Abstract
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 time t0, after which fluid pumping system provides a selected volume of test fluid to the pressure system. The pressure sensor senses a test pressure at time t1 and at selected intervals ‘n’ to time t(n+1) and transmits a signal reflective of the pressures at each time to a computer system for recording and storage on a computer readable medium. A software application operating on the computer system is configured to calculate a leak detection value, which is a function of a ratio of the first pressure at time t0 and the test pressure at time t1; the test pressure at time t1 and the test pressure at time t2; and so on to a test pressure at the timen and the test pressure at the time t(n+1). A graphical output displays the leak detection value as a function of time.
