One common application for this test method is ultrasonic thickness measurement, which is used to ascertain the thickness of an object such as when assessing pipework corrosion. . Pulse-echo and Through-transmission. Ultrasonic testing can be performed using two basic methods – pulse-echo and through-transmission. With pulse echo testing . The echo to echo technique offered by many manufacturers measures the time between two successive backwall echoes in the base material thus taking the paint thickness out of the equation. Some consideration should be given to the thickness of the base material as most vendors will state the base material should be at least .100” or 2.5mm in .In the field of industrial ultrasonic testing, ultrasonic thickness measurement (UTM) is a method of performing non-destructive measurement (gauging) of the local thickness of a solid element (typically made of metal, if using ultrasound testing for industrial purposes) based on the time taken by the ultrasound wave to return to the surface. This type of measurement is .
Ultrasonic pulse technology has been widely employed for thickness measurement in the industrial field. Generally, the ultrasonic transducer is required to be perpendicular to the test sample surface when using the longitudinal wave. However, the transducer posture deviation (i.e., incident angle) of ultrasonic beam relative to the local surface normal is always inevitable. In . The ultrasonic pulse echo technique has been widely employed for thickness measurements in manufacturing process control and product quality inspection [1, 2]. In pulse measurement patterns, the thickness is determined by the ultrasonic time-of-flight (ToF) and the wave velocity in the sample.

Cygnus 1 Ex: Specifically developed for use in explosive atmospheres, this gauge uses the Multiple-Echo technique to measure through coatings up to 20mm thick, .PosiTector UTG Ultrasonic Wall Thickness Gauges measure the remaining wall thickness of materials such as steel, plastic and more using ultrasonic technology. Ideal for measuring the effects of corrosion or erosion on tanks, pipes, or any structure where access is limited to one side. Select from corrosion, low frequency, precision, and multiple echo thru-paint models. Much effort has been put into determining methods to make accurate thickness measurements, especially at elevated temperatures. An accuracy of +/- 0.001 inches is typically noted for commercial ultrasonic thickness gauges and ultrasonic thickness techniques.
