A weight-based, multiple filler filling machine has a simplified wiring arrangement. The filling machine fills a plurality of bottles with a predetermined amount in weight of an article through associated ones of a plurality of valves. The weight of the article placed in each of the bottles is measured by a load cell. An arithmetic unit is mounted on the surface of or inside each load cell for determining the weight level of the article as measured by that load cell and controlling the associated valve in accordance with the determined weight level.
