The Greyline Instruments PSL 5.0 level controller uses a non-contacting ultrasonic sensor mounted above the liquid and is ideal for sewage pump stations, lift stations, wet wells and tank level control. The PSL 5.0 includes six independently programmable control relays for pump or valve control, level alarms, dialers, temperature alarm and echo-loss alarm.

Setting up and using the PSL 5.0 is easy. Simply 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. 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 unit's backlit LCD display.

The PSL 5.0 sets a new level of reliability. It operates with an ultrasonic level transducer as its primary sensor but also accepts connections from 4-20mA level sensors for redundancy. If the ultrasonic transducer loses signal from foam on the water surface for example, the redundant sensor will take over reading instantly. As soon as the ultrasonic sensor receives new echoes, it will resume function as the primary sensor. The PSL 5.0 will auto-calibrate the redundant sensor and monitor it continuously to ensure availability during primary sensor failure.
