A fluid control system suitable for controlling the volumetric rate of fluid flowing in a conduit. This system includes a chamber communicating with a conduit, a downstream and upstream wall are formed in the chamber and each has an opening in their lower ends to permit undisturbed flow of fluid therethrough at a predetermined level. An additional orifice is formed in the upstream wall above the first opening to permit fluid entry into the chamber when the fluid exceeds the predetermined level thereby flooding the chamber between the two walls & dissipating the velocity of the fluid so as to limit the volumetric rate of flow in the conduit.
