<p>An apparatus for automatically metering fluid substances, such as dyes and the like, comprises a metering cabinet in which metering valves for metering the substances are arranged above a collecting vessel placed on a balance. The valves are installed at the ends of respective withdrawal hosepipes coming from respective containers for the substances stored in a warehouse, or in a plurality of warehouses situated separate in space from the cabinet. Along the hosepipes, conveyor pumps are installed. The warehouse can also be arranged at lower levels than the metering valves. Under the collecting vessel, inside the metering cabinet, at least one dilution and/or mixing vessel is placed, from which the properly metered product is delivered to a feed unit arranged outside the cabinet. The operation of the metering valves is automatically controlled by means of a proper microprocessor-controlled apparatus as a function of the weighing data.</p> |
