Quantitative leak testing with tracer gas probes
Quantitative leak testing with tracer gas probes
(OP)
Dear all,
I am hoping someone can point me towards the right direction when it comes to selecting a tracer gas and probes to determine the leakage rate along the seal of a large opening.
The opening is roughly 16 ft by 16 ft and due to the awkward shape it is next to impossible impossible to place a vacuum box. Unfortunately due to the space around it and its shear size I cannot perform a pressure change test either.
The only feasible solution I can think of is to create a pocket of gas with plastic sheeting along the seal and use set tracer gas and probe.
I would gladly hear anyone's take on this.
Cheers,
Alex

I have seen work done on very large structures using SF6 as a tracer (common in power plants).
The traditional gas is He, but that may be way more sensitive than you need.
