The PULSAtron Series MP chemical metering pump offers automatic control; 4-20mA and 20-4mA current signals and external pacing input. Signal level or power level relay output for external device control. There are alarm signals for signal loss, full count, circuit failure, pulse overflow and pulse rate high. Liquid low level indicator capability is standard. Pulse signals can be multiplied or divided by 1 to 999. Pulsatron Series MP has models available having pressure capabilities to 300 psi (21 bar) @ 3 gpd (0.5 lph), and flow capacities to 504 gpd (79.5 bar) @ 20 psi (1.3 bar), with a turndown ratio of 1000:1. Metering performance is reproducible to within +/- 2% maximum capacity.
