FLOW SENSOR CALIBRATION
Verify flow sensor calibration during NFPA/UL testing
of the apparatus and delivery to end user.
IMPORTANT!
AN ACCURATE FLOW MEASURING DEVICE MUST
BE USED TO MEASURE THE WATER FLOW WHEN
CALIBRATING THE FLOW SENSOR. USE A SUITABLE
SIZE, SMOOTH BORE, NOZZLE AND AN ACCURATE
AND CALIBRATED PITOT GAUGE INSTRUMENT.
HAND HELD PITOT GAUGES ARE USUALLY NOT
VERY ACCURATE.
MAKE SURE THE SYSTEM IS CALIBRATED WITH AN
ACCURATE FLOW MEASURING DEVICE.

1. Determine the water flow normally expected
from the discharge outlet and establish flow.
2. Make sure the water flow established is within
the range of the flow sensor monitoring the
discharge.
For example, establish a flow rate of 150 GPM
(568 LPM) of water through a nozzle and Pitot
system. Compare the calculated flow value to
the value shown on the control unit display.
