Open feed or discharge
Install meter on a lowered section of the pipe to make sure that there is a full pipe condition.
Down going pipeline over 5 m / 16 ft length
Install an air vent downstream of the flowmeter to prevent vacuum. It may cause gases to come
out of solution (cavitate) that prevent a proper measurement.
Position of control valve
Always install control valves downstream of the flowmeter in order to avoid cavitation or
distortion of the flow profile.
