3.2.3 Pipework requirements
Good engineering practice should be followed at all times:
• Correct preparation, welding and finishing techniques
• Correctly sized gaskets
• Correctly aligned flanges and gaskets
• Connecting pipe work should match the internal diameter of the flowmeter.
Maximum pipe diameter mismatch should not exceed:
– 1 mm (0.04 inch) for diameters < DN 200 (8")
– 3 mm (0.12 inch) for diameters  DN 200 (8")
For further information please refer to ISO 14511.
