A sound velocity table is a list of the speed of sound in various materials. This information is necessary to have when using our Touchstone 1 ultrasonic thickness gauge, as the speed the ultrasound will move through the material in question needs to be programmed into the gauge to obtain an accurate thickness reading.
The document lists various materials and their corresponding sound velocities when tested with ultrasound. It provides the velocity of sound in inches per microsecond and metres per second for over 30 common materials including metals, plastics, liquids and other substances.
This method served to estimate the ultrasonic velocity of each drop by measuring drop size and time-of-flight of ultrasonic transmission.
1 gru 2021 · The ultrasonic system can measure the ultrasonic velocity through ice at different temperature, salinity and density of ice. When ambient temperature decreased from 0°C to −30°C, ultrasonic velocity and mechanical properties of ice increased, and vice versa.
