Flow Control Demonstration Unit- Engineering Lab Training Systems Description and Specifications for Lab Tenders
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.
