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.

Single stage RO controller used for conductivity monitoring and process program control .


Fluorescence quenching principle, no need for internal filling, no oxygen consumption, and easy maintenance;
The service life of the fluorescent membrane cap is more than one year (under ideal conditions);
Original altitude, atmospheric oxygen partial pressure, temperature compensation, to improve the authenticity of the data;

ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.

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.
