OPERATIONAL STARTUP
Follow these steps when installing and starting the meter .
MAKE SURE TO SHUT OFF FLUID FLOW AND RELEASE PRESSURE IN THE LINE BEFORE ATTEMPTING TO INSTALL THE
METER IN AN EXISTING SYSTEM.
AVERTISSEMENT
ASSUREZ-VOUS QUE LE FLUX DE FLUIDE A ÉTÉ COUPÉ ET DE LA PRESSION DANS LA LIGNE A ÉTÉ LIBÉRÉE AVANT
D’ESSAYER D’INSTALLER LE MÈTRE DANS UN SYSTÈME ACTUEL.
After meter installation, close the isolation valves and open the bypass valve . Allow liquid to flow through the bypass valve for
sufficient time to eliminate any air or gas in the flow line .
HIGH VELOCITY AIR OR GAS MAY DAMAGE THE INTERNAL COMPONENTS OF THE METER.
ATTENTION
DES DOMMAGES PEUVENT ÊTRE PROVOQUÉS EN FRAPPANT UN MÈTRE VIDE AVEC UN JET D’ÉCOULEMENT DE VITESSE
ÉLEVÉE.
1 . Open the upstream isolating valve slowly to eliminate hydraulic shock while charging the meter with the liquid . Open the
valve to full open .
2 . Open downstream isolating valve to permit meter to operate .
3 . Close the bypass valve to a full closed position .
4 . Adjust the downstream valve to provide the required flow rate through the meter .
OTE:
N
If necessary, use the downstream valve as a control valve .
