Supported Applications
The Omega EchoPulse® LR20 Series is a non-contact, general-purpose pulse radar sensor designed for continuous liquid level measurement in chemical storage and process tanks. The series operates at 26 GHz to provide reliable performance under challenging conditions including corrosive media, light surface foam or agitation, condensation, and vapor.
Documented applications include:
- Aggressive liquids under extremely difficult process conditions
- Tanks constructed of any material (metal or non-metal)
Operating Conditions & Performance
The LR20 Series provides a measurement range from 12" to 65.6' (30cm to 20m) with an accuracy of ± 3mm. The sensor features a dead band of 12" (30cm). Process temperature limits are F: -40° to 302°, C: -40° to 150°. Storage temperature is rated for F: -40° to 176°, C: -40° to 80°.
Pressure ratings span from -14.5 to 72 psi (-1 to 5 bar). The enclosure rating is IP67 with an aluminum housing and silicone gasket. Power supply requirements are 16-26 VDC, with a maximum consumption of 22.5 mA.
Beam Angle by Flange Size
- -30 (3" ANSI): 12° beam angle
- -40 (4" ANSI): 8° beam angle
Configuration Options
The LR20 Series is configured via an integral push-button display module featuring a dot matrix LCD. The display supports units in feet and meters, shows percent of span as a bar graph, and includes an Echo signal curve view.
