FL-9900 flow transmitter adopts all-digital circuit design, which has the characteristics of simple circuit structure, high precision, good reproducibility, strong anti-interference ability, high protection level, easy installation and use. Widely used in water treatment, cooling water, chemical, biopharmaceutical, power plants, cement plants, sewage treatment, colleges and universities, research institutes and other industrial processes real-time, on-line monitoring of fluids。


Suitable for large residential/light commercial applications
Fully adjustable, 5-cycle control delivers controlled upflow backwash, downflow brining and slow rinse, rapid rinse, timed brine refill and downflow service
Backwash capacity handles tanks up to 24″ diameter
Mechanical control (7- or 12-day clock or metered initiated regeneration)
Valve body is solid, lead-free brass
Time tested, hydraulically-balanced piston, seal, and spacer concept to pilot service flow and regeneration


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.
