The wide range proportioner accurately proportions foam concentrate into a water stream over a wide range of system flow rates and is configured to proportion foam concentrate at a 3% ratio. Wide range proportioners are an integral part of an approved foam system. In addition to the wide range proportioner, the main components of the approved foam system are specific foam concentrate(s), a foam storage tank, a concentrate control valve and foam discharge devices.
