Abstract

A method of determining a filling level of a product in a tank having a tank wall, the method comprising: generating and transmitting an electromagnetic first transmit signal; propagating the first transmit signal through a tank atmosphere towards a corner reflector formed by the surface of the product and the tank wall where the surface of the product meets the tank wall, the corner reflector being at a known horizontal distance from the radar level gauge system; receiving an electromagnetic first reflection signal resulting from reflection of the first transmit signal at the corner reflector; determining a measure indicative of a propagation direction of the first reflection signal; and determining the filling level based on the measure indicative of the propagation direction of the first reflection signal and the known horizontal distance between the radar level gauge system and the corner reflector.
