Row of nozzles with overlapping area at direction of moving hot plate is usually used. Homogeneity of descaling is very important parameter for final quality of the rolled plate. Paper discusses about measurements of impact footprint for single nozzle as well as for two overlapping nozzles. Two different methods were used in measurements. The first method measures impact forces in the free stream. The second method measures impact forces of water stream penetrating through the forming water layer on a test plate. Size of pressure sensor also influences the measurement data. Different dimensions of sensors were used. Measurement data were recalculated by inverse task to so called zero size sensor. Raw measured data as well as sharpened data are presented. The overlapping area is also discussed in this paper.
