Acoustic Pulse Reflectometry Probe injects an acoustic pulse down the tube Returned echoes generated by defects are recorded and analyzed A set of proprietary, patented algorithms identifies and reports exact location, type and size of inner diameter defects Convenient Handheld Device The compact Dolphin G3™ handheld comprises the entire non-invasive probe assembly. This includes customized adaptors to fit tubes of any internal diameter up to 4”, a transducer, microphone, controls and LCD screen. Inspection setup is performed via a connected external computer that also records and analyzes test data using specialized AcousticEye software. User-Friendly Operation Dolphin G3™ guides the technician through all the steps necessary to carry out a job - tube sheet mapping, parameter input, measurements, verification and report generation. An intuitive graphic user interface, including helpful right- click functions, makes scrolling, zooming and navigation easy every step of the way. Mapping: The system creates a computerized model of the heat exchanger tube sheet based on a photo, CAD file or scanned schematic diagram. Automatic numbering and mapping is used to establish test plans and track inspection progress. Logging: All measurements are logged in their raw form. Different thresholds and algorithms can be applied to regenerate reports with varying levels of sensitivity. One-click calibration: The system utilizes only a single calibration tube (supplied), eliminating inventory requirements and typical calibration challenges. Visual aids for defect detection: Programmable thresholds for different flaw types and sizes can be overlaid on the measured signals to assist in visual evaluation of defects. Computer-based interpretation: Delivering objective, consistent and actionable results, the system automatically performs computer-based data interpretation, reducing the reliance on experts. Report generation: Dolphin G3™ presents an easy-to-read online report (with drill down options) to the technician for verification, as well as a final summary report including tabular reporting and screenshots of the detected flaws in PDF or HTML format.
