ABSTRACT:
A hydrocarbon leak detection system has a microprocessor based controller for receiving inputs from transducers and comparing the inputs against stored decision criteria to determine if hydrocarbons are leaking. The controller can receive and distinguish inputs from line pressure probes used for a product line tightness test, compare the line pressure probe inputs against stored decision criteria to determine status, and report the status.
