Check whether both LHe liquefiers are producing with a rate of ~4 L/hr.
Check when the Liquefiers are going to be
full using
FULL (use

),
and notify the Target Expert with the time estimate (communicate this information to the Target Expert).
Check the total consumption rate (Magnet return flow + Separator return flow + Main return flow), and estimate how long the magnet LHe will take to get to 0%
(communicate this information to the Target Expert)
