Investigating Or Analyzing Materials By The Use Of Ultrasonic Waves
(AREA)
Abstract
Improvements in ecometers, characterized by comprising means for periodically transmitting impulses of pressure waves, and for receiving pulses of reflected pressure waves, and means dependent only on the most energetic reflected impulse, received during each pulse period to produce a representative indication signal of the time interval between the moment of reception of said superior, reflected impulse, and the moment of transmission of the last transmitted impulse above.
