Fire Hydrant Flow Testing Options
Using Dual Pressure Senders
With a second Pressure Sender you can enable the included flow calc mode and use it on the flow hydrant. The display will calc flow using standard NFPA 291 formulas and show PSI & GPM.
Step 1 -
Attach Pressure Sender to hydrant with test cap. Turn it on and open valve.
Benefits
-
Save time - a single person can conduct a flow test
-
Save water - user alert when 25% pressure drop is reached shortening test
-
1 button recording - easy to snapshot static pressure at beginning of test and residual pressure while test hydrant is flowing
-
No flow chart needed
-
More accurate simultaneous recording
-
Track total GPM used during test
What it looks like
Node 1 on left in standard pressure only mode.
Node 2 on right with flow calc mode enabled.
Live display with pressure alert
Test records display
Session stats auto calculated
Step 2 -
Attach Pressure Sender with flow calc enabled to diffuser gauge port. Turn it on and flow hydrant.
Using Triple Pressure Senders
With a third Pressure Sender you have options. You can enable flow calc mode as needed. The display will calc flow using standard NFPA 291 formulas and show PSI & GPM.
Great for large systems, teams conducting multiple flow tests, utilities and AHJ's.
Step 1 -
Attach Pressure Sender to hydrants with test cap. Turn them on and open valves.
Benefits
-
Save time - Have two test hydrants for every flow
-
Save water - user alert when 25% pressure drop is reached shortening test
-
1 button recording - easy to snapshot static pressure at beginning of test and residual pressure while test hydrant is flowing
-
No flow chart needed
-
More accurate
-
Track total GPM used during test
-
Handle high pressure mains requiring two flow hydrants
What it looks like
Node 1 on left in standard pressure only mode.
Node 2 in middle with flow calc mode enabled.
Node 3 on right in standard pressure only mode.
Live display with pressure alert
Test records display
Session stats auto calculated
Step 2 -
Attach Pressure Sender with flow calc enabled to diffuser gauge port. Turn it on and flow hydrant.
Using a Single Pressure Sender
With just a Basic Remote Pressure Set a single person can conduct a fire hydrant flow test.
The 3000' range ensures you can reach the furthest away hydrant.
Step 1 -
Attach Pressure Sender to hydrant with test cap. Turn it on and open valve.
Benefits
-
Save time - a single person can conduct a flow test
-
Save water - user alert when 25% pressure drop is reached shortening test
-
1 button recording - easy to snapshot static pressure at beginning of test and residual pressure while hydrant is flowing
What it looks like
Single Pressure Sender display
Live display with pressure alert
Test records display
Battery life for Display & Sender
Step 2 -
Flow hydrant and measure gpm using your preferred method
