The measuring apparatus consists of two physically different working measuring systems (22, 26) each with a sensor (24, 28). The sensors are fixed in a predetermined position with respect to the mold (10). The first measuring system (22) has a measuring precision of at least plus or minus 2 mm in a measuring region of at least 200 mm. The second measuring system (26) has a measuring precision of at least plus or minus 0.1 mm in a measuring region of at least 20 mm. Vertical continuous casting plant comprises a mold (10) with a moving floor (14) arranged on a sinking casting plate (16), a launder system (20) for transporting a metal melt from an oven into the mold, a measuring apparatus for determining a time-dependent metal melt level (N(t)), and a through-flow regulator (30) to control the metal supply in the mold depending on the difference of a prescribed theoretical value progression Nsoll(t) and the measured time-dependent metal melt level (N(t)).
