The new PSL Pump Station Level Controller features a non-contacting ultrasonic sensor, isolated 4-20mA output and 6 programmable control relays for pump control, pump alternation, and for level alarms. It is designed for sewage lift stations, wet wells and storage tanks. An automatic pump run time logging and reporting system helps operators to plan pump maintenance and identify "lazy" pumps before they fail.

Each Greyline PSL includes the Greyline software program PSL Remote for Windows™. Operators can prepare and save calibrations in advance and download to the PSL directly through it's password-protected RS232 interface. Or dial-up PSL pump stations through regular phone lines and modems to adjust calibration and observe level and relay states in real time. Calibration and relay set points can also be changed through the Greyline PSL's built-in keypad.
