Large-scale water systems that require controlled flow of high volumes of water rely on pump level controls to ensure smooth-running processes and carefully monitored current loads. To better help these municipal water, wastewater and sewage treatment plants meet their flow control needs, ATC Diversified Electronics, a member of the Marsh Bellofram Group of Companies, has introduced its new LPC series liquid level pump controller. This 8-pin plug-in conductive unit uses two probes to sense tank level and lets users select the mode of operation¡ªdrain or fill.
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.
