This technology has a lot of potential uses because it can measure thickness without having to get to both sides of the test piece. Ultrasonic thickness gauges, which measure a part's thickness by measuring the time sound travels from the transducer through the material to the back end of a part and then measures the time of reflection back to the transducer, can easily measure metals, plastics, ceramics, glass, and other materials with an accuracy of. 001 inches. The gauge then uses the speed at which sound travels through the material being tested to determine the thickness. A couplant is required for the pulse/echo ultrasonic thickness gauge's direct contact method. While propylene glycol is commonly used, there are numerous other options. Metal Testers gives the best.
