The level on an RP type rad should not be any higher than the bottom of the curved section viewable through the cap. Secondly the overflow pipe should be clear. If both these are OK then there's no reason why anti-freeze mixture coolant cannot be used and the cap/rad shell interface sealed with a bit of clear silicone.
Personally I wouldn't bother with a calorimeter. It's just something else to worry about. If your cooling system is in good order then overheating shouldn't really be a problem.
I was afraid someone would say that! My approach up to now has always been to put in as much (water) as possible & let it self-level. Post-rebuild my cooling system should be in much better shape, but in the Alps it was always a question of when we boil rather than 'if'. Under these circs by the way I wouldn't trust my Wilmot Breeden calorimeter nearly as far as I could throw it!
