Acoustic Eye
Based on patented Acoustic Pulse Reflectometry (APR) technology, breakthrough, non-invasive solution overcomes the limitations of many conventional inspection techniques which are slow, cumbersome and limited.

What is APR?
Acoustic Pulse Reflectometry (APR) is based on the measurement of one-dimensional acoustic waves propagating in tubes. Any change in the cross sectional area in the tubular system creates a reflection, which is then recorded and analyzed in order to detect defects.
How Does APR Work?
An acoustic pulse injected into a semi-infinite straight-walled tube will propagate down the tube without generating any reflections. This pulse can be measured by mounting a small microphone with its front surface flush with the internal tube wall, through a hole in this wall. The microphone will measure the pulse once only, as it passes over the microphone diaphragm. If however, the pulse encounters a discontinuity in cross section, a reflection is created. The amplitude and form of the reflection is determined by the characteristics of the discontinuity: a constriction will create a positive reflection, whereas a dilation (increase in cross section) will create a negative reflection. Neither of these discontinuities will change the shape of the pulse in their vicinity, but the reflection measured by the microphone will be an attenuated and smeared replica of the impinging pulse, due to propagation losses. A hole in the tube wall, on the other hand, will create a reflection having a more complicated shape, affected by the size of the hole and the radiation of acoustic energy to the space outside the tube
Following extensive R&D efforts, the manufacturer has developed the world’s leading tool for industrial tube inspection applications based on APR.
Our innovative tube inspection solution is designed specifically for detecting faults commonly found in industrial tube systems: leaks, increases in internal diameter caused by wall loss, and full or partial blockages. The handheld probe employs extremely short source tubes (approximately 20 cm), making it extremely portable and convenient. Building upon APR technology, AcousticEye has engineered a series of breakthrough algorithms that enable the system to isolate, and then identify the above faults automatically, with a measurement time of less than 10 seconds per tube.
