The PSL Pump Station Level Controller features a non-contacting ultrasonic, isolated 4-20mA output and six programmable control relays for pump control, pump alternation, and for level alarms. It is designed for sewage lift stations, wet walls, 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 product includes the Greyline software program PSL Remote for Windows. Operators can prepare and save calibration in advance and download to the controller directly through its password-protected RS232 interface. Users can also dial-up pump stations through regular phone lines and modems to adjust calibration and observe level and relay states in real time.
