Foam monitors are high capacity jets, controlling horizontal and vertical flow, that can be used to deliver large quantities of foam accurately to the affected area in the shortest possible time and from a safe distance. Nozzles attached to foam monitors can also be adjusted to adapt the foam agent flow from fog or wide beam to jet or straight beam to increase the flexibility to the user. Monitors motion can be controlled automatically using water oscillators, electrically using joysticks, or manually using tiller bars or housewheels.
