US Patent 6,874,375

The Pitotless Nozzle is designed for taking precision flow rate measurements without a pitot. You won’t have to shut down in the middle of a test to change out a pitot because it got hit by a rock. Use it with the 2 ½” Hose Monster® in fire pump testing, fire flow testing or unidirectional flushing; or mount it directly on a hydrant, test header valve, or any fixed 2 ½” outlet.

Flow rate is determined by reading internal pressure of the nozzle. With no pitot in the stream, most debris will pass through without causing damage. The unique constant area reduction shape of the Pitotless Nozzle creates a steady laminar flow. Even when attached directly to a hydrant nozzle, the gauge needle is steady.

• No More Pitot Replacements
• Read flows from 48 GPM to 1607 GPM
• Four sizes - 1", 1 1/8", 1 3/4", 2"
• Color-coded for easy size identification
• FM Approved for flow rate accuracy
• Creates a laminar flow that eliminates turbulence and gauge needle bounce
• Anodized Aluminum
• Use with or without the Hose Monster™

If using the Pitotless Nozzle WITHOUT the Hose Monster.

The Pitotless Nozzle must be attached securely to a hydrant or other stationary device. The thrust created by high velocity water flow is dangerous to personnel and destructive to property. DO NOT attach the Pitotless Nozzle directly on the end of an unsecured hose. Clear water discharge path.

LIST OF “DO NOTS”

• Do not attach the Pitotless Nozzle to the end of a hose unless the Hose Monster is attached to it or unless it is permanently secured.
• Do not attach a hose to the male outlet end of the Pitotless Nozzle under any circumstance. The resulting backpressure will distort flow rate measurements.
• Do not over tighten the gauge or adapter into the brass gauge port. Always use a holdback.

Two spanner wrenches are needed to tighten/loosen the Pitotless Nozzle. A universal spanner wrench (WSPA101) used for hose connections and a special hole-type spanner wrench (WSPA104) used as a holdback on the body of the Pitotless Nozzle.
