Liquid Hypochlorite Injection System Features Valveless Metering

Fluid Metering Inc. (FMI) introduces its new patented Chloritrol valveless metering system for accurate, maintenance-free injection of liquid sodium and calcium hypochlorite for treatment of municipal drinking water.

Accurately metering of liquid sodium hypochlorite presents a unique challenge because of the fluid’s tendency to out-gas.  

The Chloritrol system is a valveless duplex pump design.  The primary pump injects liquid hypochlorite directly into the water main. The secondary pump removes out-gas bubbles from the system preventing loss of prime.  The Chloritrol will self prime against pressures up to 125 psi.  Internal components are made of sapphire-hard ceramics, which provide long term drift-free accuracy.

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.

Fluid Metering will be exhibiting the Chloritrol at the ACE/AWWA Show in June. They will be in Booth #947.
