DEVICE FOR CONTROLLED METERING AND MIXING OF A PLURALITY OF ACTIVE LIQUID SUBSTANCES

摘要

The present invention relates to an automatic or semiautomatic device for the controlled metering and mixing of a plurality of active liquid substances for plants. Said device includes a means for selectively sampling said substances in corresponding containers and moreover includes a fluid transfer means and, finally, a means for metering, mixing, and diluting the sampled or transferred amounts of the liquid substance(s). Said device also includes a controlling and managing unit that controls the sampling and transferring means and is associated with measurement means and a means for controlling the flow of fluids within the valve-type device. Said device (1) is characterized in that the measurement means include a means (7), advantageous for sequential use, for measuring a basic volume of a sampled concentrated liquid substance, said volume needing to be mixed and/or diluted. Said measurement means moreover include a means (8) for continuously measuring the final volume of the metered solution obtained by diluting, after metering, the concentrated liquid substance or the mixture of concentrated liquid substances.
