Abstract
The invention relates to a method for controlling a flow generator () in a tank () configured for housing a liquid comprising solid matter, the flow generator () comprising an impeller and being located at a height (h-mixer) in the tank () and the tank () having a predetermined maximum filling height (h-max), wherein the flow generator () is configured to be operated at a variable operational speed (n) and the demand of operational speed (n-demand) is dependent on the present liquid level height (h-present) in the tank (), wherein a max operational speed (n-max) of the flow generator () is the operational speed required when the liquid level in the tank () is equal to the maximum filling height (h-max), the present operational speed (n-present) being set equal to the demand of operational speed (n-demand) of the flow generator () that is determined using the formula:
