online thickness gauge for plastic pipe production process

Our company is a professional plastic pipe wall thickness measurement supplier. This kind of online thickness gauge for plastic pipe is used for the uninterrupted online real-time measuring and monitoring of the change of the thickness, outer diameter, eccentricity and out-of-roundness in the whole production process of gas pipe, water supply pipe, conduit pipe, medical catheter, etc. Therefore, the quality risks can be completely eliminated in production process.


1. The sensitivity of ultrasonic wave processor combined with our technology can realize all-round coverage of pipes and a measurement of different speed tubes. The highest measurement of linear velocity can reach to 100m/min.

2. This wall thickness measurement is suitable for measuring all kinds of material pipes (like PE, PVC, PERT, PP, etc) and also can used in the areas of all pipes (like gas pipe, the heating pipe, drain-pipe, etc.).

3. The measurement consumption is less than 30w.

4. Our online thickness gauge for plastic pipe can lower and completely eliminate the quality risk in the production of plastic pipes and improve product quality.

5. It can shorten the starting time and reduce the rejection ratio.

6. Perfect recording and filing function of production data.

7. The wall thickness measurement can automatically generate a statistics form of pipe quality.

Working Principle

The measurement principle of probe is as following:

The ultrasonic probe distribution structure is as following:

1. The built-in fixed ultrasonic transmitter can measure various range of pipe wall thickness.
2. The number of ultrasonic probe: 4, 8, 16
3. The protection grade of the ultrasonic probe is IP68, thus it can be directly fixed to the scanning box, and whole installed inside of the water tank (determined on specific model).
4. The probe of the online thickness gauge for plastic pipe can measure the thickness of multi-layer pipe, and the thickness of each layer can be displayed separately (optional).

Probe: ULTRAMAC 315-4T

Measurement range of external diameter: 110-315mm
