Control of the amount of oil and the quality of oiling (uniformity of oil distribution over the surface) is carried out on the upper and lower sides of the rolled metal. Based on the results of the control, the system should provide information on the uniformity of the distribution of the oiling liquid over the surface of the rolled metal with an accuracy of +/-0.1 g/m². "1. Type of product – cold-rolled metal: 2. Strip thickness, mm: 0.25-4.0 3. Strip width, mm: 500-1850 4. Working speed, m/s: 0.5-6.0
