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.

CALIBRACIÓN DEL SENSOR DE CAUDAL
Verifique la calibración del sensor de caudal durante
la prueba según la NFPA/UL del aparato y entrega
al usuario final.
¡IMPORTANTE!
SE DEBE USAR UN DISPOSITIVO DE MEDICIÓN
PRECISO DE CAUDAL PARA MEDIR EL CAUDAL
DE AGUA CUANDO SE CALIBRE EL SENSOR
DE CAUDAL. USE UNA BOQUILLA DE TAMAÑO
APROPIADO Y DE PARED INTERIOR LISA Y UN
INSTRUMENTO DE MEDICIÓN PITOT PRECISO Y
CALIBRADO. LOS MEDIDORES PORTÁTILES PITOT
GENERALMENTE NO SON MUY PRECISOS.
ASEGÚRESE DE QUE EL SISTEMA ESTÉ
CALIBRADO CON UN DISPOSITIVO PRECISO DE
MEDICIÓN DE CAUDAL.
Determine el caudal de agua que normalmente 1.
se espera desde la salida de descarga y fije el
caudal.
Asegúrese de que el caudal de agua establecido
2.
esté dentro del rango del sensor de caudal que
monitorea la descarga.
Por ejemplo, fije un caudal de 568 LPM (150
GPM) de agua a través de una boquilla y un
sistema Pitot. Compare el valor de caudal
calculado con el valor mostrado en la pantalla de
la unidad de control.
