Abstract
A method of proportioning a finished foam at or near a hazard comprising proportioning and delivering a first finished foam to the hazard, determining if the first finished foam extinguishes or suppresses the hazard, if not, selecting an amount of a fluorinated additive, and proportioning a foam solution including the selected amount of the fluorinated additive to form a fluorinated finished foam. A foam injection system is also disclosed.
Claims15
A foam injection system, comprising:
- a first pump coupled with a foam supply;
- a second pump coupled with an additive supply;
- at least one of a water supply and a water pump that receives water from the water supply;
- and
- a flow controller comprising one or more processors and computer-readable instructions that when executed by the one or more processors, cause the one or more processors to:
- determine a first flow rate of foam outputted by the first pump;
- determine a second flow rate of water outputted by the at least one of the water supply and the water pump;
- identify a first target ratio of water and foam;
- control the first flow rate based on the second flow rate and the first target ratio;
- and
- control a third flow rate of additive outputted by the second pump based on the second flow rate and a second target ratio of water and additive.
