Automatic precision control of high-speed filling and emptying operations, such as those in which a liquid is admitted into or discharged from a batch, is provided by a combination of a weighing system and associated electronic digital circuitry which regulates these operations in accordance with changes in instantaneous batch weight relative to stored information concerning initial weight and which further both reduces or "dribbles" the rate at which these operations proceed just prior to their completions and anticipates and accounts for so-called "in-flight" amounts of material remaining temporarily in transit.
