To improve large scale process cooling systems (300kW and 1MW) an online sensor for the thermophysical properties of the coolant is needed to improve the stability of outflow temperature. Here the fluid parameters influence the precision of the power balance at the heat exchanger. The remaining misfit is compensated with a classic PID-controller. A precise knowledge of coolants properties would decrease the fraction of PID and increase the validity of set point calculation. The task would be to develop the present design further to an integrated prototype and to validate the measurement principles (direct measurement, transient hot wire, 3Omega).

The complexity of the problem will be adjusted to the abilities of the student!
