Abstract
An apparatus for the gravimetric dosing of flowable components, whereof at least one is a liquid, e.g. for producing mixtures, has a storage container and a weighing container for each component, together with a feed line connecting said container, as well as a weighing frame with a balance for all the weighing containers and a discharge line for each weighing container leading to a mixing device. Each discharge line contains a shutoff valve near the mixing device. The weighing containers are filled with the individual components up to a predetermined level and then each component is discharged from the weighing container into the mixing device in the subtraction process. This permits an accurate dosing of components with different physical characteristics and different flow behaviors, even in the case of high viscosity liquids.
