Coatings up to 6mm thick, whether they are paint, epoxy or bitumen, do not present any problems. Minimal preparation of the surface is required, saving a considerable amount of both time and money. Multiple Echo also automatically verifies each measurement before displaying the reading, which means no erroneous measurements are displayed. This technique is used throughout their range of gauges that have been designed with specific applications in mind.
Other features include no probe zeroing, no re-calibration at switch on and protective membranes fitted to the probe face prevent damage to the probe and keep cost of ownership low.
Only Multiple Echo can give the true substrate thickness and ignore coatings up to 6mm thick. With Multiple Echo, readings are taken by measuring the time delay between three consecutive back-wall echo’s which means that the coating thickness is completely ignored. The times of T2 and T3 are equal to the time that it takes to just travel through the metal. Only by looking at three echoes can the measurements be automatically verified (where T2 = T3).
Multiple echo measurement means:
- Coatings do not have to be removed measures only the metal thickness
- No grinding minimum surface preparation
- Measures on rough, uneven surfaces
- Fast accurate reliable
- No false readings repeatable results
- Easy to use minimum operator training
- Greatly reduces inspection time and cost
- Recommended by Classification Societies when measuring through coatings on ships
