Many digital ultrasonic thickness gauges have internal memory that allows the storage of thousands of thickness readings. Some instruments have "sequential" data loggers that store the thickness values in a numerical series. These data loggers are easy to use and many allow the creation of multiple files. The multiple files are typically used to separate the storage of data from different pieces of equipment or different locations.

Keeping critical equipment on-line can be a challenging task. Monitoring the wall thickness of equipment subjected to corrosive chemicals, temperature and operational changes is both a safety and manufacturing concern. Thus, on-line testing of equipment is common in most plants. A traditional testing method is digital ultrasonic thickness gauging for the measurement of wall thicknes. This one method has become the most widely used method of assuring mechanical integrity of equipment items that are prone to erosion / corrosion.
