The RT 578 facilitates hands-on learning in the control of four controlled variables that are common in process engineering. A circuit with a graduated transparent reservoir is provided for flow, level and pressure control. Two drive possibilities are included, namely a variable speed pump and a pneumatic control valve. A disturbance variable can be generated by a valve at the tank outlet for level and pressure control. A valve in the tank head also allows investigation of level control with and without back pressure. A heating circuit is provided with a heater, a heat exchanger and a pump to control the temperature. The temperature can be controlled using the heater as an actuator, or by cooling water flow through the heat exchanger.
