CL-9500 residual chlorine controller is a new controller. This meter has a high degree of intelligence and flexibility. It can measure Residual chlorine value and temperature at the same time. It is widely used in urban sewage treatment plants, water supply and other industries and can continuously measure the Residual chlorine value of solution.


Flexible 7 or 12 day time clock or meter initiated regeneration
Fully adjustable, 5-cycle control delivers upflow back wash, downflow brining, slow rinse, rapid rinse and down flow service
Designed for single tank or multi-tank systems, alternating or interlocking
Continuous flow rate of 250 GPM


1) Working Position : Filter->Back Wash->Fast Rinse->Filter
2) Using ceramic moving valve disk , small rotation torque
3) Abrasion resistance of the sealing surface, outstanding and long-lived deal.
4) It could be operated with pressure directly.



Typical applications • Widely used in thermal boiler deaerator water and large and medium-sized industrial boiler feed water; • Operational supervision of reactor Primary circuit, secondary circuit circuits and condensate system; • On-line analysis of dissolved oxygen in circulating water of heat exchange system; • Deaeration control of marine fresh water system, thermal system and…
