<p>A method and device are disclosed for monitoring lacquer consumption per can (2) in a lacquer application unit (3). The device includes counter means (32, 33) providing can number data on the number of cans (2) being applied with lacquer in the application unit (3); a tank (8) for intermediate storage of lacquer; means (15') for feeding lacquer from a lacquer reservoir (14) to the tank (8) through an inlet pipe (15); and means (13) for feeding lacquer from the tank (8) to the application unit (3). Valve means (17) are provided in the inlet pipe (15) for intermittent movement between a closed position and an open position, in which lacquer is admitted into the tank (8). A flow meter (16) is arranged to provide flow rate data on the amount of lacquer flowing into the tank (8). The device also includes processing means (35) that, over a time period between two subsequent movements of the valve means (17) to one and only one of said positions, effects a calculation of the total amount of lacquer passing the flow meter (16) and, the total number of lacquer coated cans (2), to calculate a lacquer consumption value per can. <IMAGE></p> |
