New Pump and Lift Station Level Controller
Ideal for sewage pump stations, lift stations, wet wells and tank level control with a non-contacting ultrasonic sensor mounted above the liquid. The new Greyline PSL 5.0 Level Controller has 6 independently programmable control relays for pump or valve control, level alarms, dialers, temperature alarm and echo-loss alarm.

Mount the non-contacting, ultrasonic sensor in the tank or wet well and install the watertight electronics in the control room or any location within 500 ft / 150 m. Use the simple menu system and built-in keypad to set up measurement range, relay set points and pump alternation sequence. A relay/pump run time report is updated and stored automatically for viewing on the PSL 5.0 backlit LCD display.

For hazardous locations, the ultrasonic sensor is rated Intrinsically Safe with an optional safety barrier. It is rated for measurement ranges up to 32 ft / 10 m, or use the optional PVC Sensor rated for 50 ft / 15.6 m measurement range.

New Dual-Technology Sensor Feature for Redundant Level Monitoring
Connect a submersible pressure sensor or other 4-20mA level transmitter to the PSL 5.0 for fail-safe hybrid sensing.
