Inlet and outlet conditions

• Ensure sufficient distance between meter and bends, pump and valves.
• Install valves influencing the flow profile after the flowmeter. The only exception is
installation of the sensor in a vertical pipe (upwards flow direction). In installations in a
vertical pipe a valve below the sensor is required to allow zero-point adjustment.
Note
Select a valve not altering flow when fully opened.
