Abstract

A filter for an aqueous solution, such as urea, of a diesel vehicle selective catalytic reduction system, includes a housing provided with an inlet and with an outlet and, inside which, is arranged a filter element. Variations in volume associated with changes in phase of the aqueous solution are detected and a switch which switches upon changes in phase of the aqueous solution signals the variations in volume.
