Abstract

The invention relates to a delivery unit (1) for extracting liquid additive from a tank (2) which delivery unit can be mounted on the tank (2) having a fill level sensor (3) for measuring the fill level of liquid additive in the tank (2) wherein the fill level sensor (3) is set up to emit waves into an emission region (4) of the tank (2) and the fill level can be measured by means of a propagation time measurement of the waves that are reflected by a liquid surface (5) and strike the fill level sensor (3) again and wherein the delivery unit (1) has at least a first reference surface (6) which extends at least partially into the emission region (4) and is at a first distance (7) from the fill level sensor (3) wherein the at least one first reference surface (6) is arranged on a separate calibration component (10) which is mounted on an outer side (11) of a housing (12) of the delivery unit.
