Water Flowmeter Calibration
It is critical that an accurate flow measuring device be used to measure water flow to calibrate all water flowmeter(s).
Use a suitable size smooth bore nozzle and an accurate pitot gauge instrument. Determine the water flow normally expected
from that discharge outlet.
For example:
2.5” discharge -- establish a flow of 250GPM (937LPM) of water through a nozzle and measure flow
with a pitot gauge.
For example:
4” monitor – establish a flow of 1250GPM (4687LPM) of water through the straight-bore tip and
measure flow with a pitot gauge. Refer to NFPA #1901 or Elkhart Brass catalog or other resources to secure
standard flow charts, pitot pressure, and tip sizes.
