A method for continuously supplying a metering device with different batches of one and the same liquid medium, in which method a new batch is supplied to the metering device after the metering of a first batch, wherein a medium of the new batch is progressively added to a medium of the first batch with the aid of a control during such a batch change, wherein the medium of the new batch is progressively added to the medium of the first batch by gradually increasing a volume of the medium of the new batch supplied to the metering device while simultaneously gradually reducing a volume of the medium of the first batch supplied to the metering device.
An apparatus for carrying out a method for continuously supplying a metering device with different batches of one and the same liquid medium, in which method a new batch is supplied to the metering device after the metering of a first batch, wherein a medium of the new batch is progressively added to a medium of the first batch with the aid of a control during such a batch change, the apparatus having a first and a second container and a first and a second pump, with which pumps medium can be supplied to the metering device via a common line, and having the control that is configured and adapted to control the two pumps such that a medium from the second container is progressively added to a medium from the first container, wherein the medium of the new batch is progressively added to the medium of the first batch by gradually increasing a volume of the medium of the new batch supplied to the metering device while simultaneously gradually reducing a volume of the medium of the first batch supplied to the metering device.
