Pump Station Level Controller

The PSL 5.0 Pump Station Level Controller includes a non-contacting ultrasonic sensor and connects to a loop-powered pressure sensor for redundant sensing in applications with foam or grease. It recalibrates the pressure sensor and switches back and forth from ultrasonic to the pressure sensor. The controller is designed for sewage lift stations, wet wells and storage tanks. A keypad and menu system make calibration and relay set points easy to enter. An automatic pump run time logging and reporting system helps operators plan pump maintenance and identify “lazy” pumps. It includes an isolated 4-20mA output and six programmable control relays for pump control, pump alternation and level alarms. Intrinsically safe sensor and a built-in data logger are optional.
