 How to Handle Air Bubbles in Fluids with Vortex Flow Meters

To effectively handle air bubbles in fluids with vortex flow meters, consider these strategies:
 
1. Proper Installation
Horizontal Orientation: Install the meter horizontally to reduce air accumulation.
Straight Pipe Sections: Ensure adequate straight runs before and after the meter.
 
2. Use of Air Eliminators
Air Separators: Install air eliminators upstream to remove bubbles.
Vent Systems: Incorporate venting to allow trapped air to escape.
 
3. Flow Conditions Management
Maintain Minimum Flow Rates: Keep flow rates above the meter’s minimum threshold.
Minimize Flow Fluctuations: Avoid rapid changes in flow rates.
 
4. Fluid Conditioning
Defoamers: Use defoaming agents to reduce bubble formation.
Mixing Techniques: Apply mixing to maintain fluid homogeneity.
 
5. Regular Maintenance
Inspect Blockages: Regularly check and clean the meter and piping.
Monitor Pressure: Maintain system pressure to prevent cavitation.
 
6. Calibration Adjustments
Adjust Settings: Modify calibration for bubble presence.
Data Correction: Use algorithms to correct readings based on bubbles.
