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.
