Ultrasonic Level Transmitter LU2 Series EchoSonic

Ultrasonic Level Transmitter

 

The LU2 Series Ultrasonic Level Transmitter provides non-contact liquid level measurement with a reversible 4-20 mA output. These ultrasonic level transmitters are available in three measurement ranges from 8.2' to 32.8' (2.5 to 10m), and an accuracy of ±0.2%. The water level sensor with transmitter is ideal for ultrapure, corrosive, waste, and slurry applications. Designed for use in Building Automation Systems, BAS, and HVAC applications, the level transmitter can be quickly configured using WebCal software. The software offers pre-programmed menus, tank set point graphics, and custom wiring diagrams. User can define loop failsafe, start-up condition, output at empty, and specific tank levels.
