as an estimation, we have two ways, but not accurate100%

A- according to working pressure measurements

- get the normal working pressure, & gas weight from catalogues.

- get the actual working pressure from measurement.

- as a known base PV=MRT, so (P) directly proportional to (M), then we can get estimation for the quantity of gas.

B- according to ampere difference measurements at the ideal case and actual case.

you don't need to calculate the amount of gas that has leaked out!.....just fix the leak and fill the system with gas upto the previous normal working pressure.

There is no direct way to calculate gas weight.

therefore there is No need to calculate the exact gas. Just maintain the previous pressure which was before the leakage and you can get the volume of weight to be added

 

Hope this will work.
