Proportioning Equipment introduces the foam concentrate into a flowing stream of water to produce a foam solution. There are many methods of proportioning, but fixed foam systems typically use balanced pressure proportioning equipment. All balanced pressure systems use a modified venturi device called a proportioner or ratio controller.

Proportioners are available in a variety of sizes and styles to match required flow ranges and pipe sizes. Each proportioner consists of a body, inlet nozzle, and metering orifice—all of which are corrosion-resistant brass.

Proportioners are UL listed and FM approved with certain foam concentrates and used in conjunction with bladder tanks and pump proportioning skids. Typical applications include flammable liquid storage tanks, loading racks, aircraft hangars, heliports, and anywhere flammable liquids are used, stored, processed or transported.
