A studio-based process control course combines lectures, discussions, simulation exercises and
experiments in a single classroom. In this paper we present a chemical process control experiment
developed specifically for a studio-based course. The experiment is a simple mixing process involving
fresh water and a salt solution. The objective of the experiment is to regulate three measured process
variables (level, temperature and conductivity) at desired setpoint values, by manipulating three input
variables (freshwater flow rate, concentrated salt solution flow rate and heater power) via feedback
control. The experiment is described in detail, and its incorporation into undergraduate and graduate
control courses are described.
