I have not the needed number of probes to take ALL the suggested measurements. At the moment the setup is:
pump -->Temp1-->chiller-->Temp2-->WB-->flowmeter-->valve-->res-->pump
Assuming losses to imperfect insulation being minor, the most efficient placement would be to insert temp3 after waterblock but before flowmeter. That would allow one to get deltaT across waterblock and across the pump.
Alternatively I can rig up a bunch of DOW sensors inline and measure everything. Not gonna be the specs that you want to hear though (0.5C accuracy and 0.125C res). I guess I could rig up some other solution with thermocouples but that is a road I prefer not to embark upon.
With my available thermistors I could plumb either a third probe into the cold loop as noted above or I can plumb a second probe into the hotside loop to measure delta T across the hotside block. I must remind you that at the moment I have 2 hotside loops that are separate and one has a pelt running at 12V and the other at 13.5. This undoubtedly complicates serious investigation of the hotside loop; if required I could merge that into a single loop with parallel chiller blocks and parallel radiators to simplify temperature collection.
