The workstation is constructed of heavy-duty, welded steel. Industrial quality components are mounted and plumbed in a closed loop circuit to control the water flow between two tanks or the liquid level in one tank. The Level And Flow Process Control Learning System teaches two of the most common types of process control systems, flow and liquid level, and the basic concepts on which other systems are based. All components are connected to banana jacks on the control panel to allow students to measure signals and connect the devices in a wide variety of control configurations. Students will learn to calibrate, adjust, install, operate, and connect process control systems in industrial applications. The process control simulator includes a bench-top workstation, process control network, control panel, student learning materials for both theory and lab, and teachers guide.
This allows students to study a wide range of process control methods. The relay control includes manual input switches, control relays, solenoid valves, and float switches to perform automatic on/off liquid level control. Level And Flow Process Control Learning System offers 3 types of controllers: relay control, the standard, and two options: PID controller and PLC control. Manual valves are used to switch between the PID and on/off control methods. The PID controller option enables variable electronic control of either liquid level or flow and the PLC controller option enables both on/off and PID control of the system.

Level Control AND Regulation Study Unit makes it possible to analyse the behavior of a control loop where the controlled quantity is the water level in a tank. The unit can be had in two versions, where the control element consists of a pneumatic valve or a motorised electricvalve. Students can examine the effects of the different control parameters on the performance of the control chain and the stability of the system; furthermore, they can become familiar with the components commonly adopted in modern industrial applications, as the system is entirely made of industrial quality components. The behavior of the controlled quantity can be followed visually so that the students can grasp the basic concepts of control and regulation techniques in an intuitive manner.

This Level Control System is designed to allow numerous level control experiments to be performed within a typical laboratory session. This invention relates to an improved type of electronic liquid level control apparatus, yand more particularly toa relatively. A simple electronic type 'of controller which may be utilized to maintain substantially accurate liquid levels, within small liquid receiving chambers. A for use with very small liquid receiving chambers, such as -may be used 'in laboratory apparatus or pilot plants, or they are not adapted for use with extremely high pressure'equipment because of yinadequate packing glands or sealing means. Still other types of liquid level 'controllers are adapted to operate overa relatively wide range of level variations and are not sensitive to small changes ,in liquid' level. The unit enables students to investigate the effects of changing the parameters of the control algorithm and changes can be made to the process conditions by adjustment of the ow into the vessel. Many of the present-forms of liquid level ycontrollers are of a type which are not suitable.
