INVESTIGATOR™
AQUAM
The Investigator™ is an asset management and leak detection tool for insertion into pressurized pipelines up to 150psi.
The Investigator™ is a pressurized pipe inspection and leak detection system and is designed for 3' diameter pipework and above. Access through fire hydrants*, 1.5' and above pressure fittings, air valves, and gate valves at full mains pressure.
The system is mounted onto pipework through a selection of fittings and/or “hot tappings.” This process makes access into the pipework simple and cost effective.
The Investigator is available in two variants, the Pro and E.
Monitoring the real-time data captured by the camera and hydrophone sensor head allows the operator to understand internal pipework conditions and identify leaks. A 300ft (100m) cable is supplied with the system which potentially offers a maximum inspection distance of 600ft (200m) upstream and downstream of the insertion point. This is influenced by pipe diameter, internal condition and the configuration of the pipe.
The software is specific for the Investigator™ technology and is used to control the sensor head and view both video and acoustic results from live surveys. The software displays video in a resizable window and also acoustic results in order of amplitude and frequency. The software also operates the sonde which is built into the camera sensor head. The system is compatible with LiveFeed software for maximum performance.
