3.3 Mounting restrictions
3.3.1 General installation principles
Figure 3-1: General mounting restictions
1 Fully support the weight of the meter. The meter can be supported with clamps close to the connecting flanges.
2 Do not use extreme reductions in process pipework size.
3 Make sure that the process pipework is full at all times.
4 Do not let the flow fall in the process pipework. Low process flow will cause a measuring error.
5 If the meter has been installed with an open-ended down-pipe, Install an orifice plate or restrictor (1) to make sure
that the pipework remains full during measurement. A fast-acting batch or shut-off valve (2) should also be installed
downstream of the meter.
6 It is recommended that you DO NOT mount the meter at the highest point in the pipework because it can cause air /
gas to collect in the meter.
