METHOD AND FILLING DEVICE FOR FILLING A TRANSPORT CONTAINER WITH A FLUID

In the case of a method for filling a transportation container (12) with a fluid, the fluid in a purification circuit (1) is conveyed multiple times through the purification installation (7), and by way of a contamination-measurement installation (15) a key contamination indicator of a fluid-specimen quantity in the purification circuit (1) is determined, wherein a filling procedure of the transportation container (12) with the fluid is terminated only once the key contamination indicator undershoots a first threshold value. The fluid-specimen quantity that is provided for determining the key contamination indicator may be diverted from the purification circuit (1), be infed to the contamination-measurement installation (15), and upon determining the key contamination indicator be returned to the purification circuit (1). In a container-purification step, a container-fluid quantity from the purification circuit (1) that has previously been introduced into the transportation container (12) may be again retrieved from the transportation container (12) and be returned to the purification circuit (1). A key contamination indicator of that container-fluid quantity that has been retrieved from the transportation container (12) may be determined by the contamination-measurement installation (15), and the filling procedure of the transportation container (12) with the fluid may be terminated only once the key contamination indicator undershoots a third threshold value.
