The simplest, most reliable and sufficiently accurate method of dosing bulk products is batch dosing by volume using measuring containers. The article considers a mathematical model of a volumetric dispenser. The combination of several methods of regulating the supply of bulk materials during batch dosing is ensured by building an accurate model of the drum dispenser.
