[Dsg-rich] DA for RICH N2 system upgrades

[Tyler Lemon]

Hello Bob, 

DSG has rotameters and flowmeters on hand to upgrade RICH's nitrogen supply panel to increase the maximum flow it is capable of. Attached is George's system diagram showing the upgraded panel and his Excel sheet listing all hardware that will be used. 

Because you are system owner of RICH's gas system, you will need to request and assign a Design Authority. We would need the DA to approve the changes and determine the appropriate orifice size for the upgraded panel. 

Since we have the parts on hand, we would be able to install the upgraded components on the panel as soon as DA approval is given and the experimental run ends. 

Best regards, 
Tyler
