When using an automatic tank gauge for single wall tank leak detection, what type of data report does it generate?

1. Monthly performance summary

2. Post-test, hard copy data report

3. Real-time leak monitoring data

4. Daily operational report

The correct answer is: Post-test, hard copy data report

An automatic tank gauge (ATG) for single wall tank leak detection generates a post-test, hard copy data report. This type of report summarizes the results of the leak tests conducted by the ATG after a testing period has concluded. It provides a permanent record of the tank's performance, which is crucial for compliance with regulatory requirements and for documentation purposes. The report typically includes details such as the time of the test, the amount of product in the tank before and after the test, and any detected changes, which helps in assessing the integrity of the tank. While other options describe different types of information, they do not align with the specific function of an ATG in leak detection after a testing event. For instance, a monthly performance summary would detail ongoing metrics over a month but wouldn't provide the immediate conclusion of a leak test. Real-time leak monitoring data refers to ongoing assessment rather than post-event results. Daily operational reports might include ongoing operational data but lack the specific findings from a formal leak test. Thus, the post-test, hard copy data report directly corresponds to the function and output of the ATG after running a leak detection test.
