Abstract

The invention relates to a feed unit (1) for feeding a liquid additive from a tank (2) which feed unit (1) can be mounted in the tank (2) having a filling level sensor (3) which can emit and receive waves which are reflected back to the filling level sensor (3) at a surface (4) of liquid in the tank (2) with the result that a filling level measurement can be carried out by measuring the transit time of the waves wherein the feed unit (1) has at least one additional sensor means (5) by means of which it is possible to determine whether there is frozen additive in the tank (2).
