Measurement Principle

Geometry Inspection Tool with Extended Resolution (RoGeo·Xt) for an accurate determination of dent size and other geometric properties
An accurate determination of dent size and other geometric properties in a pipeline requires 100% circumferential coverage by the geometry sensors. To achieve full coverage, RoGeo·Xt consists of two sensor units which are connected to each other.
Since the non-contact electronic sensor complements data obtained from the caliper arm, even sharp transitions on the internal surface (e.g. pipe misalignment at a weld joint) are recorded accurately.
The electronic sensor is insensitive to non-conductive material. This means that recorded data always refers to the metal internal surface of the pipeline rather than scale or wax.
The ROSEN RoGeo·Xt is equipped as standard with an electronic XYZ mapping system. This permits accurate navigation through the pipeline and determination of bend radii, bend length and bend direction.

"Mechatronic" design: combining mechanical and electronic measurement systems
This is how the "mechatronic" solution works: a touchless sensor is integrated inside the sensor head and a position sensor monitoring the mechanical position of the sensor arm is attached at the bottom. The function of the touchless electronic sensor is to compensate any unwanted inertia of the caliper arm. This "mechatronic" combination produces two key benefits:
1. it permits higher operating speeds compared to conventional tools.
2. it gives the RoGeo·Xt Geometry Inspection Tool substantially improved measurement accuracy which exceeds the typical requirements of the latest pipeline regulations.
In addition, the "mechatronic" design enhances sizing capabilities due to its lack of sensitivity to irrelevant factors such as scale or wax debris.
