The core of the DCM is composed by a set of pumps, one for each product
managed by the dosing machine, whose flow is continuously metered, controlled
and automatically adjusted, in order to perform a very precise dosing, in terms
of quantity and proportion of one products with the others. The required
products are dosed either with a continuous flow or with pre-set quantities in a
given interval of time.
All dosing operations are managed by a SATE multitasking industrial
computer that controls all machine functions, while executes a continuous check
of the operations as well as a diagnostics routine. Dosing instructions can be
imparted either by means of its keyboard or through a PC dedicated to the
management, recording and remote control of dosing operations. The computer
stores the recipes and controls the dosing operations according to the selected
recipe.
The
dosing machines "DCM" utilize inverter driven pumps which also have a
suction function; this eliminates many restrictions in the positioning of the
chemical tanks, i. e. oblige the positioning of the tanks on a structure over
the dosing station.
