Sonic V

Innovative Inner Diameter Inspection System for Heat Exchangers and Boilers

Sound Wave Inspection Systems introduces the Sonic V, a Fifth Generation Acoustic Pulse Reflectometry inspection system for ultra-fast and reliable inner diameter tube inspections.


A powerful and flexible device

Incorporating cutting-edge technology, the Sonic V has been designed with speed and mobility in mind. The lightweight, ultra-portable, battery operated probe is small enough to be carried in a backpack, while the absence of cables or calibration tubes makes the Sonic V even easier to operate. Extremely quick data collection makes 100% inspections a reality when/if needed.

Designed for fast inspections

Highly sensitive to through wall holes (detects any hole with diameter of 0.5mm and bigger!), with under 10 seconds for single tube inspection, enables efficient testing of 100% of tubes in shutdowns and emergency inspections.

Top quality reports each time

The most experienced analysts are available 24/7, guarantee top quality analysis and reporting every time

Acoustic Pulse Reflectometry

Sonic V leverages APR technology capabilities

Specially formed acoustic pulses are propagated through the air enclosed by tube.
Echoes generated by defects are recorded using cutting edge microphones.
Powerful algorithms are identifying location, type and size of ID defects.

Quick Tour

From inspection preparation stage to final report in 4 easy steps:

The use of the Sonic V is very easy.

As a matter of fact it takes only 4 simple steps to get from preparing the inspection to having the final report ready.

Following those steps will take you through the inspection in a record time, where, once the data reaches the analysts, you will receive the report within no more than 24 hours.

Quick Tour
