Abstract:
1. A leak detection system comprising: a pressure system configured to hold a first volume of a fluid at a first pressure at time a fluid pumping unit coupled to said pressure system, said fluid pumping unit configured to supply a selected volume of a test fluid to said pressure system, said pressure system holding said first volume and said selected volume at a test pressure at time a general purpose computer configured to accept and store an operating program and data as a function of time; at least one pressure sensor coupled to said pressure system and said general purpose computer, said pressure sensor being configured to sense said first pressure at time said operating program configured to calculate a leak detection value, said leak detection value being a function of a variance of said test pressure at time a graphical output operably coupled to said general purpose computer, said graphical output configured to display said leak detection value as a function of time.
