The first ultrasonic thickness gauge was made in 1967 by Werner Sobek; [citation needed] a Polish engineer from Katowice. This first ultrasonic thickness gauge measured the velocity of the waves it emitted in particular test samples, it then calculated the thickness in micrometers from this speed measurement by an applied mathematical equation.
Phased array ultrasonics (PA) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing. Common applications are to noninvasively examine the heart or to find flaws in manufactured materials such as welds.

The frequency used in the inspection depends on the thickness of the structure, but guided wave testing typically uses ultrasonic frequencies in the range of 10 kHz to several MHz. Higher frequencies can be used in some cases, but detection range is significantly reduced.

The ultrasonic density meter calculates the sonic velocity by using the known distance between the transmitter and receiver and the measured transit time. The measuring instrument can now calculate the density, as it is dependent on the sound velocity. [3] Another method that is utilized in ultrasonic meters is the envelope energy average method.
