• What homogeneous temperature are we trying to achieve? [so that we know what temperature the sensors have to withstand]

- change in temperature less than 2K across tank [nearly isothermic] 

• Sensors:
• Static 
• Floating around 

Would a moving sensor affect the thermodynamics/temperature of the liquid?

• Is cost an important factor to the sensor?
