3 Key Applications
1. Reverse Osmosis Systems
• Install Position:
RO inlet (raw water)
Product water line
Reject stream
2. DI Water Systems
• Flow Verification:
Resin bed backwash
Regeneration cycles
3. Chemical Dosing
✔ Acid/alkali flow monitoring
✔ Antiscalant injection control
Installation Best Practices
1. Orientation Requirements
• Must be vertically installed
• Max 5° deviation from plumb
• Upstream straight pipe: 5x diameter
2. Connection Tips
✔ Use PTFE tape on threads
✔ Support piping independently
✔ Install isolation valves
3. Calibration
• Check annually with master meter
• Adjust for viscosity changes
Maintenance Protocol
🔧 Monthly: Clean viewing window
💧 Quarterly: Verify float movement
🧪 Biannual: Full calibration check
⚠️ Annual: O-ring replacement
Pro Tip: Install strainer upstream to prevent clogging
