Level Control - Gap Simulation 2103

Model Description

The TSC Sim 2103 – Gap Level Control Simulation shows a vertical open top vessel being fed with a supply of water. The water exits the vessel through a single line with a valve controlling the flow.

The level of water in the vessel is controlled by a gap level controller directly controlling the position of the valve on the liquid exit stream. The gap controller allows the vessel to fill up to a set level before allow the vessel to empty down to another set level, before beginning to fill again.

The feed to the vessel can be varied by introducing a second flow of liquid to test the effect on the level control system.

Disturbances can be added to the upstream and downstream pressures of the system to allow realistic learning on how the control method responds to the type of disturbances found on a real plant.

The P&ID settings of the controller can be altered to improve the tuning of the controller for the various conditions that can be created.

The simulation includes exercise’s based around the tuning of the level control system.
