Thanks to [one of GUL's experts], I was finally able to get the correct setup for data collection and analysis on high noise pipelines.

... Then, I was successfully able to get data from pipelines for which collection had previously failed due to High Noise Level, while also confirming that the initially poor Signal‑to‑Noise ratio was far improved: from 20dB to 60dB.

... Through the comments posted and shared on GUL Facebook, I became aware that GWT using Compact rings and modules allows easier detection of even smaller defects, a more efficient operation, and clearer signal.

... I do appreciate GUL's readiness to help us.
