Greyline PSL 5.0 Ultrasonic Level Controller
Designed for pump stations, wet wells, and tank level control – the Greyline PSL 5.0 Pump Station Level Controller has six independently programmable control relays for pump or valve control, level alarms, autodialers, temperature, or fault alarms.
The Greyline PSL 5.0 Pump Station Level Controller is designed for pump station and tank level control applications with the noncontacting sensors mounting just above the well or at the top of a tank. Calibration is simple and easy, use the built-in keypad to calibrate Greyline measurement span, relay set points, pump alternation sequence, and level alarms.
Redundant Sensor Level Control
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.
