An arrangement for measuring a level of a surface (4) of a filling product (5) in a receptacle (6) comprises a radar level transmitter (1) arranged remote from a measuring location above the filling product (5) and having an antenna (2) for directed sending and receiving of microwaves (3) and a microwave redirection means (7) for transmitting onto the surface (4) of the filling product (5) microwaves (3) sent from said antenna (2) and transmitting back to said antenna (2) microwaves reflected from the surface (4) of the filling product (5). To reduce installation and adjustment efforts, the microwave redirection means (7) has a first antenna (8) arranged at the measuring location above the filling product (5), a second antenna (9) directed to the antenna (2) of the radar level transmitter (1) and a short distance waveguide (10) between the first antenna (8) and the second antenna (9).
