Foam Proportioners Flashcards
The following apparatus mounted foam proportioning system provides the most accurate proportioning of foam concentrate at large flow rates
Variable flow variable rate direct injection systems
The following apparatus mounted foam proportioning system has a foam concentrate line connected to each fire pump discharge outlet
Bypass type balanced pressure proportioner
The following apparatus mounted foam proportioning system has the advantage of being maintained In a ready to pump condition an requiring no flushing after use
Variable flow demand type balanced pressure proportioning system
The following apparatus mounted foam proportioning system has the advantage of being able to simultaneously discharge foam from some outlets and plain water from others
Bypass type balanced pressure proportioners
The following apparatus mounted foam proportioning system has the advantage of being able to automatically adjust to changes in water flow when nozzles are either open or closed
Variable flow variable rate direct injection systems
Which of the following apparatus mounted foam proportioning system has the advantage of being able to have nozzles either above or below the pump with out affecting the foam proportioning
Variable flow variable rate direct injection system
The following foam generating system introduces compressed air into the foam solution prior to discharge into the hose line
High energy foam generating systems
The following foam proportioning systems consists of a small return water line connected from the discharge side of the pump back to the intake side of the pump
