CALIPER - DDL

Not Your Average Geometry Tool
The Enduro Digitel Data Logger (DdL) offers both radius point readings and diametrical cross-sectional analysis; multiple channels are provided offering the ability to log pipeline anomalies in clock orientation. The gyro inputs provide the ability to determine bend radii and bend direction. GPS available for every Pipeline Line Listing Event.
For pipeline operators managing shorter segments (10 miles or less), Enduro’s Techless Caliper is the efficient solution you’ve been waiting for.
Designed specifically for ease of use, this tool eliminates the need for an on-site Enduro Field Technician—saving you time, cost, and coordination. With just three simple steps outlined in our Quick Start Guide (included with every tool), operators can confidently run a caliper inspection and gather results—fast.
THE DdL ADVANTAGE

- 100% true circumferential coverage
- Precise buckle and wrinkle measurement
- No technician required – perfect for short-run pipelines
- Fast deployment – only 3 easy steps in the included guide
- Quick results – inspect and review data faster than ever
- Reliable insights – designed to detect dents, deformations, and geometric anomalies
A Supporting Cast – AGM II
The Above Ground Marker (AGM) is available for all DdL surveys. Enduro’s traditional AGM equipment provides a reference location at specific points along the pipeline. These locations are logged directly to the DdL for future reference and location assistance.


XYZ Mapping & Everything In-Between
Global Positioning System (GPS) equipment works well with the DdL. Excavations may be determined from logged GPS readings and given in GPS excavation points.
With the use of twin gyros in the DdL, profiling and mapping of the pipeline is possible, as direction and angle readings are made on all bends. Bends are easily seen and may be used as reference locations when locating anomalies. Enduro’s DdL equipment is capable of traversing and recording bend radii of 1.5 times pipe diameter. (Bends of 1 diameter have been logged with special tool adaptation.)
*The AGM model shown is currently only available for the DfL tool. Coming soon for the DdL.
The DDL-DW2
Our newly developed Digitel Data Logger DW2™ ILI (the DdL DW2™) pig features advanced IMU navigation equipment that complements our PigProg software containing GIS tools connecting to a system utilizing ArcGIS.
