Fire Flow Test Kit

  • Combines the most common flow testing tools into a single kit including a pitot gauge and two blades, 3 test caps, 2 pressure gauges, and a hydrant flow nozzle
  • Ideal for fire hydrants, fire hose, and other water-flowing equipment
  • Ships standard with a bleeder valve designed to protect pressure gauges against damage

Why choose this pitot gauge kit for flow testing?

This all-around test kit contains the tools you need for flow tests in a light, compact carrying case. Every kit contains:

  • Two 2-1/2 in. Liquid Filled gauges with 1% full-scale accuracy with quick disconnect fittings
  • Three test caps machined from solid brass (3/4 in., 1-1/2 in., and 2-1/2 in. NST x 1/4 in. NPT)
  • One stream-straightening fire hydrant flow nozzle
  • One quick-disconnect double-ball-valve-bleeder
  • One hex-shaped pitot gauge handles
  • Two standard pitot blades
  • A large carrying case from Plano (19 in. x 14-1/2 in. x 8 in. outer case dimensions) — a world-famous manufacturer of hard-shell cases for the outdoors
  • A 43-1/3 in. ft. roll of PTFE thread seal tape

Which dial ranges should I choose?

The analogue gauges in this flow test kit is available in multiple dial ranges. To prolong your gauge’s life, choose a range that places your expected pressures at the center of the dial or in the mid-range. For example, for testing outlets with 30 PSI choose a 0-60 PSI gauge range or for testing outlets with 50 PSI choose a 100 PSI gauge range.

Dial Ranges Major #'d Graduations Minor Graduations Smallest Graduations
-30-0-300 PSI 50 10 5
-30-0-200 PSI 20 10 2
-30-0-100 PSI 20 10 2
0-30 PSI 5 1 5
0-60 PSI 10 5 1
0-100 PSI 10 10 1
0-160 PSI 20 10 2
0-200 PSI 20 10 2
0-300 PSI 50 10 5

What do I do with these readings?

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). 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 the blow linked below.
