Cautions for vortex flowmeter installation
1. Ensure all pipework is adequately supported and no vibration.
2. Take care to ensure the correct direction of flow as indicated by the arrow on the flowmeter body.
3. Pipes must be fully filled with liquids. It is essential that pipes remain fully filled at all times, otherwise flow rate indications may be affected and
measurement errors may be caused.
4. Avoid Air Bubbles. If air bubbles enter a measurement pipe, flow rate indications may be affected and measurement errors may be caused.
5. Avoid installing the flowmeter downstream of a pressure reducing valve as this may cause inaccuracies and / or possibly damage. Similarly,
avoid installing the flow meter downstream of a partially open valve.
6. The minimum recommended lengths of straight pipe are 20 D upstream and 10 D downstream.
7. Avoid installation locations near equipment producing electrical interference such as electric motors, transformers,variable frequency, etc.
