Applications:

Based on ultrasonic measuring principle, thickness of metal and other materials can be measured. So, it can monitor the degree of thinning, caused by corrosion, of all kinds of tubes and pressure vessels during working process, and accurately measure the thickness of all kinds of plates and processing parts. This gauge is applied widely in fields, such as petroleum, chemical, metallurgical, shipbuilding, aerospace industry, etc.

Measuring principle:

Ultrasonic thickness gauge determines the sample thickness by measuring the amount of time it takes for a sound pulse, generated by an ultrasonic transducer, to travel through a test piece and reflect from the inside surface or a far wall. In Pulse-Echo mode it measures the time taken for the pulse to travel from backwall, consequently measuring the total thickness of the sample. In Echo-Echo mode, it measures the time taken between the first echo and the next, thereby eliminating paint or coating thickness and measuring total thickness minus the coating thickness, hence, called through coating thickness.
