monitors both the foam concentrate and water pressures.
6. Ratio controller - ANSWER A device required for each foam outlet to
proportion the correct amount of foam concentrate into the water stream
over a wide range of flows and with minimal pressure loss.

mechanically mixes foam concentrate with water?

combustible fires?
10.Compressed air foam system (CAFS) - ANSWER What type of foam
system uses less water, has faster- acting fire suppression, and has longer
stream reach than other foam systems?

hazardous vapor suppression liquids and foaming agents intended to be
added to the water.

amount of foam concentrate into a stream of water flowing from a discharge.

foam concentrate directly into the fire apparatus water tank, thereby mixing
a large amount of foam at one time.
