Ultrasonic Level Transmitters
LU80/81/83/84 Series EchoSpan
DESCRIPTION
The Flowline EchoSpan 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%.
Setup is fast and easy using the push button menu and
LCD display. The LU80/81/83/84 Series features fail-safe
intelligence with diagnostic feedback for easy troubleshooting.
The electronics are housed in a rugged NEMA 4X enclosure–
ideal for ultrapure, corrosive, waste, and slurry applications.
