Description
The Pool Chemical Dosing Controller automatically measures and controls the two most important pool water parameters: pH and free chlorine (or ORP). Probes in a flow cell read the water continuously, and the controller drives dosing pumps for acid and chlorine to keep both values on target. It replaces manual testing and hand dosing with steady, round-the-clock control.
Pools in Oman face high temperatures, strong sunlight and heavy bather loads, which use up chlorine quickly and push pH up. Automatic control keeps water clear, safe and comfortable.
What the Pool Chemical Dosing Controller does
- Keeps pH around 7.2–7.6, where chlorine works best and water is comfortable for eyes and skin
- Maintains free chlorine (or ORP) at the set point to control bacteria and algae
- Prevents over-dosing that causes strong smells, irritation and wasted chemical
- Alarms for high or low readings, low chemical level and no flow
System components
- Digital dual-channel controller for pH and chlorine / ORP
- pH electrode and chlorine or ORP probe in a flow cell
- Two electromagnetic dosing pumps (acid and chlorine)
- Chemical tanks with suction lances and level switches
- Injection valves, sampling line and flow switch

Suitable pools
The Pool Chemical Dosing Controller suits private villa pools, compound and residential tower pools, hotel and resort pools, school and club pools, and spas. We size pumps to pool volume and turnover, and install the flow cell on the filtration return line. See related equipment in our dosing systems range and pool chemicals. For background on pool chemistry, see Wikipedia.
Maintenance
Calibrate pH and chlorine probes every 2 to 4 weeks using test kits and buffer solutions. Clean probes regularly and replace them every 12 to 18 months. Check pump valves and refill chemical tanks as needed. Farz Water offers pool dosing AMC contracts.
Frequently asked questions
Can it work with salt chlorinators? Yes. The controller can switch a salt chlorinator instead of a chlorine pump.
Do I still need to test water? Yes, weekly manual tests confirm probe accuracy.
