Ultrasonic flow meter — A ultrasonic flow meter measures the velocity of a liquid or gas through a pipe using acoustic sensors. This has some advantages over other measurement techniques. The results are slightly affected by temperature, density or conductivity.… … Wikipedia
Ultrasonic grating — An ultrasonic wave is a sound wave having a frequency greater than 20 kHz. Because of the very small wavelength of ultrasonic waves compared to X rays they have considerable penetrating power. The human ear can not recognize ultrasonic waves, but … Wikipedia
ultrasonic inspection — a means of locating defects in steel. When acoustic energy in the ultrasonic range is passed through steel, the sound waves tend to travel in straight lines, rather than diffusing in all directions as they do in the audible range. If there is a… … Mechanics glossary
ultrasonic inspection — A nondestructive test method that employs high frequency mechanical vibration energy to detect and locate structural discontinuities or differences and to measure the thickness of a variety of materials. Radiation frequency is of the order of 0.1 … Aviation dictionary

Time-of-flight — The time of flight (TOF) describes the method used to measure the time that it takes for a particle, object or stream to reach a detector while traveling over a known distance. In time of flight mass spectrometry, ions are accelerated by an… … Wikipedia
Internal rotary inspection system — (IRIS) is an ultrasonic method for the nondestructive testing of pipes and tubes. The IRIS probe is inserted into a tube that is flooded with water, and the probe is pulled out slowly as the data is displayed and recorded. The ultrasonic beam… … Wikipedia
