3.4.6 Pipework reducers
Always avoid extreme step changes in pipe size. Use pipework reducers, where there is a large
difference between pipework size and meter flanges.
3.4.7 Flexible connections
Flexible connections can be used but because of the high flow rates associated with large
diameter meters, it is recommended that flexible connections are not used on meters larger
than size 80.
3.4.8 Hygienic installations
1 Install the meter at an angle to allow self-draining.
2 DO NOT install the meter horizontally.
