A discharge element is arranged in communication with the chamber of the body member, the discharge element comprising a first discharge element 16 through which a first metered volume is dischargeable to a first part of the equipment and a second discharge element 18 through which a second metered volume is dischargeable to a second part of the equipment. ## Claims ### Claim 1 A metering system for metering liquid to be supplied to equipment which utilizes the liquid to generate a predetermined product, the metering system including a body member which defines a chamber therein, the body member being mountable in a predetermined position relative to the equipment and liquid to be metered being received in the chamber; and a discharge means in communication with the chamber of the body member, the discharge means comprising a first discharge element through which a first metered volume is dischargeable to a first part of the equipment and a second discharge element through which a second metered volume is dischargeable to a second part of the equipment. ### Claim 2 (depends on 1) The system as claimed in claim 1 which includes a control means for controlling discharge of the liquid from the discharge means. ### Claim 3 (depends on 2) The system as claimed in claim 2 in which the body member comprises a tray-like element which is displaceably mountable on the equipment. ### Claim 4 (depends on 3) The system as claimed in claim 3 in which the tray-like element includes a pivot-axis defining means via which the tray-like element is mounted on the equipment to be pivotally displaceable relative to the equipment. ### Claim 5 (depends on 4) The system as claimed in claim 4 in which the control means comprises a counterweight mounted on the tray-like element on one side of the pivot-axis defining means with the chamber being arranged on an opposed side of the pivot-axis defining means. ### Claim 6 (depends on 1) The metering system as claimed in claim 1 in which a partition-like part extends at least partially into the chamber to facilitate the metered discharge of the liquid through the discharge elements. ### Claim 7 (depends on 6) The metering system as claimed in claim 6 in which the first discharge element is arranged proximate a first end of the chamber and the second discharge element is arranged proximate an opposed, second end of the chamber with the partition-like part being mounted closer to the second discharge element. ### Claim 8 (depends on 7) The metering system as claimed in claim 7 in which a transverse, operatively vertical cross-section of the chamber decreases from the first discharge element to the second discharge element such that less liquid is discharged through the second discharge element than through the first discharge element. ### Claim 9 (depends on 6) The metering system as claimed in claim 6 in which the partition-like part extends fully into the chamber to define two compartments in the chamber with a first compartment being larger than a second compartment, and the first discharge element being associated with the first compartment and the second discharge element being associated with the second compartment. ### Claim 10 (depends on 1) The metering system as claimed in claim 1 which includes a supply means for supplying controlled supply of liquid to the chamber. ### Claim 11 (depends on 10) The metering system as claimed in claim 10 in which the supply means comprises a drip-feed device for supplying liquid at a predetermined rate to the chamber. ### Claim 12 (depends on 11) The metering system as claimed in claim 11 in the supply means includes a pressure control device for controlling the pressure of the liquid supplied to the drip-feed device.
