One kind of popular and cost-effective online pH/ORP controller.

Widely used for electric power,electronics,metallurgy,petrochemical,pharmaceutical ,food and  beverage,environmental protection field .




Meter, time clock dual mode. In flow mode, the internal flow transmitter realizes the function of setting water volume as required. After setting regeneration water volume and cleaning water volume of exchange tank, the period of softening water amount (ton) according to the hardness of the raw water, each station decreases to “0” according to the set value, and stops decreasing and maintains when the water is out of service or no water.

High Cost-Effective ,widely used for chemical industry,paper making industry,industrial coating,pharmaceutical,food,beverage,municipal water,Environmental and so on.

1) Working Position : Service->Back Wash->Brine and slow Rinse->fast rinse->Refill softened water->service.
Downflow type .Working Position : Service->Back Wash->Brine and slow Rinse->fast rinse->Refill->service.
2) Using ceramic moving valve disk, small rotation torque.
3) Abrasion resistance of sealing surface, outstanding and long-lived deal.
4) It could be operated with pressure directly.

High Cost-Effective ,widely used for chemical industry,paper making industry,industrial coating,pharmaceutical,food,beverage,municipal water,Environmental and so on.

On-line analysis and process control of the oil refining, metallurgy,chemical synthesis industry process;
