The Pulsatron Plus Series CW pump provides conductivity control with a water meter feed. Bleed is initiated when the conductivity level reaches the user-specified set point. Chemical feed is initiated and controlled by input from a water meter. The Series CW includes a solenoid actuated metering pump, conductivity sensor, bleed relay and a dry contact input for water meter control. Four distinct models are available, having pressure capabilities to 150 PSIG (10 BAR) @ 6 GPD (0.9 lph), and flow capacities to 30 GPD (4.7 lph) @ 100 PSIG (7.0 BAR), with a turndown ratios up to 100:1. Metering performance us reproducible to within ± 2% of maximum capacity.
