OPERATIONAL STARTUP
The following steps should be followed when installing and starting the meter�
MAKE SURE THAT FLUID FLOW HAS BEEN SHUT OFF AND PRESSURE IN THE
LINE RELEASED BEFORE ATTEMPTING TO INSTALL THE METER IN AN EXISTING
SYSTEM.
1� After meter installation, close the isolation valves and open the bypass valve� Flow
liquid 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.
2� Open upstream isolating valve slowly to eliminate hydraulic shock while charging the
meter with the liquid� Open the valve to full open�
3� Open downstream isolating valve to permit meter to operate�
4� Close the bypass valve to a full closed position�
5� Adjust the downstream valve to provide the required flow rate through the meter�
OTE:
N
The downstream valve may be used as a control valve�
