The Inspector Complete Flow Test Kit redirects flows, straightens streams, and delivers high-accuracy readings for professional results. Measure flows at fire hydrants, fire hoses, and nearly anything that discharges water with a kit that includes:
- One brass test cap with a 2-1/2″ NST inlet and a 1/4″ NPT outlet
- A pitot gauge handle with two blades
- Two certified 3-1/2″ analog pressure gauges in any of seven dial ranges
- A portable carrying case from Plano—a world-famous manufacturer of hard-shell cases for the outdoors
- A 43-1/3″ ft. roll of PFTE thread seal tape
This kit is ideal for contractors who need certifiably precise, easy-to-view measurements of water flow from a wide range of outlets. Upgrading to the Digital Complete Kit adds two digital pressure gauges from Ashcroft—a world-leading manufacturer of pressure and temperature instruments. Take a look at our other flow test kits if you:
- Conduct water flow tests on a 3/4″, 1-1/2″, or 2-1/2″ outlets without the use of a fire hydrant flow elbow or digital gauges (Inspector Starter Kit)
- Usually test 2-1/2″ nozzles on fire hydrants and other 2-1/2″ MNST outlets (Inspector Hydrant Kit)
- Need all of the above, digital gauges, and a fire pump tachometer (Inspector Fire Pump Team Kit)
The Inspector Complete Kit maximizes accuracy for users and minimizes inconvenience for nearby pedestrians and vehicles. This kit is ideal for two contractors working in tandem: one can use a test cap and gauge to measure static pressure while another takes pitot gauge readings from an open hydrant
Tools inside each kit make it simple to measure the flow rate at a 2-1/2″ fire hydrant outlet:
- A 45-degree hydrant flow elbow diverts water away from passing cars or vegetation
- The fire hydrant flow nozzle straightens the stream, allowing for more precise readings
- An inspector places the pitot gauge in the path of flow and takes readings from the 3-1/2″, NIST-certified gauge
The Inspector Complete kit also features a ball-valve bleeder that can be used with the 3/4″, 1-1/2″, or 2-1/2″ NST test caps. Combining these components with a pressure gauge allows for measurements of static pressure at a variety of orifices while protecting gauges against excess pressure.
Every one of these flow test kits includes two Ashcroft 1009AW pressure gauges, which boast:
- Large 3-1/2″ dials
- 1% full-scale accuracy
- Stainless steel bodies and thread connections
- A dust-tight and water-resistant enclosure
- Shock-and-vibration-resistant PowerFlex™ technology
- A “zero box” that allows users to see when the gauge’s baseline pressure is in error
- Vibration-dampening internal components
Upgrade to the Digital Complete Kit and recieve two additional Ashcroft DG25 pressure gauges. These gauges are twice as accurate across their entire span—0 to 300 PSI—and protected by a weatherproof enclosure. These gauges:
- Can be used to recalibrate analog gauges in compliance with NFPA 25
- Simplify fire protection math by switching between nine different units of measurement
- Provide legible readings with digits measuring roughly 1/2″ tall
- Keep minimum and maximum results in memory for later use
All gauges included with these kits are NIST (National Institute of Standards and Technology) traceable. They include documentation explaining when and how the gauge was calibrated, allowing inspectors to conduct tests for government agencies and other entities with rigorous qualifications.

Each gauge provided with this flow test kit is available in one of eight dial ranges. To prolong your gauge’s life, use the table below to choose a range that places your expected pressures at the center of the dial or in the mid-range. For example, inspectors testing outlets with 30 PSI of pressure should choose a 0-60 PSI gauge—or a 100 PSI gauge for 50 PSI test pressures. This table also provides each range’s major and minor graduations (the large and small tick marks along the dial’s face).
|Dial Ranges||Center of Dial||Mid-Range||Major #’d Graduations||Minor Graduations||Smallest Graduations|
Pitot gauges provide pressure readings in pounds per square inch (PSI). These readings can be used to estimate how fast water flows, in gallons per minute (GPM), using formulas or a pitot gauge theoretical discharge conversion table (like the one included on each hydrant flow nozzle). Used to convert PSI readings to GPM.
Conversion accuracy depends on an accurate measurement of outlet size and the nozzle or outlet coefficient. For more on how and why to convert PSI to GPM in pitot tests, read QRFS’s “Pitot Gauges: How Do I Calculate the PSI to GPM Conversion?”
