3.5.3 Open feed or discharge
Install meter on a lowered section of the pipe to ensure a full pipe condition through the meter.
3.5.4 Down going pipeline over 5 m /16 ft length
Install air vent downstream of the flow meter to prevent vacuum. Although this will not harm the
meter, it may cause gases to come out of solution (cavitate) and interfere with proper
measurements.
3.5.5 Position of control valve
Always install control valves downstream of flowmeter in order to avoid cavitation or distortion
of flow profile.
