ELECTRONIC DOSING DEVICE OF LIQUIDS' SMALL QUANTITIES

摘要

The electronic dozer of a liquids small quantities is designed for transport and dosing liquids into one and/or more mixing areas from several tanks. The basis of the dozer rests in the fact that it consists of tanks (6) filled with dozed liquids with a capillary inlet piping (9) discharged into a totalling element (1) and a programmable controlling unit (7) controlling three-way electromagnetic valves (5) connected with the areas above the dosed liquids in the tanks (6), while the space above the level of a selected dozed liquid is connected with the source (3) of a constant pressure of the gas through a distribution piping system (8). The dozer can be used primarily where there is a lack of direct access to the mixing elements and liquids are necessary to be dozed in closed separate spaces, and also if it is necessary to programme the dozing of liquids due to a line batching.<IMAGE>
