Note: To make sure the probe working properly it needs to use couplant to isolate the air between the probe surface and the measured workpiece surface.
Measuring Principle:
The principle of the ultrasonic thickness gauge is to generate ultrasonic pulses through the probe. The pulse enters the workpiece from the contact surface of the probe and the workpiece, propagates in the workpiece along the thickness direction, and reflects on the other surface of the workpiece. By measuring the total time (t) of the ultrasonic pulse propagating in the workpiece and the velocity (v) of the ultrasonic pulse, we can obtain the relationship between the thickness (H) of the workpiece with the time (t) and velocity (v):
H =vt/2
Where:
H - Thickness of the test workpiece.
v - Sound Velocity in the workpiece.
t - The measured round-trip transit time
Note: To make sure the probe working properly it needs to use couplant to isolate the air between the probe surface and the measured workpiece surface.

Applicable condition
- The surface of the measured workpiece should be clean. If it is rough or seriously corroded, coupling agent should be used on the surface, or treat the surface of the measured workpiece with rust remover, wire brush or sandpaper.
- Ensure that the surrounding environment has no strong vibration, no strong magnetic field, no corrosive media, and serious dust.
- The probe should be selected according to the thickness and shape of the measured workpiece.
- Especially suitable for standard workpieces and pipelines.
