PSL 5.0 Ultrasonic Level Controller Description：

User's Manual Datasheet

The PSL 5.0 Pump and Lift Station Level Controller is an ultrasonic level sensor that mounts above the liquid surface for accurate and reliable non-contacting level measurement. The PSL 5.0 is ideal for sewage pump stations, lift stations, wet wells, and tank level measurements. The unit includes six independently programmable control relays for pump or valve control, level alarms, dialers, temperature alarm, and echo loss alarms.

The easy-to-use simple menu system and built-in keypad can be used to program application parameters such as measurement ranges, relay set points, and pump alternation sequences. The PSL 5.0 also includes the ability to connect a submersible pressure sensor, or any other 4-20mA level sensor, for fail-safe hybrid sensing. Perfect for wastewater control, sump control, wet well level monitoring, and industrial applications where backup measurement sensors are required.
