GAO Feng1, ZHENG Yuan-ming2. Experimental study on measuring sound velocity and distance using ultrasonic sensor[J]. 2009, 28(11): 68-70. DOI: 10.13873/j.1000-97872009.11.036.
A new experimental device using ultrasonic sensor is designed to measure the ultrasonic velocity and distance in material.This experimental device can be used to measure the ultrasonic velocity in solid
liquid and gas
and also detect objects in water
the depth of water and defects in workpiece.It can be used in medical science for measuring the thickness and position of human organs.The experimental results show the uncertainties are less than 3%.
