The Pulsatron Plus Series CL pump provides conductivity monitoring and control with a Limit Timer that controls the feed time. Tower feed and bleed are initiated when the conductivity level reaches the user-specified set point. The programmable limit timer allows the operator to specify the maximum pumping time for the feed cycle. The Series CL includes a conductivity sensor, bleed relay and a user programmable limit timer. 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.
