This in-line active and reverse calculating mass balance blending system can maintain a chemical at desired control points, such as with respect to concentration, temperature, and/or pressure, while the output flow rate is changing dynamically to a point of use. A blending unit is configured to receive and blend at least two species and deliver a mixture at selected concentrations to points of use. A controller can be configured to determine a mass balance to maintain the concentrations in the mixture using information from metrology systems and a flow in an output to the at least one point of use. The controller also can be configured to maintain a concentration in the mixture within a concentration range by controlling flow rates to the blending unit.

The present disclosure relates to a method for preparing a coating material composition or a precursor thereof, the method including at least step (1), weighing out all required components into a suitable container by means of at least one metering valve when using a gravimetric metering system, the components that are weighed out into the container being mixed by means of at least one stirring body throughout step (1) and a continuous adaptation of the position of the at least one stirring body to the respective filling level within the container taking place throughout step (1), the respective filling level being predetermined by the amount and number of components that are weighed out into the container and the position of the at least one stirring body corresponding to the height of the stirring body within the container, calculated from the bottom of the container.
