judgement from CCTV footage.
4
Complete Reach
Scan and analyse deformation along the complete measured sewer reach rather than taking isolated measurements alone.
Scan Process
Measure the Pipe During the Return Run
Once the CCTV inspection is complete, the KS 135 Scan can carry out the deformation measurement as the crawler returns through the pipe.
1
Position the Camera
The camera head is positioned perpendicular to the internal pipe wall.
2
Rotate the Laser
The camera rotates at a controlled speed while the integrated laser system scans the pipe profile.
3
Automatic Crawler Movement
The crawler travels through the reach under controlled movement while measurement data is recorded.
4
Calculate the Profile
The software continuously calculates pipe diameter, deviations and deformation along the measured reach.
Turn the Scan into Measurable Pipe Condition Data
Once the measurement run is complete, the software can immediately represent the measured pipe profile in both two and three dimensions.
Measurement Analysis
See Where the Pipe Has Changed Shape
The measured reach can be viewed as a three-dimensional pipe with deformation highlighted visually. Individual positions can then be selected to examine the measured cross-section and compare the pipe profile in more detail.

KS 135 Scan
CCTV Inspection and Measurement in One Camera System
The KS 135 Scan combines the functions of a mainline pan-and-tilt inspection camera with integrated laser measurement. The same crawler platform can therefore carry out the visual inspection and the subsequent deformation scan.

Is Deformation Measurement Right for Your Inspection?
Deformation measurement is most useful where a visual CCTV assessment needs to be supported by dimensional evidence about the internal shape of the pipe.
Choose Deformation Measurement
When You Need to Quantify the Pipe Profile
Use the KS 135 Scan where diameter, deflection or deformation needs to be measured across the sewer reach rather than estimated from CCTV footage alone.

Inspection & Reporting Only?
Explore PipeCommander
If your requirement is primarily recording CCTV observations, managing inspection projects and producing reports without full pipe-profile measurement, PipeCommander may be the more relevant solution.

Key information about pipe profiling, laser measurement, KS 135 Scan operation and 2D/3D analysis.
What is sewer pipe deformation measurement?
Sewer pipe deformation measurement is used to quantify changes in the internal shape of a pipe rather than relying only on visual assessment from CCTV footage.
The Rausch KS 135 Scan measures the internal pipe profile using integrated laser technology and can identify diameter changes and deformation along the measured reach.
How does the KS 135 Scan measure pipe deformation?
During the measurement run the camera is positioned toward the pipe wall and rotates while the crawler moves through the sewer.
The integrated laser measurement system provides the information used by the software to calculate the internal pipe profile, diameter and deviations.
Can deformation be measured along the complete sewer reach?
Yes. The scan function is designed to measure deformation across the complete measured reach rather than only checking individual locations.
Individual positions can then be selected for closer evaluation of specific deviations.
What pipe sizes can the KS 135 Scan measure?
The current KS 135 HD laser measurement system has a specified measuring range of 150 mm to 2,200 mm.
The wider KS 135 and FW 135 inspection platform can be configured for CCTV inspection from DN135, with larger crawler configurations available depending on the application.
How accurate is the KS 135 laser measurement?
Rausch specifies distance-measurement accuracy of no more than 1% from DN150 for the current KS 135 HD laser measurement system.
Measurement accuracy should be verified in accordance with the equipment operating and calibration procedures.
Can the results be viewed in 3D?
Yes. Once the scan has been completed, the measured pipe can be represented as a 3D tube with deformation displayed visually.
Cross-sectional and flat pipe-profile views can also be used to examine individual positions and understand how the measured profile differs along the reach.
