HIGH FLOW FOAM SYSTEM FOR FIRE FIGHTING APPLICATIONS

WIPO Patent Application WO2005021099

A3

A fire-fighting system in which multiple water discharge lines each have associated with them a foam concentrate delivery line where each of the foam concentrate delivery lines are supplied from a foam concentrate tank by way of a positive displacement pump having the capability of having its flow rate adjusted. Each of the water discharge lines includes a flow meter as do all of the foam concentrate delivery lines. The foam concentrate delivery lines also include a valve whose orifice size is electrically controlled. Associated with each of the foam concentrate delivery lines is a microprocessor-based line controller module that receives inputs from the flow meters in the water discharge lines and the flow meters in the foam concentrate delivery lines whereby the proportion of foam concentrate to water in the separate water discharge lines can be set at predetermined values. A main microprocessor-based controller is coupled to each of the several line controllers and the output of the main controller is used to adjust the output flow rate of the foam concentrate pump.
