Fluid Metering, Inc. Awarded Patent for Valveless Chlorination System


Fluid Metering, Inc. is proud to have received a patent for their NEW Chloritrol(TM) valveless metering system for accurate, maintenance-free injection of sodium hypochlorite for purification of municipal drinking water.

Accurately metering liquid sodium hypochlorite presents a unique challenge because of the fluid's tendency to out-gas. Many conditions including elevated temperatures, exposure to UV radiation, and cavitation, in addition to, contact with metallic and organic impurities, tend to increase sodium hypochlorite out-gassing.

The resulting gas bubbles present a condition known as "gas lock" which adversely affects the efficiency and accuracy of the injection pump's output. This, in turn, can significantly reduce the amount of chlorine added, and in the worst case, cause the pump to completely lose prime.

The Chloritrol(TM) System is a unique valveless duplex pump design. The first pump head is high pressure and injects the sodium hypochlorite directly into the water main. The second pump head functions to remove out-gas bubbles from the inlet side of the high-pressure pump head.

Each pump head features Fluid Metering's patented CeramPump® pumping principle, which uses one moving part, a rotating and reciprocating ceramic piston which accomplishes both the pumping and the valving functions. Eliminating valves, typically present in other metering technologies, virtually eliminates costly downtime for repair and maintenance.

Flow rate is controlled by FMI's Model V300 Variable Flow Controller, which accepts 4-20 mA, 0-5 VDC, and 0-10 VDC, signals from process sensors and instrumentation. Flow rate can be manually controlled as well using convenient from panel membrane switches and LED readout.

The Chloritrol(TM) has been field tested in very demanding applications, and demonstrated that it exceeds performance expectations. It is also noted that the size of the system, as well as energy consumption, is a fraction of that of conventional injection pumps.

In addition to sanitizing of drinking water, the Chloritrol is an excellent choice for accurate sodium hypochlorite addition for municipal swimming pools, water parks, resorts, food processing plants, and waste treatment applications.

Fluid Metering, Inc. has nearly 50 years experience providing dispensers and pumps for the most critical low flow, high precision applications. Details of the Chloritrol(TM) System are available at the Fluid Metering website: www.fmipump.com,
