Omega LVU800 Series

The Omega LVU800 Series is a general-purpose ultrasonic level transmitter that provides a loop powered 4-20 mA output. The 4-20 mA output can be used to provide the proportional level of liquid in any tank or vessel. The signal can be connected to any device that accepts a loop powered 4-20 mA signal, such as a PLC, SCADA, DCS, display, controller, etc.

New Features

Simple configuration with push-button configuration
Adjustable Loop Fail-Safe, Hold Last, Empty, Full, 21 mA, 22 mA
Easy to reverse mA output, 4-20 mA to 20-4 mA
Increased output filtering

Typical Applications
