Automatic, hybrid pump station level controller with a non-contacting, ultrasonic sensor. Pump Station Level Control, Monitoring & Reporting Ideal for Level Control 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 RIGHT METER FOR • Pump Stations • Tank Level Control 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 152.4 m (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 instrument’s backlit LCD display. Dual-Technology Sensor Feature: Redundant Level Sensing Connect a submersible pressure sensor or another 4-20mA level transmitter to the PSL 5.0 for failsafe hybrid sensing. The PSL 5.0 will auto-calibrate the redundant sensor and if the signal is lost to the ultrasonic sensor, the redundant sensor will seamlessly I N F O @ P U L S A R M E A S U R E M E N T . C O M take over monitoring until the signal resumes from the ultrasonic. The redundant sensor is continuously monitored to ensure availability during primary sensor failure. Easy to Install with NonContacting Sensor 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

measurement span, relay set points, pump alternation sequence, and level alarms. Assign the six built-in control relays for ON / OFF pump control, high- or low-level alarms, autodialer activation, air temperature alarm, or sensor echo loss alarm. Connect the isolated 4-20mA output to your SCADA system, PLC’s, or recorders, for easy integration with existing plant control systems. Redundant Sensor Level Control Non-contacting, ultrasonic sensor 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...
