3.4.2 Mounting the meter
Mounting positions
1 The meter can be mounted at an angle but it is recommended that the flow is uphill.
2 Avoid mounting the meter with the flow running downhill because it can cause siphoning. If the meter has to be mount-
ed with the flow running downhill, install an orifice plate or control valve downstream of the meter to maintain back-
pressure.
3 Horizontal mounting with flow running left to right.
4 Avoid mounting meter with long vertical runs after the meter as it can cause cavitation. Where the installation includes
a vertical run after the meter, install an orifice plate or control valve downstream to maintain backpressure.
5 The meter can be mounted vertically but it is recommended that the flow is uphill.
6 Avoid mounting the meter vertically with the flow running downhill. This can cause siphoning. If the meter has to be
installed this way, install an orifice plate or control valve downstream to maintain backpressure.
