Claim Text:
1. A device for measuring thickness in horizontal strip casting installations for casting strip or sections, the device comprising: a measuring device ( 5 ), where a liquid or pasty metal or steel melt enters a traveling mold ( 3 ) from a vessel ( 2 ), the vessel ( 2 ) receiving the melt from a reservoir ( 6 ), and the thickness of the liquid or pasty melt ( 13 ) is measured in the mold ( 3 ), wherein the measuring device ( 5 ) operates without contact by a laser and an optical sensor that are arranged so that the surface of the liquid or pasty melt ( 13 ) is monitored, whereby the thickness distribution over an entire width of the melt is measured, a measuring signal is generated based only on the measured thickness, and a control signal is generated based on the measuring signal in order to control a device for distributing the melt so that a mass flow of the melt from the vessel to the mold is exclusively controlled by controlling the mass flow of the melt from the reservoir to the vessel to counteract a thickness taper and waviness of the strip while the melt is monitored, wherein the mold is oriented based on the measured thickness distribution so as to counteract the thickness taper and waviness of the strip.
