INGU Pipers®

Free-Floating Pipeline Inspection

Innovative, Non-Intrusive, and Data-Driven

​

Pipers® is a free-floating inspection device that uses acoustics, pressure, and magnetic measurements to detect leaks, gas pockets, sediment buildup, and structural changes in water and wastewater. Used across 1,000+ miles of pipelines in North America, it provides critical data without requiring shutdowns or external tracking.

​

Key Benefits

• Minimally intrusive. – Inserts through a 3-inch outlet or flange, flows naturally with pipeline operations

• Minimal Downtime – No need for live tracking; data is captured and processed post-inspection

• High Sensitivity – Detects leaks as small as 0.18 gallons/min in low-pressure applications

• Versatile Retrieval – Captured via manhole baskets, headworks bar screens, or rake systems

 

Deliverables

✔ Leak Detection – Ultra-sensitive acoustic sensors detect and pinpoint leaks
✔ Hydraulic Grade Line – 100 pressure readings per second provide a full pressure profile
✔ Magnetic Flux Analysis – Identifies welds, magnetic features, and metal loss per spool (ferromagnetic pipelines). For non-metallic pipe, magnetic feature detection can be provided.
✔ Buildup Detection – Pinpoints sediment/debris accumulation for proactive maintenance
✔ Air/Gas Pocket Detection – High-accuracy detection of air pockets affecting flow efficiency

​

With Pipers®, utilities gain actionable insights to prevent failures, optimize maintenance, and extend pipeline lifespan—all with minimal disruption.
