Abstract
A method of determining a filling level of a product contained in a tank, the method comprising the steps of: a) transmitting an electromagnetic probing signal towards a target area of a surface of the product; b) receiving a reflected probing signal being a reflection of the electromagnetic probing signal at the surface; c) determining a parameter value indicative of an amplitude of the reflected probing signal; if the parameter value is indicative of an amplitude larger than a predetermined threshold value: d) transmitting an electromagnetic measuring signal towards the target area of the surface; e) receiving a return signal being a reflection of the electromagnetic measuring signal at the surface; and f) determining the filling level based on a time relation between the electromagnetic measuring signal and the return signal.
