Pulse Echo Ultrasound
Definition - What does Pulse Echo Ultrasound mean?
Pulse echo ultrasound refers to a corrosion diagnostic technique that involves short-duration sound waves with frequencies above the upper limit of human hearing capability. It is often used to detect corrosion or other physical abnormalities in a metallic object.
Corrosionpedia explains Pulse Echo Ultrasound
The process of pulse echo ultrasound techniques involve the transmission of ultrasound pulses into the metal subsection being examined. Echo signals resulting from the contact are bounced, reflected or otherwise scattered from the metal's surface in response. The degree of reflection is representative of the depth the wave has traveled into the surface. There is a directly proportional relationship between the distance traveled by the wave, the length of delay between pulse transmission and echo reception, and the degree of corrosion present in a metallic object.
