The Solution

ROSEN’s Pipeline Data Loggers (PDL and ATE X PDL) are designed to collect and store operational data during a pipeline inspection. They provide operators with detailed time dependent data such as temperature of the medium, pressure conditions in the pipeline, differential pressure and acceleration.

The PDL is designed as a stand-alone unit, which can be added to any pipeline cleaning or inspection tool from 4” to 56”. The newest development is ROSEN’s ATEX PDL which offers several advantages, such as indication of bends including bend angle.

The user-friendly software makes it easy to configure and read out the stored data. All data can be analyzed based on various criteria and visualized with ROSEN software.

By analyzing the data it is possible to use recorded temperature profiles for wax models, to detect and locate restrictions and deposits, monitor tool behaviour, assess cleaning progress and effectiveness, and verify pipeline conditions.


The provided software allows tiled displays of the different measurement criteria. It is an intelligent platform to select and synchronize time frames of a particular interest. We offer full service that includes the data acquisition and reporting of your survey results.


The PDL can be attached to any standard cleaning tool and employs fast response, low current sensors which can record for more than 30 days and up to 500 km (310 miles) of inspection. Data are presented in an easy to understand graphical format using supplied software.
