Abstract
A proportioner apparatus for mixing together at least two fluids in controlled, preselected proportions, comprises first and second fluid inlet reservoirs, first and second fluid inlets coupled respectively for delivering fluids to the first and second reservoirs, first and second outlets coupled respectively with the reservoirs for receiving a flow of fluid therefrom, each said inlet having a control valve for controlling the flow of fluid therethrough in response to predetermined control signals, and each said reservoir having level sensor therein for producing the control signals in accordance with the level of fluid therein. A novel orifice-defining assembly is associated with at least one of the outlets for, together with the level of fluid in the associated reservoir, controlling the rate of flow of fluid through the outlet whereby any desired one of a plurality of different flow rates may be achieved by selection and placement in the outlet of a removable mounting assembly having a plate with an orifice of a size selected to achieve the desired flow rate. Preferably a stratification prevention arrangement is also employed to prevent stratification of fluids in the proportioner.
