aCorresponding author: [email protected] Measuring Thickness of Object with Ultrasonic Thickness Gauge Fuao Han1, Li Zhang1,a and Kaige Cui2 1School of Physics, Tonghua Normal University, 134000, Tonghua, China, 2School of Aeronautical Manufacturing Engineering, Nanchang Hangkong University, 330000, Nanchang, China Abstract: In this paper, the .2012. A technique for independent thickness and velocity measurements, using laser ultrasonics, will be described. Thickness and velocity measurements are highly useful in the metal industrial both for controlling the thickness of the product where other techniques cannot be used but also for material characterisation considering both microstructural and mechanical .Ultrasonic thickness gauging is a widely used nondestructive test technique for measuring the thickness of a material from one side. It is fast, reliable, and versatile, and unlike a micrometer or caliper it requires access to only one side of the test piece.The ability to gauge thickness measurement without requiring access to both sides of the test piece, offers this technology a multitude of possible applications. Metals, plastics, ceramics, glass and other materials can easily be measured by portable ultrasonic thickness gauges with a common accuracy of.001”. Ultrasonic thickness gauges .

The 45MG is an advanced ultrasonic thickness gage packed with standard measurement features and software options. This unique instrument is compatible with the complete range of Olympus dual element and single . Thickness measurement of plate-like structures, typically performed by observing time-of-flight of transmitted or reflected ultrasound (US) is a routine non-destructive testing task [1], [2].The prevalent piezoelectric generation of US is normally restrained to a relatively narrowband testing frequency, which should be high-enough to achieve adequate resolution.Thickness measuring is essential across many industries to monitor corrosion, erosion and damage. Ultrasonic thickness measurement (UTM) is commonly used and the method can be applied to a wide range of structures and components that includes ship hulls, piping, pressure vessels and structural steel.The measurement of wind speed may be performed using ultrasonic transducers based on the principle of measuring the time-of-flight. However, due to the propagation of the ultrasonic signal in the medium of measurement, noises are added which can be modelled by different natures that affect the measurement accuracy of transit time and therefore the speed of the wind.
5.2 Ultrasonic thickness measurements are used extensively on basic shapes and products of many materials, on precision machined parts, and to determine wall thinning in process equipment caused by corrosion and erosion. .
