US 2024/0369248 A1 · CONTROLLER AND METHOD FOR MANAGING A FLOW UNIT

Abstract

There is described a controller and method for managing a flow unit. A measured full flow corresponding to a full open position of a flow control element of the flow unit is detected. A calibration nominal is established based on the measured full flow, and calibration relative flows are calculated based on the calibration nominal and calibration measured flows corresponding to calibration positions of the flow control element. Subsequent to calibration, an operation measured flow of the flow unit and an operation position of the flow control element are detected. A dynamic nominal is determined based on the operation measured flow and a particular calibration relative flow corresponding to the operation position of the flow control element. The operation position of the flow control element is controlled based on the operation measured flow and the dynamic nominal.
