Wavemaker® G5


The next generation of Guided Wave Technology.
Achieve precision testing effortlessly.

This instrument is the latest generation of renowned GUL Wavemaker® Pipe Screening System, developed specifically for advanced guided wave testing (GWT) of pipelines. Built on over two decades of field experience, the G5 introduces key enhancements in hardware performance, user interaction, and inspection workflow.

As asset owners seek faster, more efficient methods that minimise operational disruption, the G5 delivers improvements in data quality while reducing operator workload. The system combines a compact, ruggedised design with a powerful onboard computer and streamlined software environment—supporting efficient inspections whether in the hands of experienced users or newer technicians.

A Platform Designed for the Field

Every aspect of the Wavemaker® G5 has been purposefully reimagined to meet the rigorous demands of field‑based inspections. It’s compact enclosure, designed to IP54, and glove-compatible, ultra-bright toughened touchscreen ensure dependable operation across a range of challenging environments—including offshore, upstream, midstream, and downstream sectors, as well as buried and insulated pipelines. Dual hot-swappable batteries further support uninterrupted operation, enabling extended use without the need to pause for charging.

At the core of the system lies an integrated computing platform that streamlines the entire data acquisition‑to‑reporting workflow. The embedded WaveProX software enables direct instrument control, while compatibility with WaveProV on an external laptop offers added flexibility. Procedure-driven collection routines, combined with intelligent feature recognition tools, reduce inspection variability and support fast, confident decision‑making in the field.

Empowering the Front Line

The Wavemaker® G5 is designed with the inspector in mind—supporting confidence at every level of experience. For newer technicians, procedure‑based collection minimises the risk of user error and guides consistent, compliant operation from the outset. Built‑in prompts and software-assisted interpretation help standardise inspections, allowing users to focus on collecting quality data rather than managing system complexity.

For experienced inspectors and Level 2s, the G5 enhances oversight and control. Progress and performance can be monitored in real time via optional remote access, ensuring team members remain aligned with established procedures. The streamlined workflow also reduces cognitive load, enabling senior personnel to focus on decision‑making, supervision, and troubleshooting when it matters most.

Compatible. Intelligent. Efficient.

The G5 is designed to integrate effortlessly into existing workflows, supporting all GUL Screening Rings and non‑ATEX gPIMS® Monitoring Sensors for full backward compatibility. Whether upgrading from a previous generation or expanding your current setup, it offers future‑ready capabilities without compromising proven infrastructure.

A newly developed instrument‑to‑sensor cable ensures compatibility with existing rings, allowing users to benefit from the latest platform improvements in performance, reliability, and ease of use.

Ring configuration, size, and serial number are detected automatically, reducing setup time and eliminating manual entry. For Compact, HD, and HT rings, the system also detects orientation and reads pressure and temperature sensors—enabling intelligent communication between hardware and software.

A particular efficiency is the ability to simultaneously collect standard and high‑frequency screening data when using Compact rings populated with TRIO modules. This not only saves time in the field but also streamlines analysis and reporting by consolidating results within a single data file.

Guided Waves

Guided Waves

In ultrasound, there are two types of waves, namely the Guided Waves and Bulk Waves.The existence of these waves depends on the material geometry (shape, thickness) and the inspection frequency or wavelength. Therefore, at relatively low frequencies (~25 kHz), Guided Waves can exist in pipes (and other geometries) because the wavelength is relatively much larger than the wall thickness of the pipe. For example, guided wave signals at 25 kHz typically have a wavelength of 130 mm and pipe wall thicknesses are typically within the range of 3 to 40 mm (1/8 to 1.57 inch).

Torsional T(0,1) mode

T01 Mode

Longitudinal L(0,2) mode

L02 Mode

Different types or modes of guided waves can exist for different structures (e.g. pipes, plates, rails) since guided waves are dependent on the material geometry. In the context of pipe inspection, the two most common types of pipe guided waves modes for guided wave testing are the Torsional T(0,1) and Longitudinal L(0,2) modes. The fundamental Torsional and Longitudinal waves are analogous to the Shear and Compressional waves in Ultrasonic Thickness (UT) testing respectively.

Although these modes are roughly analogous to the UT waves and the terms ‘Guided Wave UT’ or LRUT is often used to describe the technology, the interaction with defects is often very different and specialist guided wave knowledge is needed to configure the system.

The Guided Waves can propagate along the pipe at velocities that can be determined from Dispersion Curves. The Dispersion curve is a graph of phase or group velocity against the signal frequency (or the product of frequency and thickness). This plot shows how the velocities of the guided wave vary according to the mode and frequency.

Our years of experience have been incorporated into the WavePro software, so that inspector does not need to understand the physics in this plot, but is able to concentrate on evaluating the integrity of the asset.


The plot above is the group velocity dispersion curves for an 8″ schedule 40 steel pipe generated using DISPERSE. The fundamental longitudinal L(0,1), torsional T(0,1) and flexural F(1,2), F(1,3) and F(2,3) wave modes have been labelled.
