How to Choose the Right Model

Whether you are purchasing your first ultrasonic thickness gauge or replacing an existing instrument, this guide will help you evaluate the most important requirements.

1. What Is an Ultrasonic Thickness Gauge?

An Ultrasonic Thickness Gauge is a non-destructive testing instrument used to measure the thickness of suitable solid materials.

The instrument sends ultrasonic sound pulses into the material through a probe.

When the ultrasonic energy reaches a suitable reflecting boundary, part of the sound returns to the probe.

The instrument calculates the thickness using the measured echo travel time and configured sound velocity.

Basic Measurement Formula

Thickness = Sound Velocity × Echo Travel Time / 2

Because the ultrasonic pulse travels into the material and returns to the probe, the total travel distance is twice the material thickness.

Main Advantages

One-Side Access

Suitable components can be measured without access to both sides.

Non-Destructive Measurement

Thickness can often be checked without cutting the component.

Portable Operation

Handheld instruments are convenient for factory and site inspection.

Maintenance Documentation

Thickness readings can be recorded and compared during future inspections.

Industrial Versatility

Suitable applications may include steel plates, metal pipes, tank walls and machinery components.

Actual performance depends on the material, probe and measurement conditions.

Thickness measurement can help identify wall thinning at selected inspection locations.

Example of Thickness Monitoring

Consider a hypothetical steel pipe inspected over several years.

Inspection YearMeasured Thickness20236.0 mm20245.9 mm20255.7 mm20265.5 mm

Illustrative example only.

The recorded thickness decreases from 6.0 mm to 5.5 mm.

Average Historical Thickness Loss

Thickness Loss = 6.0 - 5.5 = 0.5 mm

Average Historical Loss Rate = 0.5 / 3 = Approximately 0.167 mm per year

This is a simple historical calculation.

Actual corrosion rates may change, and measurement uncertainty must be considered.

Important Reminder

Thickness monitoring helps identify possible material loss but does not automatically detect every localized corrosion defect.

For critical equipment, use appropriate inspection procedures and engineering assessment.
