Whether you are a maintenance engineer, QA/QC technician, inspection contractor or industrial purchasing manager, this guide will help you understand ultrasonic thickness measurement and select an appropriate instrument.

 

1. What Is an Ultrasonic Thickness Gauge?

 

An Ultrasonic Thickness Gauge is a measuring instrument that uses ultrasonic sound waves to determine the thickness of suitable solid materials.

 

The instrument sends ultrasonic energy into the material through a probe.

 

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

 

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

 

Basic Measurement Formula

 

Thickness = Sound Velocity × Echo Travel Time / 2

 

The division by two accounts for the sound travelling into the material and returning to the probe.

 

Main Advantages

 

Non-Destructive Measurement

 

Suitable materials can be measured without cutting through the component.

 

One-Side Access

 

Only one accessible surface may be required.

 

Portable Inspection

 

Handheld instruments are convenient for factory maintenance and site inspection.

 

Corrosion Monitoring

 

Repeated measurements may help identify possible wall thinning at selected locations.

 

Quality Control

 

Thickness readings can support material verification and inspection documentation.

 

Important Limitation

 

An ultrasonic thickness gauge measures thickness. It does not automatically detect every crack, corrosion pit or internal defect.

 

Specialized ultrasonic flaw detection equipment may be required for other inspection purposes.

 

2. Ultrasonic Thickness Gauge vs Conventional Measuring Tools

 

Different measuring instruments are suitable for different applications.

8. Ultrasonic Thickness Gauge for Corrosion Monitoring

 

Corrosion Monitoring is an important part of industrial preventive maintenance.

 

Metal equipment may gradually lose thickness due to corrosion or erosion.

 

Example of Historical Thickness Measurements

 

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

 

Illustrative values only.

 

Thickness Loss Calculation

 

Thickness Loss = Initial Thickness - Latest Thickness

 

Thickness Loss = 6.0 - 5.5 = 0.5 mm

 

Average Historical Loss Rate

 

Average Loss Rate = 0.5 mm / 3 Years

 

Average Loss Rate = Approximately 0.167 mm per year

 

This simple calculation illustrates historical thickness change.

 

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

 

Important Reminder

 

Ultrasonic thickness measurement does not automatically detect every localized corrosion pit or determine equipment safety.

However, a comprehensive machinery inspection may also require:

 

Visual inspection

 

Mechanical checks

 

Electrical testing

 

Operational testing

 

Vibration measurement

 

Safety assessment

 

Thickness measurement alone cannot determine the overall condition or remaining service life of used machinery.

 

12. Understanding Sound Velocity Settings

 

Sound Velocity Setting is essential for reliable ultrasonic thickness measurement.

 

Different materials transmit ultrasonic sound at different speeds.

 

Typical Longitudinal Sound Velocity Values

 

MaterialApproximate Sound VelocityCarbon Steel5920 m/sStainless Steel5740 m/sAluminium6320 m/sCopper4760 m/s

 

These values are general references. Actual sound velocity varies with material composition, structure and temperature.

 

Why Incorrect Velocity Causes Errors

 

If the instrument uses an incorrect sound velocity, the calculated thickness may be wrong.

 

Recommended Practice

 

Identify the material.

 

Use an appropriate reference.

 

Verify the sound velocity setting.

 

Record the setting when required.

 

Repeat verification when changing materials.

 

Do not assume that every steel alloy uses exactly the same sound velocity.

 

13. Ultrasonic Probe Selection Guide

 

Probe selection affects measurement capability.

 

10 mm Probe

 

A compatible 10 mm probe may be suitable for:

 

Flat steel plates

 

Large accessible metal surfaces

 

Suitable large-diameter pipes

 

General industrial components

 

6 mm Probe

 

A compatible 6 mm probe may be useful for:

 

Smaller measurement areas

 

Certain restricted locations

 

Selected curved components

 

GM100 Plus

 

Supports a 10 mm probe.

 

GM130

Important Buying Advice

 

Confirm:

 

Material type

 

Expected thickness

 

Pipe diameter

 

Surface condition

 

Probe compatibility

 

Required measurement accuracy

 

A smaller probe does not automatically guarantee accurate measurement on every small-diameter pipe.

 

14. Can Ultrasonic Thickness Gauges Measure Through Paint?

 

Many industrial steel components have protective coatings.

 

Conventional ultrasonic thickness measurement may be affected by paint or coating layers.

 

The Benetech GM100 Plus and GM130 should not be assumed to provide specialized through-coating thickness measurement.

 

If the application requires measuring the metal substrate without removing paint, a specialized through-coating instrument may be necessary.

 

Where permitted, approved coating removal at selected measurement locations may be required.

 

Important Consideration

 

Before purchasing, confirm whether the measurement surface is:

 

Bare metal

 

Painted steel

 

Coated piping

 

Corroded metal

 

Rough fabricated material

 

This helps determine the appropriate measurement method.

 

15. Ultrasonic Thickness Gauge Calibration and Verification

 

Reliable thickness measurement requires appropriate instrument verification.

 

What Is Calibration?

 

Calibration establishes the relationship between instrument indications and reference values under specified conditions.

 

What Is Verification?

 

Verification checks whether an instrument meets specified requirements.

 

Recommended Procedure

 

Inspect the instrument and probe.

 

Confirm the material sound velocity.

 

Use a suitable known-thickness reference.

 

Apply coupling gel.

 

Measure the reference.

 

Compare the reading with the established value.

 

Evaluate the result against the relevant acceptance criteria.

 

Record the verification.

 

Important Reminder

 

A built-in automatic calibration function does not automatically replace documented laboratory calibration or metrological traceability requirements.

 

For QA/QC applications, confirm the applicable calibration and documentation requirements.

 

16. How to Calculate Thickness Measurement Error

 

A basic measurement error can be calculated using the difference between the indicated thickness and reference thickness.

 

Formula

 

Measurement Error = Indicated Thickness - Reference Thickness

 

Example

 

Reference thickness: 10.00 mm

 

Displayed thickness: 10.08 mm

 

Measurement Error = 10.08 - 10.00 = +0.08 mm

 

Percentage Error

 

Percentage Error = (Measurement Error / Reference Thickness) × 100%

 

Percentage Error = (0.08 / 10.00) × 100% = 0.8%

 

Important Consideration

 

The calculated error does not automatically establish whether an instrument passes or fails.

 

Acceptance depends on the relevant tolerance, reference uncertainty and measurement requirements.

 

The example is illustrative and does not represent a verified GM100 Plus or GM130 accuracy specification.
