May be these rhreads may be of some helo: thread391-251669 thread391-248129

Look for a low-boiling azeotrope with no environmental risks. In any case, condense and collect the condensate for safe disposal.

Is it possible to weigh the assembly and estimate the level based on the flud's density?

If the flowing fluid is incompressible, with p (rho) as density, a Pitot tube would measure total local pressure or stagnation pressure pstag=p+1/2pv2, while a static gage would measure p. The difference of the readings is the velocity head. The units in this equation can be Pa or N/m2.

Just a counterintuitive curiosity, the kinematic viscosities of gases can be greater than those of lube oils. http://www.engineeringtoolbox.com/dynamic-absolute-kinematic-viscosity-d_412.html

See Heat Exchanger Efficiency Article in Journal of Heat Transfer · September 2007

According to that equation, if hot water and steam have the same TH, for equal heat duties Q, and equal TL, one gets equal ΔS?

As I see it, and I may be mistaken, the thermal efficiency of a heat exchanger is generally expressed as the ratio of the actual heat transferred to the optimum heat transfer Qopt = UA (AMTD). Each case has a different Qopt. Us-w > 2 Uw-w AMTD for steam-to water: (131+60)/2 = 95.5 °c...

Would thread798-424587 be of help?

One way to get a quick estimate of the liquid heat up by pumping is by calculating the work done on the fluid: ∆t=∆P/(ρ×Cp) Using consistent units.
