Flow Control Demonstration Unit- Engineering Lab Training Systems

Technical Description This training system provides a comprehensive experimental introduction to the fundamentals of process control using an example of flow control. All components are clearly laid out on a vertical front panel. The large-format process diagram provides an aid to understanding. A pump transfers water from a storage tank into the piping system. The flow is measured by an electronic paddle-wheel flowmeter. The transparent variable-area flowmeter enables the control process to be observed very clearly. The controller used is a state-of-the-art digital industrial controller. The actuator in the control loop is an electric control valve. A ball valve in the pipe system enables defined disturbance variables to be generated. The controlled variable X and the manipulating variable Y can be tapped as analogue signals at lab jacks. This enables external recording equipment, such as a plotter or an oscilloscope, to be connected.   An instrumentation and control software with interface module (USB) is available as an accessory. This enables the key process variables to be represented, and control functions executed.   The well-structured instructional material outlines the technological fundamentals and provides a step-by-step guide through the experiments.
