Level loops present a challenge to process control because control objectives vary, from tight level control in reactors, to averaging level control in surge tanks. The Level Wizard was developed to guide engineers through choosing and implementing the best level loop control strategy, whatever the performance requirement. The Level Wizard: identifies the goals for the level loop; chooses the level control strategy that matches the plant’s goals; finds the best P, PI or PID parameters to meet those goals; and provides built-in user guidance. The Level Wizard provides a quick payback, according to the vendor, by: forcing the controls to adhere to the operational objectives, maximizing profits; maximizing surge usage for smoother response to upsets, keeping critical quality variables on target; and producing better and more consistent quality, safer operations and increased throughput.
