Without going into the full soap opera, the PSL chiller was replaced with the "original"
chiller.  This chiller was upgraded with the new vortex flow sensors.  A new calibration
factor for the flow sensor was entered into the chiller's memory bank and the bypass
valve was manipulated to give the right flow rate through the HPO laser heads and front
end laser.

    A log about the interlock will be submitted later once I've sorted out the messy
details.
