Guided Ultrasonics
QSR System – ALF
Manufacturer product description
An adjustable frame designed to support guided wave scanning on large-diameter pipes. It operates with the same sensor carts as the QSR1 ® configuration and forms part of the QSR ® System using circumferential propagation. The QSR ® ‑ALF positions only the sensor carts on the pipe, with the ePOD connected remotely via a rugged cable. This allows placement closer to the area of interest while maintaining a compact footprint suited to tighter spaces.
