CP4 experiment 
The plan is to overfill CP4 this afternoon up to 100%, disconnect the flow meter from the exhaust pipe, then time how long it takes to pour LN2 out the exhaust (just like we do for a CP3 overfill), and then reconnect the flow meter, while leaving CP4 in manual mode over the weekend. I will monitor it from home. 

NOTE:  CP4 overfill will generate an alarm

Filled CP4 to 100% with flow meter connected. Then disconnected flow meter and filled until LN2 flowed out exhaust ports - took 35 min. Reconnected flow meter and after a couple minutes LN2 started flowing out again and froze the flow meter. Hoping it will thaw and work again. Until then the original exhaust pipe was reinstalled.
