<p>A leak detection system includes a pressure system that requires leak and/or pressure testing. A pressure sensor coupled to the pressure system senses a first pressure at time0, after which fluid pumping system provides a selected volume of test fluid to the pressure system. The pressure sensor senses a test pressure at time1 and at selected intervals 'n' to time(n+1) and transmits a signal reflect of the pressures at each time to a general purpose computer for recording and storage on a computer readable medium. An operating program is configured to calculate a leak detection value, which is a function of a ratio of the first pressure at time0and the test pressure at time1; the test pressure at time1 and the test pressure at time2; and so on to a test pressure at the timen and the test pressure at the time(n+1). A graphical output is configured to display the leak detection value as a function of time.</p> |
