Ultrasonic Level Transmitters

 

The general purpose LU80/81/83/84 Series ultrasonic level transmitter provides non-contact liquid level measurement up to 32.8' (10m), with an accuracy of ±0.2%. The level transmitter uses a liquid level sensor to measure liquid levels. Setup is fast and easy using the push button menu and LCD display. This can be used as a water level sensor or for other liquids. The LU80/81/83/84 Series features fail-safe intelligence with diagnostic feedback for easy troubleshooting. It is designed to achieve reliable liquid level control in Building Automation Systems, BAS, and HVAC applications. The electronics are housed in a rugged NEMA 4X enclosure–ideal for ultrapure, corrosive, waste, and slurry environments.
