Dual Input pH/ORP Controllers are UL, CSA, and CE compliant.
Accepting 2 electrode signals in any combination of pH and ORP, WDP400 Series dual input pH/ORP controllers suit industrial, commercial, and municipal water treatment applications. There are 4 control outputs, available as on/off control relays, or as pulse proportional outputs to directly drive electronic metering pumps. Each control output can be assigned to either electrode, and relays can be...

Feed Sensor verifies flow of liquid through pumps.
PosiFlowO, suitable for EH and EZ Series pumps, detects flow of liquid output by pump, which verifies metering pump is moving liquid and has not lost prime. It does not incorporate any moving parts, and offers preserved flow path to eliminate plugging or jamming. Output signal stops if pump loses prime, is in dead-head condition, or if pump loses pressure due to broken discharge line. Input...
