Abstract

The invention relates to a catalyst feeding system fortank containing solid catalyst mixed with a carrier fluid. The tank system comprises a cylinder tank and a float (1) slidable in the cylindertank, and the catalyst mixture is fed into and dosed out of the cylinder tank on one side of the float. The cylinder tank is provided with a radar level gauge (8) for determining the position of the float (1) in the cylindertank. By means of the radar level gauge, the position of the float and thus the dosing of the catalyst can be measured reliably.
