DOSAGE FUNCTIONS
Finishing of the dosage when reaching the target weight is managed as follows:

Single product dosage (load), (manually and automatically controlled).
Configuration for managing of one dosage system of one product. Application with partition of products with equal weight, filling of hopper or extracting of accurate quantities from a silo, supporting the operator with manual dosage.
Single product dosage (unload).
Configuration for managing of one dosage system of one product. Application with partition of products with equal weight or extracting of accurate quantities from a silo, with management control for refilling the silo.
Multi product dosage (load and unload).
Configuration for managing of one dosage system of several products. For mixing of products through recipe, with management control for mixers, burners or vibrators, using switching contacts destinated for this purpose.

LOAD: by weighing of the container to be filled; the weight increases until the set target weight is reached

UNLOAD: by weighing of the silo from which that product is to be extracted; the weight decreases until the set target weight is reached
