The article puts some of the leak-detection metrics and selection criteria into perspective and illustrates the importance of various factors under different conditions. This is accomplished by using some hypothetical, yet realistic, examples of various leak incidents. The American Petroleum Institute's recommended practice API RP 1130 provides an overview of most of the leak-detection methods available for liquid pipelines, many of which apply to gas pipelines as well. Reliability measures the ability of a leak-detection system to render accurate decisions about the possible existence of a leak in the pipeline under defined conditions: how many false alarms the system will generate and how many real leaks it will detect. For most systems, there is a tradeoff between sensitivity and false alarms; the higher the sensitivity, the more false alarms. Robustness measures the leak-detection systems ability to continue to function and provide useful information, particularly under changing conditions of pipeline operation or situations where data is lost or suspect.
