Installation points to watch:-<br />
1. Ensure all pipework is adequately supported and properly aligned.<br />
2. The minimum recommended lengths of straight pipe are 6 D upstream and 3 D downstream.<br />
3. Take care to ensure the correct direction of flow as indicated by the arrow on the<br />
flowmeter body.<br />
4. Take precautions to avoid reverse flow through the flowmeter.<br />
5. Avoid installing the flowmeter downstream of a pressure reducing valve as this may cause<br />
inaccuracies and/or possibly damage. Similarly, avoid installing the flowmeter downstream<br />
of a partially open valve.<br />
6. Remember that actuated valves may cause rapid pressure fluctuations which could cause<br />
some damage.<br />
7. Take care not to exceed temperature limitation for pressure and temperature transmitters.<br />
8. Please read Section 5 before wiring the system.<br />
