Hydrant Flow and Pressure Testing Kits
Note: Gauges supplied with our Test Kits are quality Liquid Filled Gauges but do not come from any manufacturer with individual certification. Certification insures accuracy and is necessary for certain types of testing. Certification is normally done on an annual basis. Certified Pressure gauge calibration is a process of comparing a gauge in at least 5 test points over the span to a known certified and traceable pressure measuring device. We can test and certify gauges with a calibration sticker and a N.I.S.T. (National Institute of Standards and Technology) calibration document for an additional charge of $39.50 each Gauge.

H-CL series Clamp on Hydrant Flow Liquid Filled Psi GPM Dual Read Gauge with Case. Will fit any 2-1/2 NST hydrant nozzle opening, performs a dynamic or kinetic test.

Dual read NNI Flow Gauge features a 4" Dial liquid filled gauge that shows both psi and gallons per minute designed to measue GPM flow for size 2½" only with 0.9 coefficient. Choice of Gauges in 3 ranges
  • 60Psi/1300 GPM
  • 100Psi/1680 GPM or
  • 160Psi/2120 GPM

It works with any thread pattern as it attaches to the hose nozzle via a thumb screw and clamp. To operate, you need to remove the 2½" hydrant nozzle cap. Clean the thread, 0pen hydrant to flush any debris from the barrel. Shut down the hydrant. Clamp the unit on the top of the nozzle thread with the blade parallel to flow direction. Select a thread, then tighten thumb screw to securely hold assembly on nozzle. Open hydrant fully. Purge the air from the bleeder by turning counterclockwise. After water flows from bleeder, retighten. Read pressure in pounds on inner ring, gallons per minute from outer ring.
