METERING SYSTEM FOR A PLANT CULTIVATION APPARATUS

摘要

In accordance with a first aspect of the present invention there is a metering system (10) comprising at least one fluid reservoir (14) for holding fluid; at least one measuring chamber 16 in fluid communication with the fluid reservoir (14) by way of an inlet valve (26), each measuring chamber (16) able to store a predetermined amount of fluid and an outlet valve (28) provided therein; and a controller (42) operably connected to each inlet valve (26) and outlet valve (28). Only when the controller (42) operates to set an inlet valve (26) to an open position is fluid able to freely flow from at least one fluid reservoir (14) to fill its associated measuring chamber (16). Only when the controller (42) operates to set an outlet valve (28) to its open position is the predetermined amount of fluid stored in the measuring chamber (16) able to be delivered to a predefined location.
