Technology Overview

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.

  • Probe injects acoustic pulse down the tube
  • Returned echoes generated by defects are recorded and analyzed
  • Patented algorithms identify and report exact location, type and size of inner diameter defects
