The new PSL 5.0 Pump Station Level Controller from Greyline Instruments features redundant level sensing. It includes a non-contacting ultrasonic sensor and users can also connect a loop-powered pressure sensor for redundant sensing in applications with foam or grease. The controller will recalibrate the pressure sensor automatically and switch back and forth from ultrasonic level to the pressure sensor as required. It is designed for sewage lift stations, wet wells and storage tanks. Calibration and relay set points are easy to enter through a user-friendly keypad and menu system.
