Figure 2-2: Hale CAFSPro Compressed Air Foam System
The Hale FoamLogix foam proportioning system uses a rugged Class 1 flow sensor
to measure water flowing out the foam capable discharge(s). The Hale FoamLogix
control unit has a computer chip that constantly compares the water flow and foam
concentrate flow rates to inject the proper amount of foam concentrate based on
the operator selected injection rate. The operator can select any foam concentrate
injection rate at the control unit from 0.1% to 10.0% dependent on fire ground
requirements. The control unit provides the operator with the water flow rate as
well as total water flowed, foam concentrate injection rate and total foam concen-
trate used.
