Liquid-level pump controller ensures smooth flowrates
To help municipal water, wastewater and sewage-treatment plants meet their flow-control needs, this company has introduced its new LPC series liquid level pump controller (photo). This eight-pin, plug-in conductive unit uses two probes to sense tank level and lets users select the mode of operation. In drain mode (pump down), the output relay picks up and the LED turns on when liquid reaches the high-level probe. The relay drops out and the LED turns off when liquid falls below the low-level probe. In fill mode (pump up), the output relay picks up and the LED turns on when liquid falls below the low-level probe. The relay drops out and the LED turns off when liquid reaches the high level probe. — ATC Diversified Electronics, Newell, W.Va.
