CP4 sensor

We are leaving the gas N2 bottle connected to lower sensing line overnight. I lowered the N2 line pressure from 180 psig to 100 psig and re-connected the rotameter and adjusted it so if the blockage does break loose flow into LN2 reservoir will be limited to 3 LPM.

Attached is photo of pressure regulator values for Kyle and John. ;)

I will finish installing TCs tomorrow and hope my fingers don't fall off in the process.

I also lowered CP4 LLCV to 38% open because exhaust pressure was reading 0.3 psig when we expect 0 psig with bypass valve open.
