Select Control - Describe the Image
Thread Content
Hello everyone, could you please provide a brief description of this control loop? Thank you. Is it such that when the liquid level is low, the valve is controlled based on the liquid level, while if the liquid level is not at the low limit, the flow control valve is used? Is it this logic?
View: NOTES 4 and NOTE 2 indicate that there should be a description.

Temperature is used for cascade control of LLS flow, while flow control adjusts the size of the regulating valve in LLC (it’s a bit complicated, and there is significant delay in actual operation). LIC and FIC adjust the opening degree of their output valves to select the lower value.
