Fire Flow Testing with the Hose Monster means that property damage, inaccurate and inconsistent readings go away. The Hose Monster cancels the thrust and is UL and FM Approved for accuracy.

The Hose Monster, in 4" and 4 1/2" sizes, uses a precision machined internal orifice plate to measure flow rates. There is no pitot to become damaged by rocks and flushing debris. This makes it an excellent device for flow testing large capacity systems and unidirectional flushing.
