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 ex-
pected from the discharge outlet and
establish flow.
2. Make sure the water flow established is
within the range of the flow sensor moni-
toring 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.
