Ultrasonic measurement is a non destructive method which is applied to measure thickness of a wide range of structures or components that includes ship hulls, piping, pressure vessels and structural steels etc.
An ultrasonic thickness gauge works on a sound pulse that has been generated by an ultrasonic transducer which travels through a test piece and reflect back from surface walls. Wave Travelling Time is then calculated accordingly and measured thickness is determined instantaneously.
Thickness Measurement provides important decisive parameters to ensure safety of inspected structures or components like for e.g. Analyzing metal loss caused by corrosion, erosion or damages etc in accord with original metal thickness during which it was designed. Also it works as decision making parameter for replacement or repairs of parts in structure or components.
Precision Thickness of Steels (M.S., S.S., C.S., C.I.), Aluminum, Copper, Lead, Tin, Other Metals Alloys, Brass, Monel, Specific Alloys, Glass, Ceramic etc. can easily be determined by Ultrasonic.
- Couplant is used for transmitting ultrasonic waves between probe and test piece.
- Incorrect selection of couplant may cause error.
- Couplant should be taken in adequate quantity and must adhere evenly to test surface.
- For Smooth surfaces low viscous couplant like Machine oil must be used and for rough surfaces high viscous couplant like gel, glycerine must be used.
- Ultrasonic rays do not penetrate properly through laminated, compounded or porous material so accurate measurement of their test piece is not possible.
- While measuring Super thin materials( Less than 4mm), the displayed reading might be as big as twice the actual thickness, this type of sensor limitation is known as “Dual Deflection “.
- Another similar limitation is known as “Pulse/ Cyclic jumping” which results in showing readings bigger than actual.
- For curved surfaces (in Steels) radius of test piece must be above 10mm and wall thickness must be above 3mm
- Surface Roughness, Rust and Eroded Pits may cause haywire readings. Under certain cases there might even be no readings.
- In order to obtain satisfactory results the other side of the test piece must be parallel or co axial with test surface. Else there will be erratic readings.
- Few metals like Aluminium has tendency of surface oxidation, due to which errors may occur.
