TCSY chiller water level

Attached is a rough trend of the amount of water we have added to the TCSY chiller over the last week in order to keep it "topped off".  There is ~kinda a downward trend, which may indicate we are finally getting to the point where the system is "full".  Recall, Wed Sept 28th the system ran dry due to a leak at the chiller.  At that time the chiller was refilled with ~5L of water.  We have since added another 5L of water (~300mL at a time over the last week).  The reservoir holds 7.2L and the piping probably takes a few more L so, maybe we are still clearing out air leaks in the whole stsyem...

We'll just slowly filling and watching for another few days and replot.
