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 .

Fully adjustable, 5-cycle control delivers upflow backwash, downflow brining, slow rinse, rapid rinse, brine refill, and downflow service
Time-tested, hydraulically-balanced piston, seal and spacer, controls service flow and regeneration
Non-corrosive, fiber-reinforced polymer construction
Excellent flow rates (19 GPM continuous, 24 GPM peak)
Backwash capacity handles tanks up to 16″ diameter for softener, and filter

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

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

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


Turbidity is the expression of suspended objects in water to the degree of obstruction of light transmission. This product uses RS485 interface to communicate with the digital sensor, high data accuracy, strong anti-interference, can directly control the digital sensor calibration and automatic cleaning and other functions.
