[Dsg-mvt] MVT EEL Gas Setup

[Amrit Yegneswaran]

brian thanks for the status. 



    1. matt did you check the the system for leaks after stephan and brian did? 
    2. matt does the system have to be checked again after installing the new gauge. 
    3. brian, so franck's e-mail (06/12/17) suggesting a leak was erroneously based on the reading on the high pressure side, right?

Amrit wanted a summary of what happened with this gas system while he was on vacation. 

1) Bob Miller (the system owner) requested to have a leaking relief valve replaced, the single valve was replaced with two as per Matt Marchlik (the DA for the system) to have enough flow. This was leak checked by DSG using snoop as well as Stephan with their sniffer and he reported it as okay. 

2) A replacement gauge for the high pressure side of the pressure regulator was selected by Matt, PR placed by me on 6/9, and ordered today by procurement. Once it arrives we'll meet with Matt in order to get it installed. 

3) The gas bottle that was installed Friday afternoon still reads 0 on the high side and 15 psi on the low side as of this email, so it looks like the estimate of 5-7 days from Franck is in the ballpark as it has lasted just shy of 4 days so far.
