When utilizing an automatic tank gauge for single-walled tank leak detection, what information is NOT generated in the post-test hard copy data report?

1. Liquid volume

2. Fuel depth

3. Outside air temperature

4. Time and date of test

The correct answer is: Outside air temperature

The post-test hard copy data report generated by an automatic tank gauge for single-walled tank leak detection typically includes important information such as liquid volume, fuel depth, and the time and date of the test. These details are crucial for analyzing the performance of the tank and determining whether a leak is present. Liquid volume provides insights into the amount of fuel in the tank, which helps in assessing whether there has been any loss of product during the test. Fuel depth measures how much fuel is present above the tank's bottom, critical in performing calculations for potential leaks. The time and date of the test are necessary for record-keeping and for tracking any changes over time. In contrast, outside air temperature is generally not a data point included in such reports, as it does not directly relate to the tank's operation or the testing for leaks. It's more relevant for atmospheric measurements and has little bearing on the integrity of the tank itself. Thus, the report focuses on parameters directly influencing the tank's performance and operational status, making outside air temperature not pertinent for leak detection assessments.
