Ultrasonic examination (UE) provides a more detailed analysis of cylinders than hydrostatic testing and can detect corrosion and flaws better. UE does not require draining contents, de-valving cylinders, or handling temperature changes. It also has a lower rejection rate than subjective visual inspection. Digital Wave manufactures digital UE systems that can test all cylinder sizes with one machine and provide flexibility to adapt to changing regulations.

4. www.digitalwavecorp.com Hydrotests only give an average wall thickness Measuring the displacement of the water can only represent an average of the cylinder’s wall thickness Why UE? Why UE?

5. www.digitalwavecorp.com A signal is emitted from a transducer; when the signal meets a flaw in the cylinder, it is reflected back to the transducer. How Does UE Work? How Does UE Work? Flaw Scan Thickness Scan

6. www.digitalwavecorp.com www.digitalwavecorp.com Digital UE measures actual wall thickness. Gouges and pitting that don’t meet the reject requirements in CGA C-6 won’t cause rejects. Don’t let a subjective visual throw away your good cylinders. UE has a lower reject rate than visual! Actual Wall Thickness The Digital Wave Difference The Digital Wave Difference

8. www.digitalwavecorp.com Digital Wave systems are capable of handling cylinders from 3.2” D to 10.5” D, and lengths from 0” to 65” There are no proprietary electronic components --parts can be purchased easily, worldwide . The Digital Wave Difference The Digital Wave Difference

9. www.digitalwavecorp.com The DOT requires at least a 10% beam overlap for UE systems; Digital Wave's system provides a 25% beam overlap . UE systems come in two formats: digital (newer technology) and analog (older technology). Digital systems digitize the waveforms and store them in the computer. This permits an infinite variety of analysis to be performed providing complete flexibility to adapt to your future needs . To do this with analog systems you have to redesign the electronic circuits. Digital Wave, as the name implies, manufactures digital systems . All UE systems are NOT created equal!

10. www.digitalwavecorp.com The simple, single-sensor head design and multiple-axis motion control allow for all cylinder sizes to be tested with one machine. With Digital Wave's innovative design, just swap out the 2.25MHz sensor with a 3.5MHz sensor to test small cylinders. No other UE machine has this capability!

11. www.digitalwavecorp.com Digital Wave systems scan out-of-round cylinders with ease and feature automatic cylinder size detection. Digital Wave systems scan through most labels and bonded paint. They also won't reject on most draw marks or clear coat scratches. The Digital Wave Difference The Digital Wave Difference
