The trainer is composed of:

1. An educational board with a pressurized vessel and a set of sensors and actuators for level, pressure, temperature and flow;
2. A control module, containing the interface circuits for the sensors and the actuators and the on/off, proportional, integral and derivative control circuits (pid).

With this system, the student will be able to study the following:

1. Study of the level, flow, pressure and temperature sensors
2. Study of the characteristics of the pump and of the motor pump
3. Study of the characteristics of the static process and of the time constants
4. On-off, p, pi, pd and pid closed loop control of the level
5. P, pi, pd and pid closed loop control of the flow
6. On-off, p, pi, pd and pid closed loop control of the temperature
7. On-off control of the level with the pressure sensor
