1. A leak detection system comprising:

  • a pressure system configured to hold a first volume of a fluid at a first pressure at time0;

    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 time1, said test pressure at time1 being greater than said first pressure at time0;

    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 time0, said test pressure at timen, and said time(n+1), and said pressure sensor being configured to transmit a signal reflective of said first pressure and said test pressure at each of said timen and time(n+1) to said general purpose computer;

    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 time1 and said test pressure at time2; and

    said test pressure at time3;

    through said test pressure at said timen and said test pressure at said time(n+1); and

    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.
