The patented Chloritrol metering system performs accurate, maintenance-free injection of liquid sodium hypochlorite or calcium hypochlorite for treating municipal drinking water. Its unique valveless duplex-pump design features a primary pump that injects liquid hypochlorite directly into the water main and a secondary pump that removes out-gassed bubbles from the system to prevent loss of prime. It self-primes against pressures up to 125 psi. Internal components are made of ceramic, which provides long-term drift-free accuracy. Flowrate is controlled by the manufacturer’s Model V300 variable-flow controller, which accepts 4–20-mA, 0–5 VDC, and 0–10 VDC signals from process sensors and instrumentation. Alternatively, flowrate can be manually controlled via front-panel membrane switches and a light-emitting diode (LED) readout.
