Description

The Buckeye Model FAM – PO Ratio Flow Controller is aproportioning device designed to meter the correct amount of foam concentrate into the water stream over a wide range of flows and pressures. These units are used in conjunction with either a bladder tank or a foam pump proportioning system.The operating principle of the controller is based upon the use of a modified venturi. As thewater passes through the inlet jet, a reduction in pressure in the annular area is created. Thisreduction allows the metering of the foam concentrate into the water stream through the foam concentrate metering orifice.
