Ultrasonic Wall Thickness Meter

The ultrasonic wall thickness gauge emits high-frequency sound waves into the material through a probe. The sound waves reflect off the inner wall of the material and return as echoes. The instrument calculates the round-trip time difference of the sound waves and converts it into thickness based on the material's sound velocity. It is used to measure the wall thickness of objects such as pipes and containers that can be accessed from one side, and is commonly applied in chemical equipment and pipeline maintenance to inspect corrosion-induced thinning.
Selection
When selecting, consider that the measurement range should cover the thickness of the object to be measured, the precision should meet the error requirements, and the probe frequency should be compatible with the material type. High-temperature environments require high-temperature probes. Check the calibration certificate and the adjustable material sound velocity function. Portable models are suitable for on-site use, while fixed types are suitable for production lines.

Ultrasonic Thickness Gauge Selection: Technical Considerations for Probe Configuration and Measurement Modes
This article primarily introduces the technical factors to consider when selecting an ultrasonic thickness gauge. In terms of probe configuration, the frequency affects both resolution and penetration depth, while crystal size determines adaptability to curvature and surface conditions. Dual-element probes offer a smaller dead zone compared to single-element probes, and delay-line probes are suitable for thin-wall and high-temperature applications.
Ultrasonic thickness gauge for detecting thick coatings and composite coatings.
Ultrasonic thickness gauges measure coating thickness using the principle of ultrasonic pulse reflection, calculating the result based on the propagation time of sound waves in the material and the speed of sound. When detecting thick coatings and composite coatings, challenges such as acoustic attenuation of the material, unknown sound speed, and signal recognition at multi-layer interfaces must be addressed.
