Open Feed Or Discharge; Down Going Pipeline Over 5 M /16 Ft Length; Position Of Control Valve - KROHNE OPTISONIC 6300 Handbook

OPTISONIC 6300

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.
Figure 3-3: Open feed or discharge

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.
