5.0 FLOW CHARACTERISTICS
The BLITZFIRE Portable Monitor is designed for maximum flows of 500 GPM (2000 LPM) and a maximum pressure of 175 PSI (12
BAR). Do not exceed these limits.
5.1 AUTOMATIC, FIXED, AND SELECTABLE FLOW NOZZLES
A variety of water or foam nozzles may be used with the BLITZFIRE Portable Monitor.
Automatic nozzles maintain a constant pressure by adjusting their opening to match the available flow. Consult the nozzle manufacturer
for maximum flow and pressure ratings. In all cases do not exceed 500 GPM (2000 LPM) and/or 175 PSI (12 BAR).
5.2 STACKED TIPS OR SMOOTH BORE NOZZLES
Table 5.2
5.3 STREAM STRAIGHTENERS
Stream quality, especially with smooth bore nozzles, is improved with the use of a stream straightener. A stream straightener is
integrated into the exit of the monitor.
5.4 USE WITH FOAM
The monitor may be used with various foam nozzles and foam solutions. Refer to fire service training for the proper use of foam.

WARNING
For Class B fires, lack of foam or interruption in the foam stream can cause a break in the foam
blanket and greatly increase the risk of injury or death. Follow procedures established by the AHJ
for the specific fuel and conditions.
WARNING
Improper use of foam or using the wrong type of foam can result in illness, injury, or damage to the
environment. Follow foam manufacturer’s instructions and fire service training as directed by the
AHJ.
WARNING
Use of compressed air foam (CAF) with portable monitors can cause sudden surges in nozzle
reaction force resulting in risk of injury or death from hose whipping or an out of control monitor.
Be prepared for sudden changes in nozzle reaction caused by:
• Slug loading (Loss of foam concentrate sends slugs of air and water into the nozzle)
• Sudden release of built-up pressure in the hose when opening a nozzle
