ABSTRACT:
The invention generally relates to a system and method for integrated gas delivery and leak detection to one or more applications. The system includes at least one application site, a process conduit extending from a process gas source site to the application site, a first and second process flow control at the process conduit, and a first pressure sensor.Also included in the system is a microprocessor that is in electronic communication with the flow controls and the first pressure sensor, wherein the microprocessor is programmed to respond to an application standby request by performing a pressure decay test, including closing the second process flow control and pressurizing a portion of the system by opening the first process flow control. Further included in the pressure test is closing the first process flow control when the pressure at the first pressure sensor is at a minimum pressure, and comparing an empirical pressure decay rate at the first pressure sensor with a maximum pressure decay rate, whereby an empirical pressure decay rate that exceeds the maximum pressure decay rate indicates the presence of a leak.
