Thank you Brian,

Yes, due to the incident with beam tuning the operating conditions of 
the SVT have been revised.

The flow range on this sensor was not right for the cooling system from 
the very beginning.

According to Nathan V450 has the following conversion: V=A*12.5/2^31.

and the temperature formula: T=V*15.2905 - 25.5352

I'll check with Bob what's available. The new chiller has adequate 
cooling capacity for current conditions and the bath temperature is 
close to the inlet coolant temperature.
