pablo,
thanks for re-sending me the documents.
for the solenoid, what is the flow rate,  now that delta P is set to 3.3 bars?
i'm confident it complies with danfysik recommended flow rate.
hopefully my confidence isn't misplaced like my spectacles!

expansion chamber is a cool idea
if the lead to the chamber is sized appropriately we could liquefy the nitrogen gas a la joule-thompson  and return it. (really!)

tyler, pablo, brian,
from the info you all gave me this afternoon, i think the controller is dying
but then again what/who  isn't?
i recommend that you all recommend that we buy a new controller, since there is no spare.
Goodnight & Godbless
