Why choose this flow test kit?
This comprehensive fire pump test kit gives professional inspection and testing teams the power to test fire pumps, fire hydrants, fire hoses, and other components in water-based systems. Redirect flows, straighten streams, and measure a pump’s revolutions per minute (RPM) with:
- One CDT-HD2000 contact and non-contact digital tachometer from Checkline
- Two 3-1/2 in. Ashcroft 1009AW gauges with 1% full-scale accuracy with quick disconnect fittings
- Two Ashcroft DG25 digital gauges with 0.5% accuracy with quick disconnect fittings
- NIST calibration certificates for all measuring instruments
- 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)
- A 45-degree fire hydrant flow elbow
- One stream-straightening fire hydrant flow nozzle
- One quick-disconnect double-ball-valve-bleeder
- Two hex-shaped pitot gauge handles
- Three pitot blades: one standard straight blade and two ultra-thin (straight and notched)
- A large carrying case from Plano (21-3/4 in. x 17-1/4 in. x 9 in. outer case dimensions) — a world-famous manufacturer of hard-shell cases for the outdoors
- Spare gaskets
- A 43-1/3 in. ft. roll of PTFE thread seal tape
This kit is ideal for an inspect team that needs certifiably precise measurements in critical inspection, testing, and monitoring (ITM) tasks.
How does this fire pump test kit help in fire pump ITM?
Each of these flow test kits includes a digital tachometer from Electromatic Equipment Company, a corporation with more than 60 years’ experience in developing industrial measuring instruments. Their Checkline-brand CDT-2000HD tachometer allows users to measure the RPMs of a fire pump’s motor with direct contact or from as far as 24″ away. These instruments are accurate to .02% (up to 0.01 RPM) while offering:
- A measurement range from 1-99,999 RPM
- A traceable calibration certificate
- One large 6 in. wheel for contact-based measurements
- An LED-based non-contact mode that measures RPM at a distance with reflective tape (included)
- Units of measurement like RPM, feet/min, meters/min, and inches/min
- Memory for last, maximum, minimum, and average measurements
This kit’s tachometer may be used in installation and performance evaluation tests of fire pumps. Under NFPA 20 and NFPA 25, inspectors flow water through the pump at a variety of rates—and measure RPM—to determine if a pump remains fully operational.
How does this fire pump test kit help in fire flow testing?
During fire pump and fire hydrant tests, the Fire Pump Team Flow Test Kit maximizes accuracy for users and minimizes inconvenience for nearby pedestrians and vehicles. This kit is ideal for several 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 particularly 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 gauges
The Inspector Fire Pump Team 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.
This kit includes two Ashcroft 1009AW analog pressure gauges with NIST Traceable Certifications, which boast:
- Large 3-1/2 in. 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
This kit also includes two additional Ashcroft DG25 pressure gauges with NIST Traceable Certifications. 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 in. tall
- Keep minimum and maximum results in memory for later use
NIST (National Institute of Standards and Technology) traceable certificates will include documentation explaining when and how the gauge was calibrated, allowing inspectors to conduct tests for government agencies and other entities with rigorous qualifications.
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|
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.
