Computerized Flow Control Trainer
Product Code : EL-MAILE-10801
Quick Answer: The Computerized Flow Control Trainer is a closed-loop process control trainer that demonstrates industrial flow control using real control-engineering components. A centrifugal pump (250W, 150L/min, 7m head) delivers water from a 30L storage tank through a piping system, an electromagnetic flow sensor (0…6000L/h) and a Rota meter (0…1960L/h) measure the flow rate, and a state-of-the-art digital industrial controller drives a motorized control valve (Kvs 5,7m3/h) to regulate it, while a ball valve in the outlet line introduces defined disturbance variables. The controlled variable X and manipulating variable Y are plotted on an integrated 2-channel line recorder or tapped as analogue signals at switch-cabinet lab jacks for connecting external recording equipment such as an oscilloscope or flatbed plotter, giving students a practical, industry-realistic introduction to control-engineering fundamentals with a freely configurable P, I, D digital controller.
A pump delivers water from a storage tank through a piping system, and the flow rate is measured by an electromagnetic sensor, which permits further processing of the measured value by outputting a standardized current signal, while a Rota meter also indicates the flow rate directly. The controller used is a state-of-the-art digital industrial controller, and the actuator in the control loop is a control valve with electric motor operation; a ball valve in the outlet line enables defined disturbance variables to be generated. The controlled variable X and the manipulating variable Y are plotted directly on an integrated 2-channel line recorder, or alternatively the variables can be tapped as analogue signals at lab jacks on the switch cabinet, which enables external recording equipment, such as an oscilloscope or a flatbed plotter, to be connected.
