A method and device are disclosed for monitoring lacquer consumption per can in a lacquer application unit. The device includes a counter providing can number data on the number of cans being applied with lacquer in the application unit; a tank for intermediate storage of lacquer; a lacquer feeder for feeding lacquer from a lacquer reservoir to the tank through an inlet pipe; and a lacquer feeder for feeding lacquer from the tank to the application unit. A valve is provided in the inlet pipe for intermittent movement between a closed position and an open position, in which lacquer is admitted into the tank. A flow meter is arranged to provide flow rate data on the amount of lacquer flowing into the tank. The device also includes a processor that, based on the flow rate data and the can number data, over a time period between two subsequent movements of the valve to one and only one of the positions, effects a calculation of the total amount of lacquer passing the flow meter during the time period and the total number of lacquer coated cans during the time period, to subsequently, by dividing the total amount by the total number, calculate a lacquer consumption value per can.

1. A method for monitoring the amount of fluid being applied to cans in an application unit, said unit being connected to a fluid reservoir via an intermediate storage tank, said tank having an inlet pipe connected to said reservoir and an outlet pipe connected to said application unit, valve means being arranged in said inlet pipe for movement between a closed position and an open position, said method comprising the steps of:intermittently moving said valve means from said closed to said open position, thereby admitting said fluid into said tank and raising a fluid surface therein from a lower level to an upper level; measuring an amount of said fluid entering said tank by means of a flow meter arranged in connection with said inlet pipe; counting a number of cans being applied with said fluid in said application unit; calculating a first value indicating the total amount of said fluid passing said flow meter during a time period between two subsequent movements of said fluid surface to one and only one of said levels; calculating a second value indicating the total number of cans being applied with said fluid during said time period; and calculating a fluid consumption value per can by dividing said first value with said second value.
