A method and apparatus is disclosed for use in weighing products having circular or oval footprint or an outwardly projecting flange. A conveyor having a pair of parallel conveyor elements arranged to underengage the footprint or flange only adjacent the periphery thereof transports the products one at a time across a weigh pan or scale device, whose length in the direction of conveyor movement is selected as the lowest value required to achieve a desired settle time for the weigh pan. Preferably, the length of the weigh pan is chosen to be essentially equal to the diameter of products to be weighed.
