Starting on 8/13 when we had the ESR glitch, the Helium level probe on the 500 Liter  stated acting up and has been reading noisey ever since. I looked back at the data and found that while still controlling at setpoint the supply valve has been more open since then. I went down to Hall B just now and changed the AMI135 Helium Level Controller from update to sample and back to update. 
The indicated level jumped to 80% with much less noise. It appears we have been overfilling the dewar since that event. The supply valve EV8210 is now closing and supply flow  to the hall has dropped by an indicated 1g/s
