Inoex GmbH reports that its Aurex digital ultrasonic measuring technology now can be used on multilayer foam-core pipes made from PVC and polypropylene.
The internal air bubbles on foam-core pipe can make it difficult to measure the pipe, since the bubbles reflect ultrasonic signals.
Inoex has developed control algorithms that tune out these overlapping ultrasonic echoes, to accurately calculate wall thickness of each layer.
Aurex uses a series of fixed sensors to continuously measure pipe wall thickness, diameter, shape and layer thickness.
Inoex is based in Bad Oeyhausen, Germany. Its U.S. unit, Inoex LLC, is in Lancaster, Pa.
