⚙️ How it works

The system has two main parts:

1) Sense (measurement)

\n
• A flow cell constantly samples pool water
\n
• Sensors measure:\n
  \n
  • pH probe → acidity level
  \n
  • ORP probe → chlorine strength (sanitizing power)
  \n
  \n
\n

2) Dispense (chemical control)

It can control:

\n
• 🧂 Salt chlorinator output (more/less chlorine production)
\n
• 🧪 Acid dosing pump (to lower pH)
\n
• 🫧 CO₂ system (in some setups)
\n

🧱 Main components

\n
• Flow cell chamber (water sample loop)
\n
• pH probe
\n
• ORP probe
\n
• Control module (HL-CHEM / AQL-CHEM)
\n
• Injection control outputs (acid/chlorine systems)
\n

👍 Key benefits

✔ Automatic water balancing (less manual testing)
✔ More stable chlorine levels (no big highs/lows)
✔ Better compatibility with saltwater pools
✔ Integrates into full Hayward automation systems
✔ Can be monitored via app (with OmniLogic setups)

⚠️ Real-world limitations

\n
• ❌ Not fully “set and forget” (still needs calibration)
\n
• ❌ Probes require cleaning and replacement over time
\n
• ❌ Flow cell must maintain correct water flow or readings become wrong
\n
• ❌ Can be expensive compared to manual testing
\n
• ❌ Acid/CO₂ systems still require refills and maintenance
